Abstract :

The aim of this experiment is to utilize locally available industrial waste products to produce binder for concrete production in order to minimise Portland cement consumption. This is achieved by using alkali- activated binder known as geopolymer which is an embodiment of mineral polymers obtained from geochemistry. Four geopolymer concrete mixtures were designed using Fly ash and kaolin as source materials designated as MXX, MX1, MX2 and MX3 while sodium hydroxide and sodium silicate were used as alkali activators. Portland cement concrete with the same grade was also prepared to serve as control. Geopolymer concrete specimens were cured in oven at temperatures of 30 o C, 50 o C, 70 o C,100 o C and 120 o C respectively. Compressive strength of geopolymer concrete was determined and compared with that of OPC concrete. The results show that the compressive strengths of geopolymer concrete was much higher than that of OPC concrete. It was also discovered that the strength increased with increasing temperature and curing time.
