“…The difference between geopolymer concrete and other conventional concrete is that polymer concrete is not formed from a hydration process but is formed from a chemical reaction. Geopolymer concrete is suitable for use in earthquake-prone areas because it has high compressive strength and durability [6]. Geopolymer concrete was created to protect the environment from future hazards such as the dangers of gas emissions produced by burning cement because the material that is composed of geopolymer concrete is composed of the synthesis of non-organic natural materials through a polymerization process, which replaces the ordinary portland cement (OPC) which functions as a binder with environmentally friendly materials [7].…”

Concrete is a material that is widely used in the construction world. The production of Portland cement in concrete leads to CO2 emissions that have an impact on global warming. Geopolymer Concrete is an eco-friendly material because it does not use Portland cement. Geopolymer cement is made from waste materials such as fly ash (FA) by alkali activation. In geopolymer, sodium silicate is a commonly used activator that is produced commercially. In this study, rice husk ash (RHA) from agricultural waste was used as an activator for geopolymer cement. The objective of this study is to review the chemical component of FCA and RHA and, to examine the effect of RHA in geopolymer concrete mixed design on the compressive strength. The geopolymer concrete binder is using 12 M NaOH and Na2SiO3, with variations for RHA 0%, 5%, 7.5%, and 10%. The specimens were treated for 28 days, curing in a 70oC oven for 24 hours then curing at ambient temperature. The result shows that geopolymer concrete has a higher compressive strength compared to ordinary Portland cement (OPC) as much as a 5.9 MPa difference with geopolymer concrete of RHA10% of 25 MPa.
