Thermal insulation concrete block and preparation method thereof
The invention relates to the field of concrete blocks, and particularly discloses a thermal insulation concrete block and a preparation method thereof. The thermal insulation concrete block comprises the following components in parts by weight: 100-200 parts of cement; 40 to 70 parts of coarse aggregate; 50 to 80 parts of fine aggregate; 20-30 parts of a fiber filler; 10 to 20 parts of modified hollow microspheres; 400 to 600 parts of fly ash; 100 to 200 parts of water; the preparation method of the modified hollow microbeads comprises the following steps: adding acidic silica gel and methyltriethoxysilane into ethanol to obtain a mixed solution, adding alkali to adjust the pH value of the mixed solution to 5-7, then adding the hollow microbeads, sealing, controlling the temperature to 0-80 DEG C, aging for 24-72 hours, and drying to obtain the modified hollow microbeads. The thermal insulation concrete block provided by the invention has low heat conductivity coefficient and good thermal insulation performance.
本申请涉及混凝土砌块领域，具体公开了一种保温混凝土砌块及其制备方法。保温混凝土砌块包括如下重量份数的组分：水泥100‑200份；粗集料40‑70份；细集料50‑80份；纤维填料20‑30份；改性中空微珠10‑20份；粉煤灰400‑600份；水100‑200份；改性中空微珠的制备方法为：将酸性硅凝胶与甲基三乙氧基硅烷加入乙醇中得到混合液，加碱调节混合液的pH值为5‑7，然后加入中空微珠，密封后，控制温度为0‑80℃，陈化24‑72h，后干燥，即得改性中空微珠。本申请的保温混凝土砌块具有较低的导热系数，保温性能良好。
