Embodiment 1

[0024] Embodiment 1: a kind of preparation method that utilizes granite slag powder as the foam light soil of main raw material, comprises the steps:

[0025] (1) Weigh raw materials according to the following components: 50 parts by mass of granite slag powder, 15 parts by mass of pozzolan cement, 12 parts by mass of slag, 1 part by mass of water reducer, and 22 parts by mass of foam;

[0026] (2) Classify the granite slag powder with a 2mm square hole sieve, sieve out the thicker part on the sieve, and sell it as construction sand, and dry the part under the sieve to a moisture content of 0.5%; The gravel powder is classified with a 1mm square hole sieve, the part above the sieve is sold as fine aggregate, and the part under the sieve is ground in a mill until the specific surface area is 2500cm 2 / g.

[0027] (3) Mix and grind the stone powder ground in step 1 with the dried water-quenched blast furnace slag until the specific surface area is 3000cm 2 / g, where the moistu...

Embodiment 2

[0031] Embodiment 2: The component content of the foam light soil is as follows: 52 parts by mass of granite slag powder, 16 parts by mass of pozzolan cement, 10 parts by mass of slag, 1 part by mass of water reducing agent, and 21 parts by mass of foam; The preparation process is the same as in Example 1.

Embodiment 3

[0032] Embodiment 3: The component content of foam lightweight soil is as follows: 5:4 mass parts of granite slag powder, 16.5 mass parts of pozzolan cement, 9 mass parts of slag, 1.5 mass parts of water reducer, 19 mass parts of Foam; The preparation process is the same as in Example 1.

Abstract

The invention discloses foam light soil with granite ballast powder as a main material and a preparation method of the foam light soil. The foam light soil is prepared from, by mass, 45-60 parts of the granite ballast powder, 11-20 parts of pozzolana cement, 7-15 parts of slag, 0.8-1.9 parts of a water reducing agent and 14-25 parts of foam. Cement is replaced by the granite ballast powder to serve as the main material for foam light soil production, and the foam light soil prepared by taking the granite ballast powder as the main material is superior to existing foam light soil mainly prepared from cement in the mechanical property of uniaxial compressive strength, so that production cost is reduced, product performances are improved, and a high market value is achieved. Further, by adoption of the granite ballast powder in specific particle size, compressive strength of the foam light soil is greatly improved, and the uniaxial compressive strength is improved by 50% or above.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a foam light soil with granite rock slag powder as the main raw material and a preparation method thereof. Background technique [0002] Foam light soil, which is defined as fully foaming the foaming agent mechanically through the foaming system of the foaming machine, and uniformly mixing the foam with the cement slurry, and then passing through the pumping system of the foaming machine for cast-in-place construction or mold Forming, a new type of lightweight thermal insulation material containing a large number of closed pores formed by natural curing. It belongs to the bubble-like thermal insulation material. The outstanding feature is the formation of closed foam pores inside the concrete. It has light weight, high compressive strength, and integrity. It can be used for abutment abutment backfill, road widening, bridge span reduction, steep embankment, landslide subgrade, so...
