Abstract

The invention discloses a hybrid fiber air-entrapping wall material and a preparation method thereof. The wall material is prepared from, by mass, 0.25-0.32% of hybrid fiber, 15-25% of quartz tail-sand, 35-50% of volcanic rock powder, 15-20% of cement, 8-11% of quick lime, 3-6% of flue gas desulfurization gypsum, 0.12-0.2% of composite foaming agent and 0.08-0.12% of foam stabilizer, wherein the ratio of water to material is 0.4-0.5%. The hybrid fiber air-entrapping wall material and the preparation method thereof have the advantages that the hybrid fiber formed by combining a polypropylene fiber with a carbon fiber is added into the air-entrapping concrete wall material, the strength of the air-entrapping wall material is greatly improved, the anti-cracking ability is strengthened, and the problem of missing edge off angle is overcome, in addition, the quartz tail-sand and waste gas volcanic rock stone are taken as siliceous materials to replace fly ash, the resource utilization of the waste is achieved, and the problems of the resource shortage and environmental pollution of the fly ash are solved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a hybrid fiber aerated wall material and a preparation method thereof. Background technique [0002] In current construction products, especially concrete, more and more fiber-reinforced materials are used, but there are not many studies on adding fibers to autoclaved air-entrained concrete. Air-entrained concrete is a lightweight silicate wall material with a porous structure. Its inherent weakness is that it is prone to cracks due to its brittleness, and its strength is generally low. People are also solving this problem in different ways. The addition of microfibers to the aerated wall material can improve its tensile strength, flexural strength, wear resistance, impact resistance, corrosion resistance, fatigue resistance, toughness, crack resistance, and explosion resistance. Excellent crack resistance and anti-deformation ability can greatly reduce the crack width of the c...
