Composite self-insulation concrete block and production method thereof

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of concrete, and relates to a composite self-insulating concrete block and a production method thereof. Background technique [0002] In recent years, with the continuous development of my country's social economy and the continuous acceleration of urbanization, the market demand for buildings has become increasingly strong, and the construction industry has developed rapidly, but this has also brought huge resources, energy and environmental carrying capacity. pressures and challenges. In the general trend of the development of the construction industry, people have gradually realized that building energy conservation is an important part of it, and it is also a key link in implementing the national sustainable development strategy. [0003] In the past 20 years, building energy conservation has flourished in the world and has become a hot issue of common concern. Many countries have formulated regulations ...
