Thermal insulation type concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses heat preservation and insulation type concrete and a preparation method thereof. The heat preservation and heat insulation type concrete is obtained after a concrete mixture is subjected to molding and curing, and the concrete mixture is prepared from the following components in parts by weight: 620 to 640 parts of coarse aggregate, 460 to 480 parts of modified ceramsite, 760 to 800 parts of fine aggregate, 288 to 306 parts of Portland cement, 32 to 34 parts of fly ash, 140 to 150 parts of mixing water, 8.2 to 8.6 parts of dodecanol and 3.2 to 3.4 parts of polycarboxylate superplasticizer. The modified ceramsite is sintered ceramsite of which the surface is grafted with sulfonic groups, the sintered ceramsite is obtained by calcining, cooling and crushing a blank, and the blank comprises the components of building residue soil and sludge. According to the invention, the electrostatic adsorption of the polycarboxylate superplasticizer on the surface of the modified ceramsite is reduced, the binding degree between the modified ceramsite and cement paste is enhanced, and the strength performance of the heat-preservation and heat-insulation concrete is improved.
本申请涉及混凝土技术领域，具体公开了一种保温隔热型混凝土及其制备方法。所述保温隔热型混凝土由混凝土拌和物经过入模成型和养护后得到，所述混凝土拌和物包括如下重量份的组分：粗骨料620‑640份，改性陶粒460‑480份，细骨料760‑800份，硅酸盐水泥288‑306份，粉煤灰32‑34份，拌和用水140‑150份，十二醇8.2‑8.6份，聚羧酸减水剂3.2‑3.4份，所述改性陶粒为表面接枝有磺酸基的烧结陶粒，所述烧结陶粒由坯料经过煅烧、降温和破碎后得到，所述坯料的组分包括建筑渣土和污泥。本申请减少了聚羧酸减水剂在改性陶粒表面的静电吸附，并且增强了改性陶粒与水泥浆体之间的结合度，提高了保温隔热型混凝土的强度性能。
