The Compressive Strength Of Geopolymer Concrete Made With Baggase Ash And Metakaolin

Abstract

Geopolymer concrete becomes popular and extensively developed material because this concrete is a friendly environmental material. Generally, material synthesized from geological material or by product material used as based material for geopolymer concrete. This paper present the experimental program of geopolymer concrete with based material of baggase-ash and metakaolin. The baggase-ash is the waste material of sugar mill, while metakaolin is the geological material. Three types of geopolymer concrete were made in this experimental program. The first is geopolymer concrete based on baggase-ash. The second is geopolymer concrete based on metakaolin. And the third is the one based on the mixture of baggase-ash and metakaolin. The compressive strength of the three types geopolymer concrete were tested and compared to each other. The cylinder with size of (70 mm x 140 mm) is used in this experimental program. The curing after casting the cylinder uses room temperature. The results show that the compressive strength of the three types of geopolymer concrete generally are very low. However, geopolymer concrete based on the mixture of baggase-ash with metakaolin gives the highest compressive strength compares to others and can be developed for future research.
