Abstract

The application of mortar is generally intended for non-structural work such as wall plastering, brick adhesive, mortar on river stone foundations, plastering for ceramic installation, brick, paving block, concrete pipes, rosters, and others. Mortar is widely used as a construction material because its ingredients are easily obtainable, and it is simple to work with. The quality of mortar is influenced by its constituent materials, the use of ingredients that meet the required specifications will result in good quality mortar. This study aims to determine the physical characteristics of fine aggregate and fly ash on K-50 mortar and the effect of adding fly ash on the compressive strength of K-50 mortar. The research methodology used is experimental, where experiments are conducted by manipulating or controlling natural conditions through the creation of artificial conditions. The test results of fine aggregate characteristics, including sieve analysis, density, specific gravity, water content, and quartz sand waste meet the specifications and suitable for use in mortar mixtures. The characteristics of fly ash obtained specific gravity of 2.436, loose content weight of 1.576 gr / cm3 and compacted content weight of 1.665 gr / cm³. The effect of adding fly ash on the compressive strength of K-50 mortar was examined for mixture ratios of 1Pcc: 3Psr, 1Pcc: 4Psr, 1Pcc: 5Psr, 1Pcc: 6Psr fly ash addition of 5% and 10%. The results show that the greater the amount of fly ash used, the higher the compressive strength of the mortar. The maximum compressive strength for 5% fly ash is 128.80 kg/cm², while for 10% fly ash it is 179.20 kg/cm², both achieved at the 1Pcc: 3Psr mixture ratio.

Abstract

This study aims to determine the compressive strength, density, and crack pattern of lightweight concrete utilizing polypropylene coated with sand as coarse aggregate and Tayan sand as fine aggregate. The research employs three mix design clusters based on the water-to-cement ratio (w/c): Cluster A with a w/c ratio of 0.347, Cluster B with a w/c ratio of 0.339, and Cluster C with a w/c ratio of 0.319. Cylinder-shaped specimens measuring 15×30 cm were prepared for each cluster. For the 15×30 cm cylinder specimens, the average compressive strength obtained was 21.69 MPa, 22.15 MPa, and 24.53 MPa for Clusters A, B, and C, respectively, with standard deviations of 0.59, 0.49, and 1.51. The density of lightweight concrete was recorded as 1717.54 kg/m³, 1689.17 kg/m³, and 1802.93 kg/m³ for Clusters A, B, and C, respectively. The observed crack pattern corresponds to Type 3, in reference to ASTM C39. Keywords: Lightweight Concrete; Polypropylene; Tayan

Abstract

Cold-formed steel materials are widely used in the construction industry. One such application is closed box cold-formed steel beams, which are commonly used as battens in ceiling structures. Cold-formed steel is produced through cold roll forming or bending processes, resulting in folds along the profile. This study aims to investigate the effects of these folds on stiffness, deflection, ductility, and failure patterns. A total of 18 specimens, with lengths of 500 mm and 1100 mm, were tested using three-point bending tests. The folds were varied in location: placed in the top area, bottom area, and the side area. Tensile coupon tests were also testing to determine the material properties of the cold-formed steel. The results show that beams with a length of 500 mm can carry greater vertical loads compared to those with a length of 1100 mm. Additionally, the displacement and rotation observed in the 500 mm beams were smaller than those in the 1100 mm beams, which more significant deflection and rotation. Beams with folds located in the top area and bottom area shower greater load-carry capacity than those with folds in the web area. The failure patterns of the 500 mm beams were dominantly characterized by excessive deformation in the bottom are due to vertical loading. Similar deformation was observed in the 1100 mm beams. This excessive deformation occurred beneath the point of vertical load application with a roller-type support. Momen capacity of the experimental test results was also compared with the theoretical calculation using the Direct Strength Method, the results showed a comparative value that was almost close, but it is better to modify the formula to the theoretical formula of the Direct Strength Method for cross-sections with folds.

Abstract

This study evaluates the effect of beam length and fold position on the flexural performance, deflection, and failure pattern of closed-box cold-formed steel beams with dimensions of 32 mm × 31 mm × 0.3 mm under four-point bending tests. A total of 18 specimens were tested using this method with two length variations, 500 mm and 1100 mm, and fold positions located either on the top flange, bottom flange, or side web. The results show that the 500 mm beams were able to carry greater vertical loads compared to the 1100 mm beams, with smaller mid-span deflections and relatively smaller rotation. In contrast, the 1100 mm beams experienced more significant mid-span deflections and rotations. The presence of folds on the top or bottom flanges increased the beam’s vertical load-carrying capacity by approximately 10% to 15% compared to when the fold was placed on the side web. The failure pattern of the shorter beams was dominated by excessive deformation on the upper part of the beam due to vertical loading, and similar deformation was also observed in the longer beams. This excessive deformation occurred beneath the vertical load application point near the roller support. In addition, comparison with the Direct Strength Method (DSM) revealed that DSM predicted higher flexural moment capacities than those obtained from experiments, M experiment / MDSM ratios ranging from 0.33–0.45 for 500 mm spans and 0.49–0.54 for 1100 mm spans. These results indicate that DSM is more conservative for shorter beams and can serve as a safe preliminary approach for designing cold-formed steel beams subjected to four-point bending.

