Abstract:

In recent years, the cement industry of the Son La province has had a high growth rate, contributing to the economic restructuring of the province towards industrialization and modernization. Based on the synthetic results of geological documents show that the study area has limited mineral resources investigation. Therefore, to ensure stable cement production, it is necessary to discover new areas with reserves to meet good quality production as a cement addition. Basalt exploration results in the Pa Dong area show that weathering and semi-weathering basalt has good quality as a cement addition with the average contents of major oxides as SiO2 of 45, 98%, Al2O3 of 9.63%, MgO of 5.67%, SO3 of 0.025 %, the absorbance of lime is 73.15 mg CaO/g additive. Total of the reserve at the levels of 121+122 equal 4,776 thousand ton, in which the level 121 of 1,127 thousand ton, and level 122 of 3,649 thousand ton.
