Geological surveys, mineral prospecting and exploitation show that Thanh Liêm area, Hà Nam province has great potential for limestone and limited reserve of clay while both limestone and clay can be used as inputs in cement production. Therefore, it is necessary to study geological characteristics, quality features of and the possibility to apply clay in Thanh Liêm area in order to provide a material for cement factories in Hà Nam province. Khe Non, which is located at Thanh Hương, Thanh Lưu and Liêm Sơn communes of Thanh Liêm, Hà Nam province, is an area with clay potential for the production of cement. Based on the results of existing prospecting and exploration researches and documents, this paper discusses about the quality features of clay at Khe Non and the possibility to mix it with other materials in cement production at lab scale. The result of this study provides important foundation for planning exploitation well as rational and efficient use of this resource in the production of cement in the area.
