摘要：

In order to study the feasibility of preparing cement particle board by compounding silicate and rice straw shavings, this paper explored their compatibility by detecting the heat of hydration of both by HPLC and characterized by FTIR, SEM and XRD. The results suggested that rice straw contained a certain amount of sugars soluble in water as well as organic carboxylic acids, having toxic effects on the hydration of silicate cement and could retard the hydration reaction of silicate cement. The addition of rice straw would inhibit the generation...
