Preparation method of binding material mix

Abstract

The invention discloses a method for preparing a cementing material mix of taking an alumina clinker as a primary raw material. The method for preparing the cementing material mix of taking the alumina clinker as the primary raw material is characterized by comprising the following raw materials (in parts by weight): 20-25 parts of alumina clinker, 15-20 parts of calcined alunite, 7-10 parts of zinc sulfate, 5-8 parts of dickite, 5-10 parts of attapulgite clay, 5-10 parts of fly ashes, 1-5 parts of zeolite powder, 2-4 parts of kieselguhr, 2-5 parts of bentonite, 1-2 parts of methylcellulose, 0.5-1 part of sodium sulfite, 0.5-1 part of quick lime, 0.2-0.5 parts of sodium tripolyphosphate, 0.2-0.7 parts of sodium borate and 0.2-0.8 parts of calcium chloride. The cementing material mix of taking the alumina clinker as the primary raw material disclosed by the invention has the functions of efficient water resistance, moisture resistance, expansion, crack resistance, permeability resistance and the like, and is free of corrosive action on a reinforcing steel bar.

Description

technical field [0001] The invention relates to a preparation method of a cementitious material mixture, in particular to a preparation method of a cementitious material mixture with alumina clinker as the main raw material, and belongs to the field of building material manufacturing. Background technique [0002] During the project, many building basements, roofs, roads, and bridges could not reach the designed service life, and some projects were severely damaged after only a few years of use and had to be repaired. The main reason is that the current waterproof materials and concrete Agents generally contain Cl-, K+ ions too heavy, when added to concrete, react with active silica in concrete to form alkali silicate gel and cause concrete expansion and cracking, which is the common alkali bone in engineering Material reaction, while accelerating the corrosion of steel bars, resulting in concrete cracking and water seepage.
