Abstract
The invention discloses a recycled aggregate concrete preparation method and relates to the technical field of building raw materials. The method adopting the key technology of 'waste use' includes the steps: using building wastes such as waste concrete, waste bricks and waste lime-sand mortar which are smaller than 690mm in length as raw materials, determining the quantity of the raw materials as required, crushing and drying to enable moisture to be not more than 0.5% prior to gradational sieving, removing metal with magnets and removing wood dust, plastics and sundries according to the specific weight during gradational sieving so that recycled aggregates with the grain sizes of 0.3-0.6mm, 0.6-1.18mm, 1.18-2.36mm and 2.36-4.75mm are prepared, and then the recycled aggregates are mixed with broken stones, cement, pumping agents, retarders and water according to scientific proportion so that the recycled aggregate concrete of various grades in each recycled aggregate concrete model series is prepared. The recycled aggregate concrete is used as the building raw materials. The recycled aggregate concrete preparation method has the advantages that natural resources are protected, labor and time are saved, cost is low, wastes are turned to wealth, the requirements of low-carbon production and low-carbon life are met, and the method makes contributions to sustainable development.
Description
Technical field
The preparation method of regenerated aggregate concrete of the present invention relates to building materials technology field; Be particularly related to building materials raw material technical field; Be specifically related to preparing method's technical field of regenerated aggregate concrete.
Background technology
With regard to building materials and building materials raw material; Everybody is not strange; Specific to concrete, premixing mortar, extraordinary mortar, air-entrained concrete building block, urban pavement brick; Everybody is not strange yet, and especially specific to " concrete " that use for building, all many is basic raw material with cement and river sand.Along with the fast development of urban construction, the demand of concrete and mortar is increased day by day, and then the exploitation of river sand is also increased day by day, resource is limited after all, river sand also can be fewer and feweri thereupon, more will drop into lot of manpower and material resources.River sand (promptly by salvaging the sand of coming out in the ship Congjiang, river, the lake, its price is very high), river sand will be dried before using simultaneously; Because river sand water cut is 98%, about moisture approximately 70-80%, produces and to be less than 0.5% behind the natural air drying with the sand water cut; So river sand dried to spend a large amount of expenses; Not only consume a large amount of coal resources, freight charges are high, and substantial appreciation of prices.Simultaneously, on the other hand, the old building removal amount in city is increasing, and the waste after no doubt removing is also more and more, and concentrated stacking has taken increasing soil.The get off dumping of building of existing removal is increasing, handles seldom, and solid refuse is such as concrete, masonry etc.; Be difficult for decomposing, pass through the long duration and could natural decomposition fall, even be used for filling out hole, laying; Also can be excessive and can't dissolve owing to volume, not only the land occupation resource also is unfavorable for environmental greening; And of long duration, bury in underground, be unfavorable for vegetation growth and hinder soil to the filteration of underground water resources etc.Conclusion is got up, and existing known technology with deficiency, defective and drawback that present situation exists is: on the one hand, waste natural resource, time-consuming effort and increased extra-expense, price constantly rises violently and expense is high; On the other hand, refuse accumulation progressively increases and can't dissolve, the land occupation resource, environment impacted; All do not meet the requirement of low-carbon (LC) production and low-carbon (LC) life.Seeing that contriver's expertise is with abundant working experience and to the excelsior unremitting pursue of cause; The present invention is exactly conscientious and on sufficient investigation, understanding, analysis, summary, the above-mentioned existing known technology of research and the present situation basis; With " utilization of waste material " gordian technique, deficiency, defective and drawback that existing known technology and present situation exist succeed in developing in order to overcome and to solve.Through the present invention, make refuse obtain reasonable utilization, turn waste into wealth, meet environmental protection, reduced expense significantly, accomplished the life of low-carbon (LC) production and low-carbon (LC), made for Sustainable development contribution should have been arranged.
Summary of the invention
The present invention is with " utilization of waste material " gordian technique, and the preparation method of regenerated aggregate concrete is provided, and on the basis that makes " regeneration aggregate " building material raw produce, " each grade concrete of each cement range of models of regeneration aggregate " is provided; The present invention is being raw material less than the waste concrete of 690mm, useless brick, antiquated sand ash building castoff; Set amount on demand; Dry moisture again and carry out the grade screening after smaller or equal to 0.5% through pulverizing; In the grade screening process, using magnet removes metal and removes wood chip and plastics and foreign material with the mode of proportion size; Thereby be prepared into the regeneration aggregate that particle is 0.3-0.6mm, 0.6-1.18mm, 1.18-2.36mm, 2.36-4.75mm, add rubble with regeneration aggregate and add cement and add pumping agent and add each grade concrete that scientific matching that retardant adds water is processed each cement range of models of regeneration aggregate.
The purpose that reaches through the present invention is: on the one hand, the protection natural resource, saving of work and time is laborsaving and eliminate extra-expense, the price that do not receive resource influences and expense is low; On the other hand, effectively dissolve refuse and turn waste into wealth, save land resources, effectively protect environment; Reduce cost and accomplish the requirement that meets the life of low-carbon (LC) production and low-carbon (LC).
