Comparative Study of the Mechanical and Chemical Characteristics of GCK and ZIJI Cements

This work talks about the comparative study of the mechanical and chemical characteristics of ZIJIN and GCK cements produced and used in the great KATANGA. Indeed, the field of construction is in full development in this region; thus, the production of good quality cement in this part of the country will allow users to trust these two cement industries. In order to properly conduct this study, we carried out several chemical and mechanical analyzes on ZIJIN and GCK cements; the latter were carried out on bricks made from a mixture of cements associated with a type of material (crushed sand, fine sand and ferruginous laterite) poured into 16x32 test specimens. After 28 days of maturation for the mortar, we conducted bending and compression analysis tests using a GLP equipment type device (cube press). The main objective of these tests is to define the resistance of the brick obtained from a purely chemical mixture. We obtained varying compressive strengths for different mixtures at 28 days, illustrating the mechanical performance of each cement type when paired with specific aggregates.
