The invention relates to thermal insulation concrete which comprises the following raw materials in percentage by weight: 5-30% of thermal insulation material particles and 70-95% of concrete, whereinthe thermal insulation material particles are any one or a mixture of two or more of expanded perlite, vitrified micro bubbles, extruded polyphenyl board crushed particles, polyurethane foam crushedparticles and aerogel powder; the concrete is concrete with national standard strength, any one of C7.5, C10, C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75 and C80 is prepared according to GB50010-2010 Concrete Structural Design Specifications, and the concrete can also be prepared according to the required strength; and in addition, a reinforcing agent can be added into the concrete to enhance the strength of the concrete. On the basis of good heat preservation performance, the heat preservation concrete has good mechanical performance, high strength, low cost, simple preparation process and good comprehensive performance, the heat conductivity coefficient is lower than that of concrete in the prior art, and the 28-day compressive strength can meet the technical requirements of construction.
本发明涉及一种保温混凝土，原料包括保温材料颗粒5％～30％，混凝土70％～95％；其中保温材料颗粒为膨胀珍珠岩、玻化微珠、挤塑聚苯板打碎后颗粒、聚氨酯泡沫碎后颗粒、气凝胶粉中任一种或两种及以上的混合物；混凝土为国家标准强度的混凝土，根据GB50010‑2010《混凝土结构设计规范》配制C7.5、C10、C15、C20、C25、C30、C35、C40、C45、C50、C55、C60、C65、C70、C75、C80中任一种混凝土，也可以为自己根据需要强度配制的混凝土；另外可在混凝土中添加增强剂来增加混凝土的强度。本发明的保温混凝土在保温性能良好的基础上，具有较好的机械性能、强度高、成本低、制备工艺简单，综合性能好，其中导热系数低于现有技术中混凝土的导热系数，28天抗压强度能满足施工技术要求。
