Description
Technical field
The present invention relates to geo-polymer and regeneration aggregate, more particularly to geo-polymer and regeneration aggregate combine the method for preparing concrete, to realize the recycling of the comprehensive utilization of geo-polymer, regeneration aggregate.
Background technology
With the continuous increase of current Domestic Environment pressure, heat power station production flyash is on the increase, and the building trade of high speed development receives attention extensively to the demand of New Building Materials, the research to the geology polymer material with flyash as raw material.
About 6.5 hundred million square metres of the annual newly constructed house of China, every ten thousand square metres of about 500-600 tons of rubbish of discharge, nearly 40,000,000 tons of the building waste that annual only construction is produced and discharged.In addition, it is also what be can not be ignored that we should also be seen that Old building removes rubbish, every square metre of Old building removes about 0.5-0.7 tons of waste material, old room removes 10% calculating of the area by newly-built area, then house breaking rubbish is at 40,000,000 tons or so, the above two adds up to, about 80,000,000 tons of the annual yield of China's building waste.Secondly, the discharge of building waste also result in many social effects of pollution, have impact on the quality of life of the people.As can be seen here, the processing cost of the building waste of such flood tide well imagines, and the environmental problem for thus triggering is also apparent from (pollution such as to the occupancy, the destruction of landscape, dust ploughed to environment).Therefore, the regeneration of building waste oneself turn into the problem paid close attention to jointly of World Developed Countries construction and environmental administration, also thus triggered further investigation of the various countries to the regeneration of building waste.
Conventional cement in regenerated aggregate concrete is replaced using geo-polymer, geo-polymer recycled aggregate concrete is made, the advantage of geo-polymer can be made full use of, while also having recycled building waste, be conducive to environmental protection.
The content of the invention
One of technical problems to be solved by the invention are to provide the combination of a kind of geo-polymer and regeneration aggregate, prepare the formula of concrete, so that the cost of concrete product is greatly reduced, and can realize the recycling of building waste.
The technical scheme that solution technical problem of the invention is used is as follows：
First, using orthogonal test, self-igniting coal gangue volume, the influence of doping quantity of fly ash, three factors of slag and exciting agent Water glass content to geology polymer latex sand intensity are investigated.By the extreme difference to orthogonal experiments, variance analysis, optimized mix-proportion parameter, to obtain the optimum mix proportion of geo-polymer：Gangue：Flyash：Slag：Exciting agent waterglass=2：1：1：0.56.
Secondly, geo-polymer is made according to optimum mix proportion, regenerated coarse aggregate, sand, water is added, to be fabricated to geo-polymer recycled aggregate concrete.
Then, then to made geo-polymer recycled aggregate concrete carry out, the basic mechanical property test such as anti-folding, resistance to compression, tension, wearability.If the mechanical property for testing out reaches requirement of engineering standard, large-scale production is carried out according to this match ratio, be such as unsatisfactory for requiring, then readjust the match ratio of concrete, repeated and tested, the concrete of requirement of engineering mechanical property is met until drawing.And by concrete mix now, as the match ratio of large-scale production.
Specific embodiment
Treatment first is analyzed to gangue, flyash.By self-igniting coal gangue block by pulverizing and jevigating, powder of the particle diameter less than 0.16mm is become, spontaneous combustion gangue powder specific surface area is more than 300 ㎡/kg；Granularity to flyash carries out detection process so that its specific surface area is more than 300 ㎡/kg；The levigate treatment of row is bought to slag, its specific surface area is more than 300 ㎡/kg；Waterglass, modulus is 1.5.According to gangue：Flyash：Slag：Exciting agent waterglass=2：1：1：0.56 just proportioning mixing.
Added in the mixture for having matched natural sand, coarse aggregate, it is last then poured toward mixing external excitation agent solution, mixing water in mixer and being stirred until homogeneous, conserve, be molded.
