Study On The Technology Of Disguising In The Aerated Concrete Block Walling

The Air Concrete Block has emerged as the ultimate building material with its unique combination of lightweight, heat-insulating and workability. However, when we adopt ordinary mortar to construct and plaster ash, due to The Air Concrete Block's unique cell structure and absorbing water propriety, There are still many problems, such as wall crack, big area of layer of plasterer ash crack and partially hollow drum, even according to present The Air Concrete Block construction standard, for the actual operation craft is so complicated that it is very difficult to guarantee each preface quality. We could reduce the probability of wall crack occurring with reasonable structure and technology, strict management, binding or releasing power and emergency, but we won't dispel quality sick unless we solve the form question of The Air Concrete block and mortar. Under the background, the paper is finding out a method to solve the question of The Air Concrete Block wall crack, with studying the behavior of The Air Concrete Block exclusive affiliate material (plastering ash mortar), and analyze how it match with The Air Concrete Block's characteristics.The paper summarized the apply situations and characteristics of The Air Concrete Block, and the studying situations of The Air Concrete Block's wall crack. In the terms of The Air Concrete Block material characteristics, ordinary mortar characteristics, constructing craft, we analyze the principle of The Air Concrete Block's wall crack feasibility of the air concrete block exclusive mortar research. According to each ingredients (water retaining admixture, polymer, inorganic mineral)'s effect to mortar's behaviors (water relativity, contractility, resisting wind ) in exclusive mortar's composite addition, we defines each ingredient's quantity scope, then defines the mix's through cross experiment. We compared the air concrete block exclusive mortar's behaviors such as water relativity, binding strength, shrinkage and others with ordinary mortar's ones, it turns out to be that there is much improve in farmer's behaviors such as water relativity, contractility, binding strength etc. it also shows that the air concrete block exclusive mortar can improve the wall crack of the air concrete block in a certain degree.
