Abstract

This research utilizes waste from PLTU Tanjung Jati B Jepara, namely FABA (Fly ash Bottom Ash) as an alternative to fine and coarse aggregate. From this research, the physical properties of faba aggregate can be seen from the results of the faba aggregate sieve analysis test, which obtained a fineness modulus value of 1.74, which is included in the medium aggregate type. The water content of fine aggregate (fly ash) obtained a value of 3.63% and coarse aggregate (bottom ash) obtained a value of 1.5%. The fine aggregate sludge content (fly ash) obtained a value of 0%. The fine aggregate organic substance (fly ash) acquires a reddish brown NaOH color, therefore it must be washed before being used as a concrete mixture. The face dry specific gravity of fine aggregate (fly ash) obtained a value of 2.63 gr/cm2 and coarse aggregate 2.52 gr/cm2. From the data that has been obtained, faba aggregate is considered to have physical properties that meet the requirements for fine aggregate and can be used as a substitute for sand. The results of the final compressive strength of faba concrete and normal concrete at the age of 7 days and 28 days showed that the compressive strength of normal concrete (control) was higher than that of faba concrete. The standard deviation values ​​at the ages of 7 and 28 days are included in perfect working conditions because they have a standard deviation value of less than 3 MPa. From the results of the concrete flexural strength test, only the control concrete was 1;1.5 with a flexural strength of 4.18 MPa, which is close to SNI 2847:2013, namely with a minimum flexural strength of fs = 4.4 MPa. Normal concrete has a higher flexural strength than faba concrete. Based on tests carried out with the planned mix design, the 1:1.5 variation obtained the highest results.

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
