Description
Technical field
The present invention relates generally to a kind of antifreezing agent that is used to improve concrete frost resistance, and particularly a kind of is the concrete antifreezing agent of main component with the waste rubber powder, belongs to building material technical field.
Background technology
Waste old is mainly derived from rubber items such as damaged tire, scrap rubber footwear, scrap rubber pipe and adhesive tape, and next derives from scrap stock and the waste product that produces in the rubber production process, belongs to using industrial solid waste.Waste rubber belongs to thermoset copolymer material, is difficult to degraded under the natural condition.If outdoor storage, not only land occupation, worsen physical environment, destroy plant-growth, and very easily grow mosquito through after exposing to the sun and rain, spread disease, jeopardize ecotope.At present, about 2,000 ten thousand tons of the annual production of whole world waste old, the annual production of China's waste old are estimated to have reached 1,500,000 tons, wherein doughnut whole world year learies has more than 1,000,000,000, according to statistics, China's junked tire in 2002 reaches 8,000 ten thousand, reaches 1.12 hundred million in 2005.Along with the develop rapidly of automotive industry, the generation of China's junked tire is also with double-digit speed increment in every year, and the annual production that expects waste old in 2010 will reach 200,000,000.So a large amount of waste rubbers brings very big environmental stress, thereby the processing of junked tire is extremely urgent.Because reclaimed rubber is easy to generate secondary pollution in process of production, producing rubber powder has become the main path that waste old is recycled.In addition, China's rubber resource is in short supply relatively, almost rubber year consumption 45% need import.Therefore, carry out the comprehensive utilization of waste Crumb rubber, to the protection environment, economizing on resources has important theory and realistic meaning.
Since the twenties in 19th century, portland cement came out, concrete material and utilisation technology thereof were constantly developed.Concrete has now become consumption maximum in the modern civil engineering, material of construction that purposes is the widest.If can correctly design concrete according to environment for use, to construct on request and maintenance simultaneously, concrete will be a kind of very competent structured material, can reach a century even more of a specified duration its work-ing life.Yet the freeze-thaw cycle effect is world's cold district, and particularly the one of the main reasons of severe cold area concrete destruction occurs in the buildings that dam, road, pond, power station cooling tower etc. contact with water mostly.Past has all occurred considerable concrete structure both at home and abroad because of being subjected to freeze thawing Circulation destructive example too early because concrete freeze-thaw damage problem is paid attention to inadequately.Along with the continuous development of concrete technology, people mix air entrapment agent and can effectively improve concrete frost resistance by discovering in concrete.At present, the air entrapment agent type that is used to improve concrete frost resistance mainly contains bathvillite salt, rosin early and colophonium pyrolytic polymer, saponin class and alkylaryl sulphonate class.Though above-mentioned bleed type antifreezing agent can effectively improve concrete frost resistance, loss, promptly usually said air content damage problem all can appear in micro-bubble that they are introduced inevitably in the process that stirs, transports and build.Air content loss problem makes the concrete true air content in sclerosis back be difficult to design or control, and concrete true air content is too high, can reduce concrete intensity; Air content is low excessively, is difficult to reach the frost resistance of expection.
In sum, waste rubber has brought the serious environmental pressure and the wasting of resources to us on the one hand, and on the other hand, the cement concrete of north cold area is faced with serious freeze-thaw damage problem.Therefore, if can solve concrete freeze-thaw damage problem, not only protect environment, economize on resources, and can improve the concrete frost resistance of China's cold district, have important environmental benefit and economic benefit with rubber powder.
Summary of the invention
The technical problem to be solved in the present invention is problem of environmental pollution, concrete freeze-thaw damage problem and interpolation bleed type air content that antifreezing agent the produces loss problem in concrete that waste rubber causes.
According to available coagulation soil freeze injury theory, be in when below freezing at concrete, at first be to begin to freeze near the free water content in the hole on surface, about 9% volumetric expansion takes place.Produced frost heave stress at inside concrete, thereby moved to inside concrete after making the moisture pressurized that does not freeze.Just produced hydrostaticpressure when migration is tied, hydrostaticpressure repeatedly makes the microfracture of inside concrete vulnerable area expand gradually, be communicated with until destruction.After mixing air entrapment agent in the concrete, owing to introduce a large amount of micro bubbles, be evenly distributed on inside concrete, just can hold the migration of free water, thereby relaxed hydrostaticpressure widely, this just can improve concrete significantly and bear multigelation round-robin ability.The applicant is by discovering, rubber is macromolecular elastomer, rubber powder is mixed in the concrete can relax hydrostaticpressure equally, improves concrete frost resistance, and there is not the air content loss problem of bleed type antifreezing agent in rubber powder as antifreezing agent.
According to concrete destruction mechanism of frost-thawing as can be known, water is one of prerequisite of concrete generation freeze-thaw damage.Therefore, improve concrete impermeability, stoping moisture to enter inside concrete also is one of important measures that improve concrete frost resistance.There are some researches show, concrete is before bearing load or external stress, because the recrystallize and the slurry of chemical shrinkage, dry shrinkage, carbonization, hydrated product and the effects such as difference between the thermal expansivity of gathering materials, the tiny crack or the hole of a large amount of stochastic distribution in the inside concrete disperse, and these tiny cracks or hole provide passage for moisture infiltrates inside concrete.Therefore, reduce concrete contraction, the quantity that reduces the inside concrete tiny crack is also very crucial to improving concrete frost resistance.The effective measure that reduce concrete shrinkage at present are to mix swelling agent in concrete.The applicant is through research, following discovery is arranged: composite by a certain percentage the effect of anhydrite and alum stone flour with compensating concrete early-age shrinkage, but its expansion behavior mainly is created in before the 28d, and is not obvious to the compensating action that the concrete later stage (28d is after the length of time) shrinks.And MgO also can be used as concrete swelling agent, and it mainly after being embodied in 28d, has complementarity with the expansion of anhydrite and alum stone flour to the compensating action of concrete shrinkage.
Based on above-mentioned research and discovery, for solving the problem that aforementioned prior art exists, it is main raw material(s) that the present invention adopts rubber powder, carry out composite with anhydrite, alum stone flour, MgO and water reducer, make a kind of environment-protecting and energy-saving concrete antifreeze agent, both solve the problem of environmental pollution of waste rubber, solved concrete freeze-thaw damage problem again, also can avoid the air content loss problem of bleed type antifreezing agent simultaneously.
