Fiberglass enhanced glass bead ceramsite foam concrete and preparation method and building block thereof

Abstract

The invention relates to the technical field of concrete, and in particular to fiberglass enhanced glass bead ceramsite foam concrete and a preparation method and a building block thereof. The fiberglass enhanced glass bead ceramsite foam concrete comprises the following raw materials in parts by weight: cement, coal ash, glass beads, swelling ceramsite, fiberglass, water, hydrogen peroxide, water reducing agent, and manganese dioxide. Compared with ceramsite foam concrete prepared by a physical foaming method in the prior art, a tensile property and compressive strength of a building block prepared by using a raw material of the fiberglass enhanced glass bead ceramsite foam concrete are greatly improved, and the building block is not easily cracked or broken during cutting, so that the building block prepared by using the raw material of the fiberglass enhanced glass bead ceramsite foam concrete is good in tensile performance, high in compressive strength, low in shrinkage, not easily cracked, and good in water absorption and tenacity. .

Description

technical field [0001] The invention relates to the technical field of concrete, and relates to a glass fiber-reinforced vitrified microbead ceramsite foam concrete, a preparation method thereof and a building block. Background technique [0002] Ceramsite concrete has attracted people's attention due to its advantages such as low bulk density and good thermal insulation effect, and has been promoted and used to a certain extent. However, ceramsite concrete has problems such as poor workability and difficulty in forming. Adding a proper amount of foam to the ceramsite concrete can greatly improve the workability of the ceramsite concrete and improve the pore structure of the concrete. [0003] The high porosity of ceramsite and foamed cement slurry in the ceramsite concrete block greatly reduces its own weight, and at the same time improves the thermal insulation performance of the block. The finished ceramsite concrete blocks have various sizes and specifications, whi...
