Description
Technical field
The invention belongs to technical field of civil engineering, is a kind of be used to the solidify green of the soil body, the environment-friendly type carbonization curing and device thereof of low-carbon (LC).
Background technology
Curing is the common method of reinforcing, improve soil mass property, it is in all sorts of ways curing compound is stirred, mixes with the soil body, improve physics, the mechanical property (water content, permeability, intensity, modulus etc.) of the soil body by the solidification (as the hydration of cement) of curing compound, thereby satisfy the civil engineering needs.At present, Chang Gui soil body curing compound is mainly cement and quicklime.Quicklime (GaO) is early stage main soil body curing compound, and quicklime can generate calcium hydroxide (Ga (OH) with the quick generation hydration reaction that water in soil divides
2), this reaction can reduce the water content in the soil body, and improve the character of the soil body, the calcium hydroxide of Sheng Chenging has gelatification simultaneously, thereby improve the intensity of solidified earth, but because the intensity of calcium hydroxide itself lower (cement relatively), the solidified earth intensity that it forms is not high, and is bad to the effect of Soft Ground.So the curing compound that (mainly being the agitation pile engineering) uses in the engineering is cement now, because the intensity of cement-soil is higher relatively, stable in properties.But cement needs high-temperature calcination in manufacturing process, calcining heat is about 1450 degree, simultaneously in cement production process, need to discharge a large amount of carbon dioxide, studies show that produce 1 ton of cement need be to 0.85 ton of carbon dioxide of airborne release, the carbon dioxide of cement industry discharging accounts for about 10% of anthropogenic discharge's carbon dioxide in the world.China bearing very heavy carbon dioxide discharge-reduction responsibility, and the civil construction field is one of main key areas of CO2 emission as the signatories to a treaty of Kyodo Protocol.For requirement on environmental protection; adopt the carbon dioxide capture technology in the industry of some high carbon dioxide dischargings; promptly utilize the carbon dioxide collection of corresponding techniques means with partial discharge, carbon dioxide how to handle these collections is an emphasis problem of current environment engineering research.Main method is with MAFIC ROCKS IN DEEP CRUST such as injection oil wells behind its boil down to liquid at present, seals then.But the long-time stability of this method also not through check, have potential leakage danger, and cost are very high.
The present invention is primarily aimed at the problems referred to above, the low-carbon (LC) that research and development can place of cement, the new soil carbonization curing and the device thereof of environmental protection.Novel soil body curing need satisfy three major requirements: (1) can satisfy actual engineering property needs, mainly is to want to reach the effect close or more excellent with cement on solidification intensity; (2) can satisfy low-carbon (LC), environmental requirement, the energy consumption and the CO2 emission of new method are lower than cement; (3) can satisfy the engineering economy needs, its cost can not be crossed and be higher than cement.Based on above consideration, the inventor has researched and developed the soil carbonization curing and the device thereof of a kind of green, low-carbon (LC) by a large amount of tests.
The curing compound main component that this method is used is activated magnesia (Reactive MgO), the calcining heat of activated magnesia manufacturing process is about 750 degree, far below cement (1450 degree), so be magnesia unslacked or light burnt powder again, magnesia that generates under this temperature and water reaction are very fast, and aquation generates magnesium hydroxide (Mg (OH)
2), so be called activated magnesia, its price equals or a little higher than cement.Too high when calcining heat, behind 1500 degree, the magnesia of generation loses activity, and is called dead roasting magnesia or crosses burned magnesium oxide.The intensity that activated magnesia solidifies the soil body is lower, the intensity of cement solidification soil under the same terms.But, the inventor finds that by a large amount of tests the activated magnesia solidified earth is easy to and carbon dioxide reaction (carbonization), particularly under the carbon dioxide environment of high solubility, high pressure, its carbonation process can be finished in several hours even dozens of minutes, generates the carbonate compound of magnesium.Inventor's experimental study result also shows, the activated magnesia solidified earth can improve greatly through intensity after the carbonization, near in addition surpass the intensity of cement-soil under the same terms.Carbonation reaction can consume a large amount of carbon dioxide, can absorb the carbon dioxide of 1.1 times of activated magnesia weight in theory during carbonization, thereby produce significant environmental effect, in the very short time, finish simultaneously the growth of solidified earth intensity, this characteristic to speedily carry out rescue work, special engineering such as the disaster relief has very important significance.Aquation similar with activated magnesia and carburizing reagent can take place in quicklime, can produce significant environmental effect equally, but the inventor finds that by test the intensity after the carbonization of quicklime solidified earth improves very limited, far do not reach the degree of cement solidification soil, but the price of quicklime is far below activated magnesia, its hydration process can reduce the water content of the soil body fast, increases the short-term permeability of the soil body, and this carbonization for solidified earth is extremely important.So, quicklime can be mixed use with activated magnesia, quicklime and activated magnesia play the water content of the quick reduction soil body jointly, increase the infiltrative effect of short-term of the soil body, for carburizing reagent creates conditions, and jointly by the environmental effect of carburizing reagent realization absorbing carbon dioxide, growth plays a major role and activated magnesia process hydration and carbonization are to soil strength.
In sum, although can discharge a large amount of carbon dioxide with cement is the same in activated magnesia and the quicklime manufacturing process, but can a large amount of absorbing carbon dioxides in the solidified earth carbonation process, so from production, the use overall process of product, its CO2 emissions be far below cement.
Summary of the invention
Technical problem: the purpose of this invention is to provide a kind of low-carbon (LC) of civil engineering, the soil carbonization curing and device thereof of environment-friendly type of being used for, the present invention can be under situation about reaching with near solidification intensity of the existing cement solidification soil phase and construction costs, reduce energy consumption and CO2 emission in the corresponding civil engineering, produce significant environmental effect, in the very short time, finish simultaneously the gain in strength of solidified earth, satisfy speedily carry out rescue work, in the special engineering such as the disaster relief to the requirement of engineering time.
