process for the production of cement, clay gu00e9opolymu00e8re from tunisia

摘要

the invention relates to a method for preparing a cementitious material (gu00e9opolymu00e8re) at room temperature, which allows a very high mechanical strength and stability over time. compared to portland cement product is the gu00e9opolymu00e8re synthesis in the preservation of the environment (green cement.the production process includes: (1) preparing and mixing a natural clay and calcined (between 600 and 800 degrees c) with a basic solution of moh (m is k + or na +) and sodium metasilicate (nau2082 sio3.5h2o). (2) to perform the molding of a fresh product in standard moulds. 3) to the mixture in the mold is stabilized and harden.(4) after a period of time (14 days and 28 days), the conventional engineering test shows that the product has a high compressive strength. 40mpa.