Abstract

The construction of the Serang–Panimbang Toll Road Section III Phase 2 Package 3 was part of a National Strategic Project requiring a strong foundation to overcome soil settlement. Spun piles were used as the primary foundation to resist both vertical and horizontal loads. This study aimed to determine axial bearing capacity based on pile driving (calendering) and SPT data analysis, calculate lateral bearing capacity, and evaluate pile settlement and displacement. Pile driving analysis showed varying capacities, with the lowest value from the Navy-McKay formula (371.782 kN) and the highest from the WIKA formula (926.061 kN). The Meyerhof α formula from SPT analysis produced the highest axial capacity (1052.162 kN). Lateral bearing capacity based on Broms (1965) exceeded allowable limits in both sand (9608.429 kN) and clay (6272.101 kN). Pile settlement occurred as a response to structural loads acting on the foundation and was influenced by the physical and mechanical properties of the supporting soil beneath. Based on elastic analysis using Vesic’s method (1967), the maximum settlement was (25.224 mm), occurring at the interaction zone between the spun pile and dominant soil layers at foundation depth. This value remained within the safe limit according to SNI 8460:2017. Overall, the spun pile foundation proved effective in maintaining stability under vertical and horizontal force while ensuring structural integrity and sustainability against potential settlement and displacement.

Abstract

The use of alternative materials in concrete mixtures is an important effort to improve concrete performance while reducing dependence on cement. This study aims to investigate the effect of adding Ground Granulated Blast Furnace Slag (GGBFS) as a partial substitute for cement on the properties of concrete, both in fresh and hardened conditions, using a constant dosage of type F superplasticizer at 1% of the cement weight. The GGBFS replacement levels used in this study were 0%, 20%, 30%, and 40%. The tests conducted included slump, unit weight, initial setting time, compressive strength, splitting tensile strength, flexural strength, and modulus of elasticity. The results showed that the use of GGBFS significantly affected compressive strength and splitting tensile strength, with optimum results achieved at the 20% replacement level. In contrast, other properties such as flexural strength and unit weight were not significantly influenced. Therefore, GGBFS can be considered an effective supplementary material in concrete mixtures when used at an appropriate dosage.

Abstract

Sustainable innovation in road construction encourages the use of recycled materials, such as Reclaimed Asphalt Pavement/RAP, as an alternative to reduce dependence on new materials and minimize negative environmental impacts. However, RAP materials generally undergo an aging process that causes a decrease in viscoelastic properties, an increase in stiffness, and a decrease in resistance to cracking and deformation. To address these issues, rejuvenators produced from biomass waste - such as rice husks, bagasse, palm oil waste, and other agricultural residues - are being developed as environmentally friendly solution in restoring the rheological properties of RAP asphalt and improving the performance of the asphalt mixture. The results show that plant-based rejuvenators containing lignin with a chemical structure consisting of carbon, hydrogen, oxygen elements, and have active groups such as aromatic ring structures, aliphatic and aromatic hydroxyl groups, and quinone groups very similar in structure to asphalt can rebalance the proportion of malten and asphaltene fractions in aged asphalt. The use of bio-rejuvenators provides performance that results in a decrease in the complex modulus (G⁎) value and an increase in the phase angle (δ), indicating improved flexibility and reduced stiffness of the asphalt, approaching the characteristics of new asphalt. Furthermore, the addition of biojuvenators also positively impacts resistance to rutting and fatigue, while enhancing the workability of the asphalt mixture, especially in low-temperature applications.

Abstract

The increasing demand for pavement materials necessitates more sustainable solutions, one of which is the utilization of Reclaimed Asphalt Pavement (RAP) containing aged asphalt from recycled layers. However, the high incorporation of RAP often faces challenges such as increased stiffness, reduced ductility, and degradation of viscoelastic properties due to aging. In this context, waste cooking oil (WCO) has attracted significant attention as an eco-friendly and cost-effective rejuvenator. This study presents a systematic literature review on the application of WCO in RAP mixtures, focusing on its chemical characteristics, effects on rheological and mechanical properties, implementation challenges, and performance enhancement strategies through chemical modification and additive incorporation. The findings indicate that WCO effectively reduces binder viscosity, improves flexibility, enhances low-temperature cracking resistance, and extends the fatigue life of RAP mixtures. However, excessive WCO content may reduce Marshall stability and rutting resistance. Synergistic approaches such as polymer addition, nano-material incorporation, or chemical pre-treatment have proven effective in addressing these limitations. This review highlights WCO’s potential as a sustainable rejuvenator while emphasizing the need for further research on dosage optimization, quality standardization, and long-term performance evaluation to support large-scale industrial implementation.

Abstract

The Asphalt Concrete-Binder Course (AC-BC) layer has an important structural function as a binder between the base layer and the wearing layer. This study aims to evaluate the feasibility of the AC-BC layer in terms of thickness and density using the core drill method on the Padang-Pekanbaru Toll Road Section 2 project. Tests were conducted on field and laboratory samples, then the results were compared with the 2018 General Bina Marga Specifications Revision 2. The average thickness of most samples met the minimum standard of 6.0 cm, but there were several points with a thickness <6.0 cm that required evaluation. Field density values ​​ranged from 2.29-2.34 gr/cm³, and degree density between 97.19–99.47%. Most test points met the standard ≥98%, but there were points with values ​​below the standard indicating potential imperfections in the compaction process. Analysis showed that differences in density values ​​were influenced by the mixture temperature during spreading, the delay time between production and spreading, and variations in field implementation. These findings demonstrate the importance of temperature and time control to ensure the quality of AC-BC layer construction. The results of this study can serve as a technical reference for evaluating and improving fieldwork quality in pavement construction projects.
