Properties of Cement Mortar with Different Blending Amount of Rich Husk Ash (RHA)

CODEN: JTEVAB

Abstract

The morphology of rice husk ash (RHA) samples obtained at 400°C in a vertical high temperature furnace was characterized by scanning electron microscopy, and the effect of RHA on the mechanical behavior of cement mortar was studied. The RHA sample is slightly grey in color and there are some black particles. RHA samples have many sheets that are vertically and horizontally interlaced. The effect of RHA on the compressive and flexural strengths test for cement mortar has been investigated. The water absorption, mortar consistency, dry bulk density, and water permeability were tested. The compressive and flexural strengths decreased with the replacement of RHA. The mortar consistency improved, and water absorption increased. The dry bulk density of cement mortar decreased, and the water permeability increased. Because RHA is a resource containing properties that have the potential for categorizing it as waste, the comprehensive utilization of RHA is significant for improving environmental protection and gaining economic benefits.
