为便于研究陶粒的膨胀过程,下面简要介轺一下测定陶粒膨胀系数及气体析出量的方法。一、膨胀系数陶粒的膨胀系数以粘土膨胀前后的体积比来表示,即: K=(V_2)/V_1式中:K——膨胀系数; V_1——泥球膨胀前的体积,cm~3; V_2——泥球膨胀后的体积,cm~3。用细砂求积法或水银求积仪来测定泥球体积,由于准确性较差和操作比较麻烦,得出的膨胀系数误差 In order to facilitate the study of the expansion process of ceramsite, the method of determining the expansion coefficient of ceramsite and the amount of gas evolution is briefly described below. First, the coefficient of expansion of the coefficient of expansion of ceramic particles to the volume before and after the expansion of the clay to represent, that is: K = (V_2) / V_1 where: K - expansion coefficient; V_1 - volume of mud ball before expansion, cm ~ 3 V_2——The volume of the ball after swelling, cm~3. Using a fine sand quadrature method or a mercury-hoistograph to determine the volume of the mud ball, due to poor accuracy and troublesome operation, the resulting expansion coefficient error
