复合水泥土抗渗性能的实验研究
Study on Impervious Performance of Cement-soil
摘要
Abstract
Cement-soil technique has been widely used in roads, construction, water conservancy and other fields. This paper studies the effects of permeability coefficient by changing the quantity of cement-soil content, age, fly ash, lime in Hetao area of Inner Mongolia, and analyzes the change of cement-soil microstructure by the electron microscope on permeability coefficient of the cement-soil. The result shows that the permeability coefficient is small if the quantity of cement content is large and the age is growth. Only mixing fly ash on content does little affect on the permeability coefficient of cement-soil, but the addition of lime can stimulate the fly ash clouds of ash role, generating insoluble in water hydration calcium silicate. This paper concludes good anti-permeability proportion focus on silty clay in He Tao area of Inner Mongolia. The proportion is water: cement: fly ash: lime: silty clay = 1.45: 1.00: 0. 15: 0. 0375: 7. 3625. This ratio compares fly ash cement-soil decreasing permeability coefficient more than 50%.关键词
