Description

Technical field [0001] The manufacturing method of the inorganic thermal insulation load-bearing building block of the present invention belongs to the technical field of thermal insulation building blocks. Background technique [0002] In recent years, concrete porous blocks have been used in construction engineering as a new type of load-bearing wall material. The porous concrete block is made of concrete as the raw material through molding and curing. The manufacturing process is simple, the curing is convenient, and no sintering is necessary. However, the concrete porous block also has the following defects: [0003] First, it is not suitable for underground parts of buildings, as these parts have higher requirements for local compression capacity; [0004] Second, the hole size is small and the number is large. Special equipment is required for molding, dry concrete is required, and material requirements are high; [0005] Third, the thermal conductivity of the concrete porous ...

AI Technical Summary

Problems solved by technology

[0003] First, it is not suitable for the underground part of the building, and the local pressure capacity of these parts is relatively high;

[0004] Second, the size of the holes is small and the number is large, special equipment is required for forming, dry hard concrete is required, and the material requirements are high;

[0005] Third, the thermal conductivity of concrete porous blocks is 1.51W / (m·K). Although its large porosity is conducive to heat preservation, it has concrete ribs of a certain width and concrete structural columns or cores at joints and corners. There are weak points in the columns, which are easy to form thermal bridges and affect the thermal insulation performance

However, the thermal insulation performance of concrete itself is poor, resulting in poor thermal insulation performance of concrete solid blocks, and the bulk density is large, which increases the building load and foundation cost after use. Some places have restricted the use of concrete solid blocks
