An investigation of Rice husk ash Pozzolan as a supplement in cement for building applications was carried out. A controlled burning of rice husk ash (RHA) at 5000C produced amorphous Silica (SiO2). The rice husk ash (RHA) was substituted for cement in proportions of 0%, 5%, 10%, 20% and 30% of concrete. The concrete was cured for 7 days, 14 days, 21 days and 28 days respectively.
Chemical admixtures are the ingredients in concrete other than portland cement, water, and aggregate that are added to the mix immediately before or during mixing.
The use of superplasticizers does not significantly affect surface tension of water and does not entrain a significant amount of air. The main disadvantage of superplasticizer usage is loss of workability as a result of rapid slump loss and incompatibility of cement and superplasticizers.

Cement and silica fume were preblended in dry form while the superplasticizer was dissolved in the mixing water. Within 30 seconds, the dry blend was poured into the water containing the superplasticizer while the mixer was stirring at 18,000 rpm. After this, mixing was continued for 30 seconds at 22,000 rpm.
The most important property of a superplasticizer is its ability of dispersing the cement particles. Electron microscopic examination reveals that in water suspensions of cement, large irregular agglomerates of cement particles form. By the addition of a superplasticizer, the material is dispersed into small particles.
