Description

A kind of discarded granite stone powder air bubble mix light-textured soil of high additive
Technical field
The invention belongs to the field of building materials, are related to the recycling of waste material of stone, specially useless using processing of stone The method for expecting to prepare foams mix light soil.
Background technique
Air bubble mix light-textured soil is that prefabricated foam group is added in a kind of cementitious material slurry good to mixing, acquisition Porous light engineering filling material.Its with light weight, compression strength is high, intensity is adjustable, good integrity, high fluidity, resistance to Long property is good, condensation independence, insulation and the features such as good application property, can be used for Abutment Back backfill, road widening project, Bridge cross-cut, Steep Slope Embankment, landslide roadbed, soft soil roadbed off-loading, underground structure off-loading, the slip casting of tunnel cavity, old bridge reinforcement With the engineerings such as frozen earth roadbed insulation.
It is cementitious material that the existence of Foam lightweight soil at present uses cement more, and production cost with higher is huge latent Thermal technology's energy consumption.On the other hand, we largely use stone material in construction projects, and stone material is processed in saw blade, cutting, grinding etc. The leftover pieces and powder generated in engineering.The stacking of these stone material fine powders be easy to cause soil depletion, underground water pollution and powder Dustiness dye, causes environment seriously to break ring.So used in air-entrained concrete building block, it can the effectively save cost of raw material And natural resources, alleviate the pollution to environment.
Summary of the invention
The invention discloses a kind of high additives to discard granite building material mountain flour air bubble mix light-textured soil and preparation method thereof.It should This is discarded for the discarded granite stone powder that method can largely mix stone material cutting in air bubble mix light-textured soil, generate in bruting process Granite stone powder, is not only able to reduce material production cost, moreover it is possible to carry out recycling treatment to waste stone powder, alleviate to environment Pollution.
To reach above-mentioned technical purpose, the air bubble mix light-textured soil in the present invention includes: discarded granite stone powder 21~25 Part, 9~10 parts of ordinary portland cement, 3~4 parts of silicon ash, 1~2 part of composite exciting agent, Modified Organosilicon Waterproofing Agent 0.5~1.0 Part, 10~20 parts of water, 1~5 part of foam.High additive prepared by the present invention discard granite building material mountain flour air bubble mix light-textured soil its Density is 500~1200kg/m3, 1.0~10MPa of compression strength, and it is at low cost, there is good waterproof performance and mobility Can, it is suitable for various engineering filling materials.
In above technical scheme: the discarded granite stone powder, it is characterised in that granite building material waste material drying wind It is weighed after choosing with lime 8:2 in mass ratio, fineness is controlled in 350~400m of specific surface area2/kg;
The ordinary portland cement is P.O.42.5 or P.O.42.5R cement;
The silicon ash is byproduct of the ferroalloy in smelting duriron and industrial silicon (metallic silicon), specific surface area 20000- 30000m2/kg;
The composite exciting agent, it is characterised in that including gypsum, soda ash, triethanolamine, free calcium oxide clinker, sodium water Glass, mass percent 15%:10%:15%:30%:30%;
The Modified Organosilicon Waterproofing Agent is to extend to (polymeric material by segment on the basis of methane-siliconic acid alcohol Amount)/(monomer mass)=0.1~0.6, acrylate segment is then introduced on the basis of long-chain-segment again, and waterproof is reached with this Durable purpose.
The high additive discards the preparation method of granite building material mountain flour air bubble mix light-textured soil, comprising the following steps:
1) discarded granite stone powder is weighed by weight, ordinary portland cement, silicon ash, composite exciting agent, modification is organic Silicon waterproofing agent, water, foam;
2) granite stone powder, ordinary portland cement, silicon ash, composite exciting agent, modified organic silicon will be discarded in step 1) After waterproofing agent and water are mixed evenly, foam is added thereto, the density of adjustment gained mixed slurry is 500~1200kg/ m3To get the full slag Foam lightweight soil.
Technical principle of the invention are as follows:
1) present invention is effectively utilized processing of stone waste material, after being mixed with drying with sorting and with lime, is The predominantly granite stone powder waste material of SiO2 provides potential hydration and hardening and needs CaO, and it is uniform to improve stone powder particles Property, potential activity improves, has recycled solid waste, saved resource, is conducive to local environment and protects.
2) since waste stone powder does not pass through high-temperature burning process, activity is relatively low, therefore uses gypsum, soda ash, three Ethanol amine, free calcium oxide clinker, sodium silicate carry out review excitation, have certain chemical bonding potential energy, while these water Change condensation of the product as nuclei of crystallization acceleration of hydration gel, promotes the combination such as Ca and Si and form intensity.
3) it joined modified organic silicon composite water-proof agent, reduce the water absorption rate of air bubble mix light-textured soil, be more suitable for it For in the reclamation work of rich groundwater.
4) since the early hydration speed of mountain flour is slow, and Foam lightweight soil needs to have certain early strength, to avoid It collapses the risk of mould, and improves production efficiency, the silicon ash of mass ratio 3% is added in the present invention, improves early strength.
Compared with prior art, the beneficial effect comprise that
1) using granite building material processing waste material processing reprocessing, the Utilizing question of local waste material of stone is efficiently solved, Natural resources has been saved, ecological environment is protected;
2) first compare with common high additive waste residue air bubble mix light-textured soil, the present invention has higher early strength, and has Preferable waterproof performance.
