Thermal insulation lightweight aggregate concrete and preparation method thereof
The invention discloses thermal-insulation lightweight aggregate concrete and a preparation method thereof. The thermal-insulation lightweight aggregate concrete is prepared from the following raw materials in parts by weight: 380 to 463 parts of ordinary Portland cement, 20 to 53 parts of silicon powder, 170 to 187 parts of shale ceramsite, 30 to 100 parts of floating beads, 20 to 22 parts of hydrophilic modified polystyrene particles and 160 to 200 parts of water. The polystyrene particles are modified to improve the bonding capacity of the polystyrene particles and cement paste, and the ratio of the ceramsite to the floating beads is adjusted to obtain the high-strength light-weight thermal-insulation light aggregate concrete, the dry density of the obtained thermal-insulation light aggregate concrete can be smaller than 800 kg/m < 3 >, the compressive strength can reach 5 MPa or above, the heat conductivity coefficient is 0.18-0.24 W/(m.K), and the thermal-insulation light aggregate concrete has the advantages that the thermal-insulation light aggregate concrete is high in strength and light in weight; good mechanical property and thermal insulation property are realized.
本发明公开了一种保温轻集料混凝土及其制备方法。本发明保温轻集料混凝土，包括以下重量份数的原料：普通硅酸盐水泥380‑463份，硅粉20‑53份，页岩陶粒170‑187份，漂珠30‑100份，亲水改性聚苯乙烯颗粒20‑22份，水160‑200份。本发明通过对聚苯乙烯颗粒进行改性处理，提高其与水泥浆体的粘结能力，并通过调整陶粒和漂珠的配比，得到一种高强轻质的保温轻集料混凝土，其中，所得的保温轻集料混凝土干密度可小于800kg/m3，抗压强度可达到5MPa以上，导热系数在0.18‑0.24W/(m·K)，具有良好的力学性能、保温性能。
