Compression Characteristics Of Silt-Bentonite Mixtures In Liners
Subject area: Science,Engineering and Technology · Area of research: Civil Engineering
Abstract
For liners, strength is necessary in achieving the durability and preventing from the mechanical shocks occurred. The silt and bentonite are mixed together and various proportions of the mixtures are studied for the compactions characteristics. If the bentonite and soil mixed together in the preparation of liner, the waterproofing capacity of bentonite helps to decrease the permeability of the mix proportion and also fill the pores of the mix. The soil acts as a sealant when the strength reduced in the mix. Obtained results from the different mix proportions shows that up to the weight of 20% bentonite the dry density decreases and also the increase in moisture content observed as per the increase in bentonite.
