摘要
起泡剂是制备气泡混合轻质土的关键，通过研制复配起泡剂，选用粘性土作为原料土，制作气泡混合轻质土并对其容重及强度性能进行试验研究。通过试验结果的综合分析，提出了该气泡混合轻质土容重及强度指标随各影响因素的变化规律。试验中所有制备试样的容重在0．591～1．124g／cm^3之间、强度在300～800kPa之间变化，能够达到实际工程应用的要求。
Foaming agent is the most important component to preparation of bubble mixed light soil. In this paper the bubble mixed light soil was prepared by composite foaming agent with clay soil as raw material and its unit weight and strength properties were tested. By analyzing trial data, it puts forward the regularities of variation of unit weight and strength vs. influence faetors. It was diseovered that for all trial data, the unit weight in range of 0. 591-1. 124g/cm^3 and the strength in range of 300-800kPa, which can be feasible to engineering construetion.
