Utilization of low grade kaolinite waste from rock mining as fine aggregate for construction precast energy conservation building

Abstract

The research aims to study and develop the Kaolinite mixed with cement powder for the mass wall. The Kaolinite development process to improve the characteristics. The Kaolinite mixed ratios are 10%, 20%, 30% and 40% and the result indicated that the experiment mortar-mix ratio at 0:8:2.75:0.2:0.05:0.04:0.5 of cement powder, sand, Kaolinite, limestone, superplasticised and clean water compared to No MK control sample covered ASTM standard in tensile strength more than 100 ksc, compressive strength of MK20% with superplasticised at 434 ksc. The water absorption values under the standard passed
