Abstract

Self-Compacting Concrete (SCC) is a type of concrete capable of compacting itself without the use of vibrators, characterized by a high slump and the ability to flow under its own weight to fill formwork completely without segregation, thereby simplifying the construction process. The materials used to produce SCC include fine aggregates, coarse aggregates, water, and cement, combined with admixtures in the form of superplasticizers. The superplasticizers added in this study were Consol SG at 0.3% and Consol N11 LN at variations of 0.6%, 1.4%, and 2%. Workability test results for SCC indicated slump flow values of 39.17 cm for 0.6% SCC, 56.72 cm for 1.4% SCC, and 61.24 cm for 2% SCC. L-Shape Box tests yielded results of 0.067 for 0.6% SCC, 0.949 for 1.4% SCC, and 0.987 for 2% SCC. The V-Funnel Test produced times of 32 seconds for 0.6% SCC, 11 seconds for 1.4% SCC, and 8 seconds for 2% SCC. Compressive strength testing of normal concrete showed values of 22.36 MPa at 7 days, 28.79 MPa at 14 days, and 35.28 MPa at 28 days. For SCC with 0.6% admixture, compressive strengths were 23.85 MPa at 7 days, 29.58 MPa at 14 days, and 36.17 MPa at 28 days. SCC with 1.4% admixture yielded compressive strengths of 25.27 MPa at 7 days, 30.16 MPa at 14 days, and 38.26 MPa at 28 days. SCC with 2% admixture reached compressive strengths of 28.04 MPa at 7 days, 33.62 MPa at 14 days, and 38.63 MPa at 28 days. Water absorption tests at 28 days showed values of 120 g for normal concrete, 110 g for SCC with 0.6% admixture, 100 g for SCC with 1.4% admixture, and 110 g for SCC with 2% admixture.

Abstract

Increasing cement consumption in line with growing construction activities has led to higher building costs and rising carbon dioxide (CO2) emissions, both of which contribute to global warming. One potential alternative material is carbide welding waste, a residue generated from welding processes that is often underutilized and frequently becomes waste with the potential to pollute the environment. This study aims to analyze the effect of using carbide welding waste as a partial cement substitute on the physical and mechanical properties of concrete, particularly its water absorption (absorptivity) and compressive strength. The method used is an experimental approach with substitution variations of 6%, 9%, and 12% of carbide welding waste relative to the cement weight. The test results show that these substitution percentages produce different effects on the characteristics of the concrete. A 9% substitution provides the most optimal outcome, with a compressive strength of 28.95 MPa and the lowest absorption value of 2.4417%. These values are superior to those of normal concrete without substitution, which has a compressive strength of 25.64 MPa and an absorption value of 2.7001%. At 6% substitution, the compressive strength reaches 26.74 MPa with an absorption value of 2.5481%, while at 12% substitution, concrete quality declines, with compressive strength dropping to only 22.50 MPa and absorption increasing to 3.2416%. The findings demonstrate that carbide welding waste can be used as a partial cement substitute, with the optimal percentage being 9%.

Abstract

This community service activity was carried out in Sukajadi Village, Talang Kelapa Subdistrict, Banyuasin Regency, with the aim of designing and planning a gate that could represent the local identity of the area. As an architectural element, the gate not only functions as an entrance, but also as a symbol of culture, history, and local wisdom values of the community. The main challenge faced by Sukajadi Village is the absence of a gate that represents the local identity and cultural character of the local community. Through a participatory approach, this activity involved the community, the subdistrict government, and academics in all stages of implementation, from field surveys, interviews with community leaders, focus group discussions, inventory of local potential, to technical design using AutoCAD and SketchUp software. The result of this activity was a modern minimalist gate design with a harmonious blue and cream color composition, complete with the government and university logos as symbols of collaboration. The total planned construction budget of IDR 17,106,814.00 was prepared transparently and agreed upon by all stakeholders. Based on the satisfaction survey results, 100% of respondents expressed satisfaction with the quality of the design and the collaborative process. This activity demonstrates that community service based on participation can strengthen local identity, increase community ownership, and serve as a model for collaboration between academics and residents in sustainable development based on local wisdom.

Abstract

Concrete is a composite material widely used due to its high compressive strength and resistance to structural loads. Environmentally friendly concrete innovation can be achieved through the utilization of waste materials, such as sawdust, along with the addition of chemical admixtures to improve performance. This study aims to analyze the effect of sawdust treated through water immersion and oven drying, as well as the addition of Bestmittel admixture, on the workability and compressive strength of concrete. The sawdust variations used were 1 percent, 3 percent, and 5 percent of the cement weight, while Bestmittel was added at 0.5 percent. The research method employed an experimental laboratory approach involving slump tests, absorption tests, and compressive strength tests at 28 days. The results indicate that the variation containing 3 percent oven-dried sawdust provided the optimum performance in terms of both workability and compressive strength. The addition of sawdust above 3 percent tended to reduce compressive strength due to increased porosity. Therefore, the use of sawdust together with Bestmittel in appropriate proportions can improve concrete quality while simultaneously supporting sustainable waste management.

Abstract

This study evaluates the effect of integrating coconut coir fiber at contents of 2 percent, 2.5 percent, and 3 percent, along with 5 percent silica fume, on the splitting tensile strength performance of concrete. The experimental results show that the 2 percent coconut coir fiber proportion provided the optimal performance, with a tensile strength value reaching 3.12 MPa, or an increase of 12.5 percent compared to the control concrete, which had a tensile strength of 2.5 MPa. Although fiber additions at higher contents of 2.5 percent and 3 percent still contributed to mechanical strength, a significant decline in concrete mixture workability was observed. The synergy between silica fume through its pore-filling effect and natural fibers proved effective in optimizing concrete density and ductility. This study concludes that the combination of these two materials can produce innovative concrete that is stronger and more environmentally friendly as a future construction material solution.

Abstract

The use of porous concrete is a crucial strategy for mitigating surface water runoff in urban areas. However, low compressive strength often poses a major challenge in its application. This study aims to analyze the effect of adding silica fume on the mechanical and hydraulic properties of porous concrete. The research was conducted experimentally in a laboratory setting, following ACI 522R-10 standards for mix proportions and ASTM C39 for compressive strength testing. The silica fume content was varied at 0%, 3%, 5%, and 7% of the total cement weight, with a total of 24 test specimens, each a 10x20 cm cylinder. Test procedures included a slump test for workability, a permeability test, and a 28-day compressive strength test. The results showed that increasing the silica fume content significantly reduced the slump to 0 cm at a 7% increase, indicating that the mixture became stiffer. As the micro-structural density increased, the permeability coefficient decreased from 0.0288 cm/s to 0.0082 cm/s. Although drainage capacity decreased, the compressive strength of the concrete increased significantly by 69.6%, from 6.58 MPa to 11.16 MPa at the 7% content. The novelty of this study lies in identifying the optimal silica fume content to achieve a structural compressive strength above 10 MPa while preserving drainage functionality. These findings confirm that silica fume effectively enhances the mechanical performance and durability of porous concrete, making it highly suitable for use in eco-friendly infrastructure, such as parking lots and neighborhood roads, that require a balance between structural strength and water infiltration efficiency.©The author(s).
