v.Termite hill clay

The chemical properties of calcined termite hill clay powder include the fact that the material is pozzolanic with the sum of SiO2 (38.82%), Al2O3 (23.98%), and Fe2O3 (11.68%) constituting 74.48% of the material, leading to the conclusion that termite hill clay powder calcined at the temperature of 650o C satisfied the requirement of ASTM C618 of a minimum of 70%. Moreover, classified as natural Pozzolana class N. It means, the material can produce the cementitious compound that has binding property upon reaction with calcium hydroxide gained from the hydration of cement. Therefore, calcined termite hill clay powder was found suitable to partially replace cement in the production of concrete. up to 11.3% by weight and it implies it can reduce the CO2 emission by 11.3% due to cement production and it will save the natural materials by the same percentages.
