Non-autoclaved aerated concrete block manufactured from building slurry and manufacturing method thereof

Abstract

The invention discloses a non-autoclaved aerated concrete block manufactured from building slurry and a manufacturing method thereof, belonging to the technical field of building materials. The block comprises the following components in percentage by weight: 30%-45% of dry weight building slurry, 25%-40% of cement, 10%-25% of lime, 15%-30% of coal ash, 2%-8% of plaster and the balance being a foaming agent. The manufacturing method comprises the following steps of weighing each component and water; firstly, preparing an aluminum powder paste solution, then uniformly mixing the other components with the aluminum powder paste solution, and pouring the mixture into a mold; and carrying out delaying-curing hot cell maintenance, demolding, cutting and stacking maintenance so as to prepare the non-autoclaved aerated concrete block manufactured from the building slurry. According to the manufacturing method, the waste building slurry is utilized for manufacturing the non-autoclaved aerated concrete block, the energy-saving and environment-friendly effects are achieved, waste materials are recycled, and a good social benefit is achieved; the strength of the produced block is high, the block does not need to be autoclaved, the cost is low, and three wastes are not generated during a production process.

Description

Technical field:

[0001] The invention relates to the technical field of building materials, in particular to a non-steamed aerated concrete block made of building mud and a manufacturing method thereof. Background technique:

[0002] In the construction process of construction projects, the waste construction mud has a large amount, various types, and complex chemical components, so it is difficult to deal with. The current treatment methods are relatively backward and the treatment cost is also high. Therefore, construction mud has become a hazard to the natural ecological environment. One of the important sources of pollution. Since these substances are not easy to undergo natural biodegradation under natural conditions, they will cause varying degrees of impact and damage to the natural ecological environment under corresponding conditions. If the waste mud is stored or buried for a long time without treatment, some harmful substances will pollute the soil, surface water...
