AI Technical Summary

Technical Problem

Existing concrete modular prefabricated houses have shortcomings in ensuring the quality and performance of concrete, resulting in limited safety and service life of the building.

Method used

The new formula of concrete is used, including cement, fume, stone powder, quartz sand, water reducing agent, steel fiber and anti-cracking agent, and the amount of anti-cracking agent is 4% of the total weight of cement and fume. In addition, integrated radar wave non-destructive testing equipment is used to detect defects in concrete.

Benefits of technology

By incorporating anti-cracking agents, the tensile strength of concrete is significantly improved and the quality and safety of the house are improved. Radar wave non-destructive testing equipment can promptly detect concrete defects, avoid its application in the house, and reduce safety hazards.

Abstract

The invention discloses a concrete modular assembly type house which comprises a house body, the house body adopts concrete with a novel formula, and the concrete is prepared from the following raw materials in parts by weight: 730-750 parts of cement, 210-240 parts of silica fume, 220-240 parts of stone powder, 1000-1050 parts of quartz sand, 30-35 parts of a water reducing agent, 200-210 parts of steel fibers, 180-200 parts of water and a mixing amount of an anti-cracking agent. The mixing amount of the anti-cracking agent is 4% of the total weight of the cement and the silica fume. According to the invention, a certain amount of the anti-cracking agent is innovatively doped into the concrete, so that the tensile strength of the concrete is improved, and a concrete modular fabricated house using the concrete is higher in quality and better in safety.
