Embodiment 1

[0023] Embodiment 1: the percentage by weight is: dry weight construction mud 31.0%, cement 25.0%, lime 15.0%, fly ash 25.0%, gypsum 4.0%, each component of the aluminum powder of 0.0008% weighs, then takes by weighing water, The weight of water is 55% of the total weight of the above dry powder materials; mix aluminum powder and water evenly to prepare an aluminum powder paste solution, and then mix construction mud, cement, lime, fly ash, and gypsum with the prepared aluminum powder paste solution Evenly, pour it into the non-steaming aerated concrete block mold; after 4 hours of curing in a static heating chamber, demoulding and cutting, stacking and curing for 28 days, the non-steaming aerated concrete block made of construction mud is obtained. The performance indicators are shown in Table 1.

Embodiment 2

[0024] Embodiment 2: the percentage by weight is: dry weight construction mud 30.0%, cement 30.0%, lime 15.0%, fly ash 20.0%, gypsum 5.0%, each component of the aluminum powder of 0.0007% is weighed, then takes by weighing water, The weight of water is 63% of the total weight of the above dry powder materials; mix aluminum powder and water evenly to prepare an aluminum powder paste solution, and then mix construction mud, cement, lime, fly ash, and gypsum with the prepared aluminum powder paste solution Evenly, pour it into the non-steaming aerated concrete block mold; after 4 hours of curing in a static heating chamber, demoulding and cutting, stacking and curing for 28 days, the non-steaming aerated concrete block made of construction mud is obtained. The performance indicators are shown in Table 1.

Embodiment 3

[0025] Embodiment 3: the percentage by weight is: dry weight construction mud 39.0%, cement 35.0%, lime 10.0%, fly ash 10.0%, gypsum 6.0%, each component of the aluminum powder of 0.0007% is weighed, then takes by weighing water, The weight of water is 68% of the total weight of the above dry powder materials; mix aluminum powder and water evenly to prepare an aluminum powder paste solution, and then mix construction mud, cement, lime, fly ash, and gypsum with the prepared aluminum powder paste solution Evenly, pour it into the non-steaming aerated concrete block mold; after 4 hours of curing in a static heating chamber, demoulding and cutting, stacking and curing for 28 days, the non-steaming aerated concrete block made of construction mud is obtained. The performance indicators are shown in Table 1.

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...
