Abstract
The present invention discloses a green compound admixture prepared by using construction waste recycled fine powder. The green compound admixture consists of construction waste recycled fine powder, fly ash and slag powder, and the construction waste recycled fine powder comprises concrete recycled fine powder and brick recycled fine powder. The green compound admixture product can consume a greater amount of construction waste, and provides a high additional value resource utilization mode for the construction waste; in the admixture stock product, the solid waste content is greater than or equal to 40%, and the admixture has significant resource-saving and environment-friendly benefits. Moreover, the green compound admixture can exert a composite effect among various binding materials and has a positive effect on concrete properties, although the anti-carbonation property of the green compound admixture concrete is slightly reduced, the working property of the green compound admixture is certainly improved, the mechanical properties such as compressive and splitting strength are free of significant differences with plain concrete, and the anti-penetration performance of chlorine ion is improved.
Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of green composite blend utilizing construction refuse regenerated micro mist to prepare.
Background technology
Along with the continuous quickening of urbanization process, generation and the quantity discharged of urban building waste are growing.It is quite large that urban building waste accounts for municipal solid wastes proportion, is about 30% ~ 40% of city solid waste total amount.Adopt air storage or land-fill method to dispose, take big area on the one hand and plough, great negative impact can be caused to vegetation, HUMAN HEALTH, human settlement on the other hand, cause the destruction of ecotope.Therefore, building waste safe disposal and comprehensive utilization are subject to people's attention day by day.
The current recycling approach of current building waste is very single, and the added value utilized is not high.The invention provides regenerative micro powder and flyash that a kind of utilization is processed into by building waste, slag micropowder is composite is prepared from.This green composite blend can relatively largely be dissolved building waste, for building waste provides the recycling approach of a high added value.
Summary of the invention
The object of this invention is to provide the method being mixed the green composite blend of composite preparation by concrete regenerating micro mist (or brick regenerative micro powder) and flyash, slag micropowder by suitable ratio.
Technical scheme of the present invention is:
A green composite blend prepared by construction refuse regenerated micro mist, mixed by construction refuse regenerated micro mist, flyash and slag micropowder and form, described construction refuse regenerated micro mist comprises concrete regenerating micro mist and brick regenerative micro powder;
When described construction refuse regenerated micro mist is concrete regenerating micro mist, described green composite blend is made up of the raw material of following mass percent:
Concrete regenerating micro mist 15%-25%, flyash 15%-25%, slag micropowder 50%-70%, be designated as the green composite blend of C type;
When described construction refuse regenerated micro mist is brick regenerative micro powder, described green composite blend is made up of the raw material of following mass percent:
Brick regenerative micro powder 15%-25%, flyash 35%-45%, slag micropowder 30%-50%, be designated as the green composite blend of Type B.
The green composite blend specific surface area of described C type is at 600m
2/ more than kg, size-grade distribution meso-position radius D50 are 17-20 μm, D90 is that 60-65 μm, 28d activity index reaches more than 70%.
The green composite blend specific surface area of described Type B is at 600m
2/ more than kg, size-grade distribution meso-position radius D50 are 10-15 μm, D90 is that 30-40 μm, 28d activity index reaches more than 70%.
The green composite blend of building waste of the present invention is theoretical for instructing with the mutual synergistic effect of polynary gelling material, construction refuse regenerated micro mist (concrete regenerating micro mist or brick regenerative micro powder), flyash and slag micropowder is formed so that suitable proportioning is composite.Every physical and chemical performance index of products C type (the green composite blend prepared by solidifying native regenerative micro powder) and Type B (the green composite blend prepared by brick regenerative micro powder) adulterant product substantially all higher than regenerative micro powder, flyash, close to slag micropowder.This green composite blend product can be relatively large building waste of dissolving, for building waste provides the recycling mode of a high added value; In this adulterant product, volume >=40% of solid waste, has obvious resources conservation and environmental benefit.Simultaneously, this green composite blend can play the composite overlay effect between each gelling material, actively impact is produced on concrete performance: green composite blend concrete is except anti-carbonation properties reduces slightly, its serviceability has certain improvement, resistance to compression, split mechanical property and normal concrete no significant differences such as drawing, Anti-Chloride Ion Penetration makes moderate progress.
