Description
Technical field
The invention belongs to building material field, and in particular to a kind of early strength micro expansion type soil-solidified-agent and preparation method.
Background technology
Soil-solidified-agent is a kind of engineering material of the environment-friendly energy-saving by various organic and inorganic materials synthesis.Construction
During curing agent and soil it is well mixed, diminish in the impressed pressure intergranular spacing of soil under action earth, and sent out with curing agent
Raw a series of physical chemical reaction, to reach filler particles between space, improve soil particle surface characteristic and generation gelatinous mass
Condense the effect of soil.Soil-solidified-agent have raw material sources extensively, can gather materials on the spot, construction technology is simple, engineering is made
The low various advantages of valency, so all having ten in terms of technology, energy economy ＆ environment protection etc. using the solid soil of soil-solidified-agent stabilization
Divide important meaning.The soil-solidified-agent species used in current engineering is more, wherein cement base soil-solidified-agent and lime base
Soil-solidified-agent application is more universal.
Cement base soil-solidified-agent mainly generates the hydrated products such as hydrated calcium silicate by clinker aquation, with soil
There are various physical-chemical reactions in grain, and the aggregates such as sandstone is cementing integral, be remarkably improved solidification soil strength.Lime base
Soil-solidified-agent is after quick lime mixes with soil, generation Ca to be acted on by water swelling, heat release and hydration reaction etc.
(OH)2, then gel phase is generated with the effect of other mineral admixtures, and then improve soil strength.But in long-term soil solidification
In engineering practice, people gradually, it is realized that carry out that the general shrinkage of soil solidification is larger using cement, cracking risk is higher, and
And it is poor to the adaptability of soil property.By contrast, the effect using lime material solidification soil is preferable.And lime in itself early stage
Low intensity, it is impervious poor, limit the extensive use of lime base soil-solidified-agent.Therefore, develop that a kind of early strength is high, water is steady
Property soil-solidified-agent good, with microdilatancy characteristic is then particularly important.
Rice husk be rice processing Main By product, the annual rice husk of China yield more than 40,000,000 t.If be not subject to
Rationally utilize, can not only cause the waste of resource, can also bring immense pressure to the environment on periphery.Rice hull ash is used as combusting rice hull
Product afterwards, its specific surface area is big, and main component is SiO2, with pozzolanic activity very high, can improve the early stage of lime
The performance such as intensity and impermeability.Therefore in lime base soil-solidified-agent, rice hull ash can by force promote to be carried with impervious as a kind of morning
Rise agent incorporation to use, this not only realizes the reusable edible of rice hull ash, turns waste into wealth, and to preserving the ecological environment, implements
Sustainable development idea has far-reaching practical significance.
The content of the invention
Present invention aim at a kind of soil-solidified-agent of offer and preparation method.
It is as follows using technical scheme to reach above-mentioned purpose：
A kind of early strength micro expansion type soil-solidified-agent, its composition is counted as follows by weight：
The lime raw material is any one of calcium hydroxide, quick lime, carbide slag or mixes；The morning promotes by force and anti-
It is rice hull ash or white carbon or its combination to ooze elevator；It is flyash or slag powders or its group that the activity promotes material
Close；The micro-expanding agent is any one of the natural gypsum, anhydrite, ardealite, fluorgypsum or mixes.
By such scheme, the composition of optimization counts as follows by weight：
By such scheme, the composition of optimization counts as follows by weight：
By such scheme, the morning promotes by force and impervious elevator is rice hull ash.
By such scheme, it is flyash that the activity promotes material.
By such scheme, the micro-expanding agent is ardealite.
The preparation method of above-mentioned early strength micro expansion type soil-solidified-agent, comprises the following steps：
Lime raw material, early strong promotion and impervious elevator, activity are promoted into material, micro-expanding agent combined grinding, is obtained
Soil-solidified-agent.
By such scheme, 350cm is more than using ball mill combined grinding to specific surface area2/g；Or 0.08mm is tailed over and is less than
10%.
The Main Function of lime raw material is that the intensity for ensureing soil-solidified-agent of the present invention is formed, it is ensured that soil solidification body
Alkaline environment in system.
The Main Function of early strong promotion and impervious elevator is quick with alkali using nano active silica therein
Reaction and micro-aggregate filling effect, promote the early strong anti-permeability performance for being formed, improving the soil body of the solidification soil body.
The Main Function that activity promotes material is that sustainable reaction is produced in alkaline environment using active material therein
Raw hydrated product, on the one hand gradually promotes the intensity of the solidification soil body, it is ensured that later strength, on the other hand improves soil body compactness,
Improve impervious.
The Main Function of micro-expanding agent is to compensate the soil body to shrink, and suppresses cracking.
Relative to prior art, the device have the advantages that being：
By the effect of early strong promotion and impervious elevator etc., the lime firming agent for soil solidification soil body is significantly improved
Early strength, shortens cure cycle, improves the water stabilizing of the soil body.
By the effect of activity excitant, the sustainable growth of solidification soil strength is realized.
By the effect of micro-expanding agent, the micro-expansibility energy of the solidification soil body is realized, suppress shrinkage cracking；Meanwhile, can be big
Amount is using solid waste such as carbide slag, flyash, slag, rice hull ash, ardealites, and economic and environmental benefit is notable.
