Soil Stabilization Methods Used for Stabilizing Soil
Soil stabilization is used to increase the unit weight of the soil. It helps to decrease the void ratio of the soil. Stabilization of soil increases the shear strength of soil. Soil Stabilization Methods. Different soil stabilization techniques are used all over the world. These soil stabilization methods are listed below. Cement stabilization
Cement Stabilization of Soil - Civil Engineers Forum
by Anthony Hock. Cement stabilization of soil is done by mixing pulverized soil and Portland cement with water and compacting the mix to attain a strong material. The material obtained by mixing soil and cement is known as soil-cement. The soil cement becomes a hard and durable structural material as the cement hydrates and develops strength.
Chemical Soil Stabilization - Civil Engineers Forum
Disadvantages of Chemical Stabilization. The disadvantages are-This method of stabilization is relatively expensive than the other stabilization methods. The treated soil may loose strength when exposed to air or ground water. Require extra experienced labor. In chemical soil stabilization, chemical should not be used directly to the surface.
Plane Surveying | Methods of Surveying - Civil Engineers Forum
2015年11月2日 · Plane surveying is the survey in which the earth surface is assumed to be plane and the curvature of the earth is ignored. The plane surveys extend only over small areas and the lines connecting any two points on the surface of the earth are treated as straight lines and the angles between such lines are taken as plane angles.
