Ketahanan Mortar Geopolimer Hybrid Abu Terbang Serbuk Karet Variasi Modulus Silikat Pada Suhu Tinggi

---

In Indonesia, industrial waste such as elastic rubber powder from used vehicle tires and fly ash from power plant waste can be used in construction. Fly ash is a geopolymer substance or alternative adhesive that can be used in place of cement in mortar mixtures. The purpose of this study was to examine the effect of silicate modulus (Ms) variation on the resistance of hybrid fly ash geopolymer mortar using rubber powder to high temperature. Tests were conducted including flow value, compressive strength, porosity, density, strength activity index (SAI), stability and mass change. This study used rubber powder as a substitute for fine aggregate at 5%, NaOH concentration of 12 M and an extra PCC cement of 15% by weight of fly ash. The silicate modulus was varied to 1.5, 2, and 2.5. The geopolymer hybrid fly ash rubber powder mortar was rested for 3 days before being cured for 28 days and burned for one hour in oven furnaces set to 250°C, 500°C and 750°C. The results showed that at 250°C the compressive strength value increased in the variation without rubber powder GPCR-0-12M-2.5 by 22.13 MPa and with rubber powder GPCR-5-12M-2.5 by 20.93 MPa, GPCR-5-12M-2.0 by 17 MPa, and GPCR-5-12M-1.5 by 13.12 MPa. At 750°C, the compressive strength decreased in the variation without rubber powder or GPCR 0-12M-2.5 by 33% and in the variation with rubber powder or GPCR 5-12M-2.5 by 29%. The variant including rubber powder had a lesser loss in compressive strength than the variation without rubber powder. As a result, using rubber powder as a fine aggregate alternative can improve resistance at high temperatures. Furthermore, a rise in silicate modulus (Ms) can improve strength and provide resistance at high temperatures.

Keywords: Resistance, high temperature, geopolymer hybrid fly ash mortar,
rubber powder, silicate modulus (Ms).
