Abstract

The invention discloses a high-performance building material. The high-performance building material comprises the following raw materials in parts by weight: 62-95 parts of cement, 45-56 parts of stone-waste artificial sand, 12-20 parts of kaolin, 8-14 parts of montmorillonite, 3-6 parts of water reducer, 9-16 parts of mica, 7-13 parts of glycerol, 3-5 parts of graphene oxide, 6-10 parts of basalt fibers, 2-4 parts of sodium fluoride, 6-10 parts of beta-caryophyllene-maleic anhydride copolymer, 16-25 parts of calcium bicarbonate, 4-8 parts of sulfuric acid and 52-78 parts of water. Compression strength and folding strength of mortar test pieces prepared by adopting the building material disclosed by the invention are obviously superior to those of mortar test pieces prepared in the priorart and are separately improved by at least 49.59% and 82.44%; and the high-performance building material can be used for solving the problems of the existing building materials that prepared mortar test pieces are not high enough in compression strength and folding strength and cannot meet the requirements of people on buildings.

Description

technical field [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a high-performance building material and a preparation method thereof. Background technique [0002] Cement mortar, also known as mortar, is a building material mixed with inorganic cementitious material, fine aggregate and water in proportion. It is mostly used in masonry and plastering projects in building construction to achieve building structure and surface protection and decoration. Traditional mortar materials generally include cement, water, stone waste, artificial sand, etc. In order to improve the strength and crack resistance of the building structure mortar layer, gypsum, lime plaster or fibrous reinforcing materials can often be added. The surface of buildings made of cement mortar can maintain a certain strength in the early stage, but as time goes on, it is prone to cracking, leakage, peeling, etc. Studies have shown that moderate...
