Abstract

The invention discloses heat-insulation type concrete for civil construction and belongs to the technical field of concrete. The heat-insulation type concrete is prepared from the following raw materials in parts by weight: 90 to 100 parts of cement, 20 to 25 parts of fly ash, 40 to 50 parts of fine sand, 10 to 20 parts of ceramsite, 5 to 8 parts of cast stone powder, 6 to 9 parts of zeolite powder, 60 to 70 parts of water, 1 to 2 parts of fiber, 0.5 to 1 part of a waterproof agent, 1 to 3 parts of a de-foaming agent, 0.2 to 0.8 part of a suspension agent and 0.1 to 0.2 part of an activating agent. The invention further discloses a preparation method of the heat-insulation type concrete for the civil construction. The heat-insulation type concrete for the civil construction is simple to prepare and has relatively excellent waterproof, fireproof and heat-insulation capabilities.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a thermal insulation concrete for civil engineering and a preparation method thereof. Background technique [0002] Thermal insulation concrete, also known as aerated concrete, foam concrete, and foamed concrete, belongs to the category of thermal insulation materials. It covers the surface of thermal equipment and pipelines, which can prevent or reduce heat exchange with the outside world and reduce heat dissipation. Special concrete with certain physical and mechanical properties. [0003] Insulation concrete is made of foam by mechanical means, and then the foam is mixed into the mixture composed of siliceous materials, calcium materials, etc. Specifications, cured lightweight concrete with a large number of closed pores. Foam concrete has a large number of closed small pores, which has good thermal insulation performance and can be used as wall thermal insulation material....
