Composite self-insulation concrete block and production method thereof
The invention discloses a composite self-insulation concrete block. The composite self-insulation concrete block is composed of a concrete hollow block and an inner core material in a cavity of the concrete hollow block, wherein the inner core material is a low density foam concrete, the raw materials comprise a cement mortar and foamed foams with a volume ratio being 1:4-8, and the composite self-insulation concrete block is prepared by mixing the foamed foams and the cement mortar, casting a mixture in the cavity in the concrete hollow block, and performing natural maintenance. A production method comprises the following steps: 1) preparing the foams and preparing the cement mortar; 2) preparing a foam mixing slurry; and 3) casting and maintaining the material. The composite self-insulation concrete block can reach the requirements of heat transfer coefficients prescribed by a national standard and can satisfy the heat insulation requirements in hot summer and cold winter areas, the heat insulation performance of the composite self-insulation concrete block is stronger than that of the concrete hollow block, the heat transfer coefficients account for 80% of that of the hollow building block unfilled with the foam concrete, and thermal resistance of the composite self-insulation concrete block can reach as high as 1.25 times of that of the hollow building block.
