Embodiment 1

[0030] In this example, the various components and mass ratios of the regenerated lightweight aggregate thermal insulation concrete are: cement: fly ash: slag powder: admixture: foamed cement waste: water = 34:5:10:3:48: twenty four.

[0031] The preparation method is as follows:

[0032] 1) Put cement, admixture (that is, fly ash and slag powder in the above components), admixture and water into the mixer according to the above ratio and stir evenly;

[0033] 2) Put the regenerated light aggregate (that is, the foamed cement waste in the above components) into the mixer evenly according to the above ratio, and stir evenly with the mixed materials in the step 1) to obtain The regenerated light aggregate heat-preservation concrete of the present invention.

Embodiment 2

[0035] In this example, the various components and their mass ratios of the recycled lightweight aggregate thermal insulation concrete are:

[0036] Cement: fly ash: slag powder: admixture: foamed cement waste: cinder: water = 34:5:10:3:36:12:24.

[0037] The preparation method is as follows:

[0038] 1) Put cement, admixture (that is, fly ash and slag powder in the above components), admixture and water into the mixer according to the above ratio and stir evenly;

[0039] 2) Put the regenerated light aggregate (i.e. the foamed cement waste and coal cinder in the above components) into the mixer evenly according to the above ratio, and stir evenly with the materials in the step 1) to obtain the present Invention of the regenerated lightweight aggregate thermal insulation concrete.

Embodiment 3

[0041] In this example, the various components and their mass ratios of the regenerated lightweight aggregate thermal insulation concrete are: cement: fly ash: slag powder: admixture: foamed cement waste: vitrified microbeads: water = 34:5:10 :2.5:38:10.5:26.

[0042] The preparation method is as follows:

[0043] 1) Put cement, admixture (that is, fly ash and slag powder in the above components), admixture and water into the mixer according to the above ratio and stir evenly;

[0044] 2) The composite light aggregate composed of regenerated light aggregate (i.e. foamed cement waste in the above components) and commercially available light aggregate (i.e. vitrified microbeads in the above components) is also uniformly mixed according to the above ratio put into the mixer, and stir evenly together with the materials in the step 1) to obtain the regenerated light aggregate thermal insulation concrete of the present invention.

Abstract

The invention discloses regenerated light aggregate heat preservation concrete which consists of a component A and a component B, wherein the component A consists of the following materials in percentage by weight: 25-34 percent of cement, 10-15 percent of an admixture, 23-48 percent of regenerated light aggregates, 0-25 percent of commercially available light aggregates and 2-3 percent of an additive; the component B is water; the weight of the component B is 24-26 percent of the total weight of the component A. According to the regenerated light aggregate heat preservation concrete, industrial wastes are fully used, and the properties of all the aspects of the heat preservation concrete are improved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to thermal insulation concrete prepared by utilizing recycled light aggregates. Background technique [0002] With the improvement of people's requirements for living comfort, building energy consumption has increased sharply, and energy conservation and environmental protection have become an important part of building energy-saving design. Research and development of building materials that meet green thermal insulation and energy conservation are very important topics. Regulations on external wall thermal insulation systems of civil buildings and exterior wall decoration fire protection regulations restrict traditional organic thermal insulation materials, and recommend non-combustible materials or flame-retardant materials as thermal insulation layers. Inorganic thermal insulation concrete has the characteristics of safety, greenness, durability, and high ...
