Abstract

The invention relates to full-lightweight ceramsite concrete and a preparation method thereof. The full-lightweight ceramsite concrete is prepared from, by weight, 278-339 parts of cement, 318-344 parts of ceramsite, 334-382 parts of pottery sand, 50-55 parts of coal ash, 35-42 parts of silica fume, 0.001-3 parts of triisopropanolamine, 0.5-3 parts of a water reducing agent and 0.001-3 parts of athickening agent. The method includes steps: subjecting ceramsite and pottery sand to surface pretreatment through alkyl alkoxy silane, prewetting ceramsite and pottery sand to achieve a saturated surface dry state, then sequentially feeding lightweight aggregates, cement, silica fume and coal ash into a forced mixer, and well mixing to obtain the full-lightweight ceramsite concrete. The full-lightweight ceramsite concrete prepared according to the method has advantages of light weight, high peaceability and effectiveness in inhibition of ceramsite floating and has a promising application prospect in the field of energy-saving construction engineering.

Description

technical field

[0001] The invention relates to the field of building materials, in particular to an all-light ceramsite concrete and a preparation method thereof. Background technique

[0002] Light aggregate concrete is a kind of concrete prepared with light aggregate and cement, with an apparent density not greater than 1950Kg / m3. Among them, the most widely used ceramsite concrete is the concrete prepared by ceramsite, light sand (or ordinary sand), cement and water. Compared with ordinary concrete, it can reduce its own weight by 20% to 25% while maintaining high strength, and has high durability. It also has thermal insulation, heat insulation, fire resistance, corrosion resistance, environmental protection, and good earthquake resistance. advantage. But it still has some shortcomings, such as the self-weight is still relatively large, and the aggregate floats seriously, which leads to poor process effect. Generally, in order to further reduce the bulk density of li...
