CEMENT COMPOSITION CONTAINING DUNE SAND AND LIMESTONE POWDER, CONCRETE PRODUCTS AND METHOD FOR MAKING CONCRETE PRODUCTS |
摘要 |
A raw batch composition for concrete or concrete wherein the raw batch composition comprises Portland cement of about 15 wgt. % to about 45 wgt. % and dune sand preferably red dune sand is present in an amount of about 40 wgt. %. The dune sand has a particle size of less than or equal to 45 microns. The composition also includes limestone powder ranging from about 15 wgt. % to 45 wgt. % with particle sizes less than or equal to 45 microns to form a base material. To this base material suitable amounts of fine aggregate, coarse aggregate, water and superplasticizer are added. A method for producing a cast concrete product having a compressive strength of between 62 MPa and 90 MPa is disclosed. The method comprises a step of providing Portland cement, dune sand and limestone powder. |
