Thermal insulation lightweight concrete material and preparation method thereof
The invention relates to the technical field of building materials, in particular to a thermal insulation lightweight concrete material, which comprises water, cement, fly ash, sand, calcium hydroxide, waste rubber particles, asphalt fibers and auxiliaries. The preparation method comprises the following steps: adding the cement, the fly ash, the sand, the calcium hydroxide and the water into the pre-dispersed asphalt fiber according to the weight part ratio, uniformly stirring and dispersing, then adding the pre-plasticized waste rubber particles, uniformly dispersing to obtain mixed slurry, and then adding the other auxiliaries, and uniformly dispersing to obtain a concrete material precursor; pouring the concrete material precursor into a mold for steam curing, performing normal-temperature curing after demolding, and obtaining a finished product of the heat-preservation lightweight concrete material. The problem that in the prior art, a concrete material is poor in heat preservation effect is solved. The thermal insulation lightweight concrete material has the advantages of light weight and thermal insulation.
本发明涉及建筑材料技术领域，特别是涉及一种保温轻质混凝土材料，包括：水，水泥，粉煤灰，砂子，氢氧化钙，废橡胶颗粒，沥青纤维，助剂。制备方法包括：按照上述重量份数的配比将水泥、粉煤灰、砂子、氢氧化钙和水加入预分散的沥青纤维中，搅拌分散均匀，再加入预增塑的废橡胶颗粒分散均匀得到混合浆体，再加入其余助剂分散均匀，即得混凝土材料前驱体；将混凝土材料前驱体浇筑到模具中进行蒸汽养护，脱模后进行常温养护，即得保温轻质混凝土材料成品。本发明解决现有技术中混凝土材料的保温效果差的问题。上述保温轻质混凝土材料具有轻质保温的优点。
