Vitrified microbead lightweight concrete and preparation method thereof
The invention belongs to the technical field of concrete production, and discloses vitrified microbead lightweight concrete and a preparation method thereof.The vitrified microbead lightweight concrete has the following indexes that the dry apparent density is 1000-1900 kg/m, and the compressive strength is 25-70 MPa; and the heat conductivity coefficient is 0.15-0.40 W/(m.K) when the average temperature is 25 +/-2 DEG C. The concrete disclosed by the invention has the characteristics of light weight, high strength, heat insulation and fire resistance, and the glass beads are adopted, so that the density of the concrete is reduced, the fire endurance of the concrete is improved, and the heat conductivity coefficient of the concrete with the same strength grade is reduced.
本发明属于混凝土生产技术领域，公开了一种玻化微珠轻质混凝土及其制备方法，其中玻化微珠轻质混凝土，具有如下指标：干表观密度为：1000～1900kg/m³、抗压强度为：25～70MPa；在平均温度为25±2℃时的导热系数为：0.15‑0.40W/(m·K)，本发明中的混凝土具有轻质、高强度、绝热耐火特性，采用玻化微珠降低了混凝土密度，提高了混凝土耐火极限，降低了同强度等级混凝土的导热系数。
