Mechanism of Enzyme Stabilization The organic cations also reduce the thickness of the electrical double layer. This allows enzyme treated soils to be compacted more tightly together. Enzyme promotes the development of cementatious compounds using the following, general reaction: H2o + clay Enzyme Calcium Silicate Hydrates
Net Effect of Enzyme • Film of adsorbed water is greatly reduced. • The soil particles acquire a tendency to agglomerate • As a result of relative movement , the soil get condensed which in turn reduces the swelling capacity
