Summary
Properties and application of bentonite Co Dinh – Thanh Hoa and Tam Bo – Lam Dong provinces
Presented research results: the properties of bentonite of Co Dinh (Thanh Hoa) and Tam Bo (Lam Dong) including particle size, mineralogical composition, chemical composition, soil plasticity, soil swelling and soil water holding capacity. In comparison with bentonite of Tam Bo, bentonite of Co Dinh is better in term of clay content, CEC, soil plasticity and soil swelling. When bentonite is mixed with the rate of 10-20 t/ha with degraded grey soils, sandy soils and ferralitic soils, properties of those soils have been improved in terms of soil water holding capacity, especially bentonite od Co Dinh.
