Anti-crack mortar
The invention discloses anti-crack mortar which is prepared from, by weight, 60% of yellow sand, 10% of coal ash, 4% of modified bentonite, 3% of modified glass fibers, 8% of rock flour, 3% of quick lime, 6% of cement, 0.5% of aluminum powder, 4.5% of redispersible latex powder and 1% of water reducing agents. Compared with an existing autoclaved aerated brick manufacturing technology, the anti-crack mortar is simple in production process and low in cost, the prepared mortar is good in strength, low in heat conductivity coefficient and quite good in anti-crack effect, energy is saved, environment-friendliness is achieved, the requirements of construction projects are met, and the environmental protection requirement is met. According to the anti-crack mortar, the modified bentonite andand the modified glass fibers are added, the stability of the mortar is further improved, and the impact-resistance strength is greatly improved; adhesion to a wall and sagging resistance are enhanced, construction efficiency is improved, the phenomena of cracking and hollowing are avoided in the wall use process, and the strength of the wall is greatly improved.
