Coal gangue concrete and preparing method thereof
The invention relates to a concrete product with coal gangue aggregates as main raw materials and a preparing method thereof, in particular to the method for preparing the concrete by calcining coal gangue manually, and belongs to the technical field of concrete materials, wherein the coal gangue is manually-calcined coal gangue, and the calcining temperature of the coal gangue ranges from 1100 DEG C to 1200 DEG C. The coal gangue is prepared by evenly mixing and stirring, by weight, 40%-50% of manually-calcined coal gangue, 15%-23% of cement, 25%-28% of medium sand and 5%-12% of water. According to the coal gangue concrete and the preparing method, the advantages of being high in cylinder compressive strength, light in weight, low in heat conductivity coefficient, capable of saving energy, free of radioactivity and the like of the coal gangue are utilized, waste is turned into wealth, and the produced concrete can be cast in situ, can be prefabricated and can be used for blending the coal gangue concrete of a high-strength structure; the process is simple, no new device needs to be built, and the self-ignition coal gangue can be calcined through an existing device; the coal gangue concrete and the preparing method thereof have remarkable economic and social benefits on the aspects of saving the land, saving the energy, utilizing the waste, protecting the environment and the like, accord with the national industrial policy and are easy to apply and popularize.
