High-performance concrete admixture in use of waste ceramic powder and implementing method thereof

Abstract

The invention discloses a high-performance concrete admixture in use of waste ceramic powder and an implementing method thereof. The high-performance concrete admixture is prepared by the following steps: utilizing waste ceramics as a main material and utilizing active seed crystals and a modified enhancer as auxiliary materials; performing modified treatment and high-temperature smelting on various materials, then putting into a cement mill to mill the materials to be pre-finished products with specific area of 300-450 m2 / kg, and finally, doping mixed fibers. The high-performance concrete admixture comprises the raw materials in parts by weight: 80-100 parts of waste ceramic powder, 6-9 parts of active seed crystal, 2-6 parts of modified enhancer and 5-10 parts of mixed fibers. By adopting mixed ceramic powder, density of cement mortar is effectively increased; strength of concrete is improved and durability of concrete is remarkably improved. Energy problems are solved, and meanwhile, an environmental protection purpose is considered; the high-performance concrete admixture has remarkable technical, economic and social benefits.

Description

technical field [0001] The invention belongs to building materials, and in particular relates to an admixture for preparing high-performance concrete and an implementation method thereof. Background technique [0002] Looking at the current research status of all new admixtures and the durability of concrete, the analysis from all angles is comprehensive and in place. Whether it is from the macroscopic physical and mechanical properties or the microscopic properties of the material itself, countless domestic and foreign scholars have conducted detailed research, discussion and analysis on concrete, including new concrete. The experimental research on ordinary concrete and conventional admixture concrete has been relatively mature, and it has a good theoretical and practical basis in terms of preparation technology and performance improvement. There are also many studies on new admixture concrete, but a systematic research summary is lacking. The research on a new type of a...
