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 geo-polymer 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
meta-kaolin. The compressive strength of the three types geopolymer concrete
were tested and compared to each other. The cylin-der with size of (70 mm x 140
mm) is used in this experimental program. The curing after casting the cylinder
uses room tem-perature. 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.
