Reactivity of rice husk ash

James, Jose / Subba Rao, M.

AbstractEffect of lime:silica ratio on the kinetics of the reaction of silica with saturated lime has been investigated. Below C/S=0.65 the reaction does not proceed to completion and even in the presence of a large excess of silica only 90% lime is consumed. A parameter, lime reactivity index, has been defined to quantity the reactive silica present in rice husk ash. The product of the reaction between rice husk ash and saturated lime is a calcium hydrosilicate, CSH(I)^∗∗∗∗Symbols used; C=CaO, S=SiO2, H=H2O.. The fibrilar structure and the hollow tubular morphology of the fibres of CSH, have been explained by a growth mechanism, where the driving force is osmotic pressure.
