Haydite aerated concrete block and method for manufacturing same

Abstract

The invention discloses a formula of a ceramic aggregate aerated concrete brick and a method for making the concrete brick. The compositions in portion by weight of the concrete brick are: 12 to 26 portions of cement, 26 to 46 portions of fly ash, 16 to 28 portions of ceramic aggregate, 2 to 6 portions of slag, 2 to 6 portions of cinder, 16 to 26 portions of water and 2 portions of addition agent, wherein the concrete matters in percentage by weight of the addition agent are: 10 to 18 percent of aluminum powder (a foaming agent), 20 to 45 percent of polycarboxylate (a water reducing agent), 15 to 35 percent of 1122 fly ash excitant and 20 to 50 percent of coagulant hardening accelerator in which calcium chloride and sodium sulfate compounds respectively occupies 50 percent. The concrete steps for making the ceramic aggregate aerated concrete brick are as follows: raw materials are weighed; the weighed raw materials are placed in a stirring machine to carry out stirring and mixing in advance; an addition agent is added in the stirring machine to carry out full stirring; a brick die is prepared, and stirred raw materials are cast in the brick die; initial set and forming are carried out; stripping is carried out; a water-proofing agent is sprinkled on a stripped brick; and natural curing is carried out. Moreover, the obtained brick has light dead weight, low density, high strength, low water absorption rate and excellent sound insulation performance and heat-shielding performance.

Description

Technical field: [0001] The invention belongs to building wall materials, in particular to a building ceramsite aerated concrete block and a manufacturing method thereof. Background technique: [0002] At present, there are many types and models of wall blocks for construction on the market, each of which has its own advantages and disadvantages. For example, fly ash aerated blocks and quartz sand aerated blocks, although their raw materials are easy to obtain The process is simple and the cost is low, but its compressive strength is low, and it has the disadvantages of moisture absorption and moisture resistance, the finish is easy to fall off, and it cannot be hung. It can only be used as an interior wall material, not an exterior wall material. However, the existing exterior wall material - clay brick, although it has high strength, its heat insulation, sound insulation, moisture resistance and other performances can not meet the requirements of modern living environment,...

Problems solved by technology

[0002] At present, there are many types and models of wall blocks for construction on the market, and each has its own advantages and disadvantages. For example, fly ash aerated blocks and quartz sand aerated blocks, although their raw materials are easy to obtain The process is simple and the cost is low, but its compressive strength is low, and it has the disadvantages of moisture absorption and moisture resistance, easy to fall off the finish, and cannot be hung. It can only be used as an interior wall material, not an exterior wall material.

However, the existing exterior wall material - clay brick, although it has high strength, its heat insulation, sound insulation, moisture resistance and other performances can not meet the requirements of modern living environment, and it destroys the ecology and wastes land resources, which has been compelled by the policy regulations, gradually prohibiting the use of
