Abstract

Porous geopolymer concrete has gained attention as a sustainable and environmentally friendly alternative to conventional Portland cement-based concrete, utilizing industrial waste such as fly ash. This study investigates the effect of aggregate gradation variations on the mechanical properties, porosity, and sustainability of fly ash-based porous geopolymer concrete. The experimental method was employed, utilizing fly ash as the primary binder, sodium hydroxide (NaOH) as the activator, and coarse aggregates of varying sizes (3/8", 1/2", and 3/4"). The concrete samples were tested for compressive strength and porosity at 7, 14, and 28 days following ASTM standards. The results indicate that aggregate gradation significantly influences the mechanical properties, porosity, and sustainability of geopolymer concrete. Smaller aggregate sizes (3/8") produced higher compressive strength (5.42 MPa at 28 days) but lower porosity, while larger aggregates (3/4") increased porosity but reduced compressive strength. Additionally, the study confirms that geopolymer concrete using fly ash as a binder meets the standard requirements for setting time, specific gravity, and durability. These findings contribute to optimizing porous geopolymer concrete for sustainable construction applications, particularly in drainage and permeable pavement systems, promoting waste utilization and environmental sustainability.  Keyword: Porous geopolymer concrete, fly ash, , porosity, waste, sustainability

Abstract

Utilizing dead rock as a cement additive in the manufacture of paving blocks, and the rock contains CaCO3 which includes limestone as in the content of cement which has lime content (CaO), the aim is to determine the effect of rock on the compressive strength value of paving blocks. Utilization of stone in the manufacture of paving blocks using a mixture of design 0%, 5%, 10%, and 15% of the weight of cement to be used. Manufacture of paving blocks using a ratio of 1: 3 sand cement, cement water factor 0.4 with molds 20 x 10 x 6 cm, compaction weight of 1 paving 3.52 kg and testing compressive strength at 7, 14 and 28 days, using the method (SNI 03- 0691-1996) paving block. From the analysis of compressive strength testing, it was found that the compressive strength of paving blocks increased towards normal paving blocks to produce the highest compressive strength with added rock in the 15% variation at the age of 28 days, which amounted to 45.1 MPa and included the quality of class A paving blocks with SNI 03-0691 (1996) standards. The compressive strength of the 5% variation at 28 days of age is 38.7 MPa and the compressive strength of the 10% variation at 28 days of age is 43.5 MPa. It can be seen that coral stone as a cement additive is able to improve the quality of compressive strength of paving blocks.

Abstract

The development of a green economy in rural areas requires active community participation, particularly from women’s groups, supported by digital transformation and environmentally friendly technology. However, the Women’s Welfare Movement Group (PKK) of Lebak Village, Jepara Regency, faces several challenges, including reliance on conventional agricultural practices, low digital literacy, and the absence of online media for promoting local agricultural products. Therefore, this community service program aimed to empower PKK members through the application of aquaponic technology and the utilization of the Wonderful Taman Sari (WoTaS) digital application to enhance productivity and support sustainable economic practices. The program employed a participatory–educative approach implemented in five stages: socialization, aquaponic technology training, WoTaS application training, intensive mentoring, and evaluation. The results demonstrated a substantial improvement in participants’ knowledge and skills, with an average achievement rate of 91.9%. All participants (100%) were able to operate a simple aquaponic system, while 80% successfully used the WoTaS application independently to promote local products. In conclusion, this program effectively increased community productivity and digital literacy while strengthening the role of rural women in supporting a sustainable green economy.

Abstract

This study investigates the effect of NaOH molarity (10, 12, and 14 M) on gel formation at the geopolymer–artificial aggregate interfacial transition zone (ITZ) for sustainable pavement binder courses. The study focuses on microstructural and chemical characteristics rather than direct mechanical performance. Using XRF, FTIR, and SEM–EDX analyses, the evolution of gel phases from N-A-S-H to hybrid N/C-A-S-H at the interface was systematically characterized. Increasing NaOH molarity enhanced aluminosilicate dissolution and promoted Ca incorporation, as evidenced by the shift of the main Si–O–T band from approximately 1080 cm⁻¹ (10 M) to 960–970 cm⁻¹ (14 M) and the increase in Ca/Si ratio from 0.15 to 0.22. Among the investigated mixtures, the 12 M variant exhibited the most homogeneous and compact ITZ microstructure, characterized by a continuous reaction rim, balanced Si/Al (2.96) and Ca/Si (0.22) ratios, and minimal microcracking observed at the microscopic scale.

Abstract

The use of recycled plastic waste as a binder for paving blocks has been reported in a number of previous studies. However, most of these studies focus on feasibility and do not clearly explain how different plastic types behave mechanically over time. In this study, the compressive strength performance of paving blocks made from polypropylene (PP), polyethylene terephthalate (PET), and high-density polyethylene (HDPE) was experimentally compared using sand or fly ash as fillers. All mixtures were prepared with a fixed composition of 60% plastic and 40% aggregate. Compressive strength testing was carried out at 28 and 56 days using three specimens for each mix. The results show that the HDPE–sand mixture achieved the highest compressive strength at 28 days, reaching 15.7 MPa. Nevertheless, a noticeable reduction in strength was observed at 56 days, particularly in the HDPE-based mixtures. This reduction is mainly associated with polymer shrinkage and the development of interfacial stresses between the plastic binder and the aggregates. Overall, the results indicate that plastic-based paving blocks can meet the requirements of SNI 03–0691–1996 for light-duty applications, although their long-term mechanical stability remains a limitation that needs further attention.
