Abstract

The invention discloses green high-performance polymer cement waterproof mortar adopting aeolian sand and a preparation method of the waterproof mortar. The mortar is prepared from components as follows: 34-36 parts of cement, 29-32 parts of quartz sand, 23-26 parts of the aeolian sand, 8-10 parts of latex powder, 0.2-0.6 parts of fibers, 0.1-0.2 parts of a water reducer and 0.2-0.4 parts of a defoaming agent. The aeolian sand is utilized to equivalently replace part of the quartz sand, so that the green high-performance polymer cement waterproof mortar with properties including liquidity, caking property, impermeability and the like better than those of common polymer cement waterproof mortar is prepared. The problem of shortage of existing building raw materials is solved, the problem ofincreasingly serious desertization at present can be solved, the aeolian sand as a waste resource is sufficiently utilized, waste is changed into wealth, and sustainable development of the building waterproofing industry can be promoted.

Description

Technical field [0001] The invention belongs to the field of building waterproof materials, and particularly relates to a green high-performance polymer cement waterproof mortar using aeolian sand and a preparation method thereof. Background technique [0002] Due to the increasing complexity of construction projects, higher requirements are also put forward for building waterproofing. In recent years, the frequent occurrence of accidents such as leakage of external walls, bulging of tiles, and injuries to people due to problems with waterproof materials have attracted people's attention. Therefore, improving and improving the performance of waterproof materials through material design and optimization is an important problem to be solved urgently. Traditional waterproof materials have experienced long-term development, and now the new type of waterproof material, green high-performance polymer cement waterproof mortar, is the latest development trend in the building waterproofi...
