Abstract

A concrete air-added heat preservation brick is prepared from, by weight, 115-125 parts of ordinary Portland cement, 100-110 parts of composite filler, 7-9 parts of reinforced filler, 7-8 parts of composite forming agent, 9-10 parts of additive and 55-62 parts of papermaking wastewater. The composite filler is prepared from coal ash, titanium nitride, metakaolin and ceramic polishing waste. The reinforced filler is prepared from polycrystal mullite cellucotton and chopped glass fiber. The composite forming agent is prepared from dioctyl sodium sulfosuccinate, alkyl polyglucoside and pentaerythritol stearate. The additive is prepared from ammonium polyphosphate, sodium dehydroacetate, pine tar and a polycarboxylates high performance water-reducing agent. The concrete air-added heat preservation brick has the advantages of quite outstanding high pressure resistance and high bending strength, and is good in heat preservation effect.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a concrete aerated heat insulating brick and a preparation method thereof. Background technique [0002] Selection of exterior wall materials When selecting exterior wall materials, attention should be paid to the load-bearing, heat preservation, moisture-proof and economic requirements of the exterior wall. Clay solid brick walls have the advantages of low price, strong heat storage capacity, good thermal stability, and certain moisture absorption and moisture dissipation effects. However, this kind of wall material is heavy and thick, and construction is time-consuming. The thermal insulation performance of the clay hollow brick wall is about twice that of the solid brick wall, the weight is 20-40% lighter, and the strength is also higher. Concrete hollow bricks have similar thermal insulation properties to hollow bricks. Lightweight aggregate concrete walls have t...
