一、引言 1972～1977年,我们进行了水泥土的研究。在室内试验的基础上,1974年在室外修建了水池、渠道等小型试验工程。1975～1977年,在红领巾水库下游北什轴公社用水泥土衬砌渠道2.4公里,应用基本成功,见图1。水泥土由土料、水泥和水按一定比例配制拌合、夯打或碾压而成。基本原材料是土料,一般用砂土、砂壤土和壤土。 I. Introduction 1972 ~ 1977, we conducted a study of cement soil. On the basis of laboratory tests, small-scale pilot projects such as ponds and channels were constructed outdoors in 1974. From 1975 to 1977, the northwest shaft commune in the lower reaches of Hongyujin Reservoir was lined with cement-soil 2.4 km and the application was basically successful. Cement soil from the soil, cement and water according to a certain percentage of mixing, ramming or rolling. The basic raw materials are soil materials, usually sand, sandy loam and loam.
