Abstract

The invention discloses a method for preparing a constructional composite mineral admixture. The method is characterized by comprising the following raw materials in parts by weight: 45-50 parts of aluminum oxide clinker, 15-20 parts of calcined alunite, 5-10 parts of zinc sulfate, 25-30 parts of dickite, 25-30 parts of attapulgite clay, 20-25 parts of pulverized fuel gas, 1-5 parts of zeolite powder, 2-4 parts of diatomaceous earth, 2-5 parts of bentonite, 1-2 parts of methylcellulose, 0.5-1 part of sodium sulfite, 0.5-1 part of quicklime, 0.3-0.5 part of sodium carbonate, 0.5-1 part of gypsum and 0.2-1 part of sodium silicate. The constructional composite mineral admixture has the function of effectively resisting water, humidity, swelling, cracking, seepage and the like, and does not rust or corrode reinforcing steel bars.

Description

technical field [0001] The invention relates to a preparation method of a composite mineral admixture for construction, which belongs to the field of construction 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 a common problem in engineering Alkali-aggregate reaction also accelerates the corrosion of steel bars, resulting in concrete cracking and water seepage. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a method f...
