Abstract
The invention discloses a non-bearing recycled fine aggregate concrete perforated brick. Raw materials comprises, in parts by weight, 20-25 parts of cement, 40-50 parts of recycled fine aggregate, 20-30 parts of fly ash, 5-7 parts of montmorillonite, 8-10 parts of natural river sand, 0.1-0.2 part of a water reducer, and 0.2-0.4 part of a foaming agent. The recycled fine aggregate is obtained by directly performing crushing and filtering processing on waste concrete, and the particle size of the recycled fine aggregate is less than 5 mm. The raw materials are mixed and stirred uniformly, and then the obtained mixture is squeezed for forming an adobe, and finally steam maintenance is performed. By employing waste concrete, resource is saved, and secondary pollution problem of waste concrete on environment is solved, and the perforated brick possesses the characteristics of light weight, low drying shrinkage, large anti-dismantling strength and the like.
Description
Technical field
The present invention relates to building material technical field, be specifically related to a kind of non-bearing recycled fine aggregate concrete perforated brick.
Background technology
In recent years, world architecture industry enters the high speed development stage.Concrete is as the most large artificial material taking and also having caused the discussion of sustainable development to the negative impact that environment causes natural resources.The quantity of the waste and old concrete of the waste and old concrete that the world removes every year, the discarded concrete of new building generation and concrete plant, the discharge of prefabricated structure factory is huge.Meanwhile, estimate that discarded concrete quantity discharged is by the quickening along with urbanization process in world wide from now on, the dismounting of inhering architecture, transformation are grown with each passing day.The traditional treatment process of discarded concrete is mainly transported to countryside and is stacked or landfill, not only to spend a large amount of freight charges, cause secondary pollution to environment, and a large amount of valuable land resources will be taken, and to abandon simply be also significant wastage to natural resources.The development and application of regenerated aggregate concrete, solves on the one hand the problems such as a large amount of discarded concrete difficult treatment and the ecotope that causes thus go from bad to worse; On the other hand; natural aggregate is substituted with building waste recycled aggregates; the consumption of construction industry to natural aggregate can be reduced; thus the exploitation reduced natural sandstone; fundamentally solve scarcity and a large amount of Exploit sand and stone day by day of natural aggregate to the destruction of ecotope; protect the living environment of the mankind, meet the requirement of Sustainable development.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of non-bearing recycled fine aggregate concrete perforated brick, adopts discarded concrete, economizes on resources, solve discarded concrete causes secondary pollution problem to environment; Have lightweight, drying shrinkage is low, anti-tear the features such as intensity is large open.
A kind of non-bearing recycled fine aggregate concrete perforated brick, raw material (by weight) adopts cement 20-25 part, recycled fine aggregate 40-50 part, flyash 20-30 part, polynite 5-7 part, natural river sand 8-10 part, water reducer 0.1-0.2 part, whipping agent 0.2-0.4 part, described recycled fine aggregate is directly obtained after fragmentation, filtration treatment by the concrete discarded, the granular size of described recycled fine aggregate is less than 5mm's, described raw material makes adobe through extrusion molding again after mixing and stirring, finally carries out vapor cure.
As a further improvement on the present invention, described cement adopts Tangshan tower slag 32.5 difficult to understand class g cement.
As a further improvement on the present invention, the granular size of described recycled fine aggregate is 3-4mm.
As a further improvement on the present invention, described flyash is II grade of flyash of Dagu power plant.
Compared with prior art, tool of the present invention has the following advantages and beneficial effect: adopt discarded concrete as the raw material of recycled fine aggregate, economize on resources, use polynite improve product thermostability, anti-tear intensity open, recycled fine aggregate concrete perforated brick has the features such as lightweight, pollution-free, good stability.
