摘要
以磐石膨润土原矿为原料,用挤压钠化法对钙基膨润土进行改型,本次实验钠化剂分别采用Na2CO3、NaCl,结果表明：以Na2CO3的用量为3%,土含水量30%-35%,挤压一次,陈化时间在3-7天进行钠化改型,效果显著。
Panshi bentonite ore as raw material,modified calcium bentonite with extrusion sodium method.In this experiment,respectively use Na2CO3 and NaCl as sodium agent,results show that：the amount of Na2CO3 was 3%,soil moisture content 30%-35%,extrusion once,sodium modified in aged time 3-7 days,which has significant effect.
