Enhanced low heat conductivity coefficient type aerated concrete and preparation method thereof
The invention relates to the technical field of concrete preparation, in particular to reinforced low-heat-conductivity-coefficient type aerated concrete and a preparation method of the reinforced low-heat-conductivity-coefficient type aerated concrete. The high-performance water reducer comprises the following components in parts by weight: 55-80 parts of quartz sand, 10-20 parts of lime, 2-5 parts of desulfurized gypsum, 10-15 parts of cement, 0.2-0.4 part of aluminum powder, 1-1.5 parts of basalt alkali-resistant glass composite fiber powder, 3-8 parts of montmorillonite modified core-shell structure vinyl versatate polymer emulsion and 0.2-0.3 part of 40% polycarboxylic acid water reducer water, and the ratio of water to material can be reduced to 0.3-0.5 by adding a proper amount of polycarboxylic acid high-performance water reducer. Montmorillonite-modified core-shell structure vinyl versatate polymer emulsion and basalt alkali-resistant glass composite fiber powder are added to prepare the composite material with relatively high compressive bearing resistance, external constraint tensile stress, impact load effect, temperature material strain force, high temperature resistance and high tensile strength. Meanwhile, the aerated concrete has relatively good mechanical strength, freezing resistance and crack resistance in severe environments such as freeze-thaw resistance and the like.
