High-strength light composite building material

Abstract

The invention relates to a high-strength light composite building material. The high-strength light composite building material is prepared from the following components in parts by weight: 15 to 19 parts of hydrophobic pearlite, 30 to 47 parts of barium stearate, 20 to 24 parts of graphite powder, 10 to 14 parts of cadmium stearate, 5 to 8 parts of calcium stearate, 3 to 8 parts of polyvinyl chloride, 15 to 19 parts of foaming material, 18 to 22 parts of limestone and 18 to 25 parts of diatomite. By adopting the high-strength light composite building material, the rupture strength and toughness of the composite building material can be enhanced effectively, the crack width is limited, and surface cracking of the composite building material is resisted; the high-strength light composite building material can be widely applied to composite building material structures in the fields of civil engineering, water conservation, municipal transportation, marine military industry and the like.

Description

technical field [0001] The invention belongs to the field of construction and relates to a high-strength and lightweight composite building material. Background technique [0002] The performance of building materials will gradually change after long-term exposure to external influences such as wind, sun, rain, wear, and corrosion. The rational formulation of building materials is very important. First of all, it should be safe and durable. The amount of building materials used is large. It affects the cost of the project. Usually, the cost of building materials accounts for more than half of the total cost of the project. Therefore, when considering the technical performance and structural strength requirements, it also leads to an increase in construction costs. There is a need for a low specific gravity, lightweight building material.
