Abstract

Concrete is one of the construction materials that have been commonly used for the construction of buildings, bridges, roads and so forth. The need for concrete will increase in line with the increasing need of basic human facilities and infrastructures. Therefore, the production of cement as a binder of concrete increases as well. In the process of cement production occurs a process of a huge amount of CO2 release into the atmosphere and then damage the environment which among them cause global warming. To overcome these problems it’s necessary to find another material as a substitute for cement. Geopolymer concrete is an alternative to substitute concrete that uses cement. Geopolymer concrete is made without the use of cement as a concrete binder, and instead, using sinabung ash which is rich in silica and alumina and can react with alkaline liquids to produce a binder. In this research, the flexure strength of concrete is tested to a number of samples in the form of 15x15x60 cm3 block with curing time variation of 4 hours, 8 hours, 12 hours and 24 hours at 60oC temperature by using oven. From the results, it’s obtained that the graph of flexure strength value increases with the length of curing time. Maximum flexure strength occurs at 24 hours curing time.
