At present, the source of puzoolan (natural, artificial) is plentiful, it is used in the manufacture of Portland cement puzoolan or replace a part of cement in the construction of roller compacted. v.v… However, the use of puzoolan as a binder, partial replacement of cement to strengthen the soil in place has not been much research.This paper analyzes the chemical composition of minerals, the lime sorption of natural puzolan extracted in K'rông Nô district of Dak Nong province to evaluate their applicability in soil reinforcement. Comparison of the results of the sample analysis at two locations in the study area according to current standards shows that the ability to apply natural puzoolan is relatively high in the land consolidation in place.
