Load-bearing and heat-insulation concrete taking ettringite colloid as template agent and preparation method for load-bearing and heat-insulation concrete
The invention relates to load-bearing and heat-insulation concrete and a preparation method for the load-bearing and heat-insulation concrete and particularly relates to novel concrete, which has a uniform micropore structure and simultaneously has load-bearing capacity and a heat insulation function, prepared through forming an aqueous-phase uniform three-dimensional-network micropore structure by taking ettringite colloid as a template agent and adding a cementing glue material, fine aggregates, coarse aggregates, additives and admixtures. The load-bearing and heat-insulation concrete disclosed by the invention has the characteristics of light weight, high strength and low coefficient of thermal conductivity, can be used for preforming bricks, building blocks and sheet materials or components such as assembly-type stairs, wallboards, floor slabs, balcony slabs and roof panels in plant, can also be subjected to cast-in-place at a construction field site and is compatible with an aerated concrete production process, a foamed concrete production process and an ordinary concrete preforming production process at present, so that the transformation and upgrading of the traditional concrete industries are facilitated, and the load-bearing and heat-insulation concrete has remarkable practical significance in promoting the industrialization of Chinese residence and the development of environment-friendly building concrete materials.
