Abstract
Ordinary mortar of discarded concrete production and preparation method thereof is utilized the invention discloses a kind of.The ordinary mortar is made of according to parts by weight following component:40 60 parts of discarded concrete recycled fine aggregate;5 30 parts of cement;2 10 parts of flyash;10 30 parts of artificial sand;15 parts of additive;10 30 parts of water.The ordinary mortar that consistency, water-retaining property, mortar tensile bond strength and the compression strength of the ordinary mortar of the present invention are equivalent to or are produced higher than artificial sand, production requirement using recycled fine aggregate substitution artificial sand production ordinary mortar can be realized using the present invention, had good value for applications.
Description
Technical field
The present invention relates to building material technical field more particularly to it is a kind of using discarded concrete production ordinary mortar and
Preparation method.
Background technology
In municipal solid wastes, building castoff accounts for about 40% or so, and wherein discarded concrete accounts for building castoff
The 30%~40% of discharge capacity, and with the quickening of urbanization process in world wide, dismounting, transformation to inhering architecture
Engineering it is growing day by day, can all make the yield of discarded concrete more and more.
Regeneration thickness is used as after taking broken, cleaning, screening to the processing of discarded concrete and recycling majority both at home and abroad
Aggregate uses (and most of presence all in the form of coarse aggregate), and major part recycled aggregate is used in concrete at present, and by again
The ordinary mortar mechanical property of raw fine aggregate production is low, it is impossible to meet the requirement of relevant criterion, specification, engineering, discarded concrete
Application of the recycled aggregate in the production of ordinary mortar is relatively fewer.
Invention content
In view of above-mentioned problems of the prior art, the purpose of the present invention is to provide one kind, and there is higher mortar to stretch
Ordinary mortar for utilizing discarded concrete production of adhesion strength and compression strength and preparation method thereof.
Technical scheme is as follows:
A kind of ordinary mortar produced using discarded concrete, is made of according to parts by weight following component:
In the above-mentioned technical solutions, the discarded concrete recycled fine aggregate refers to discarded concrete is broken by machinery
The regeneration concrete obtained after broken, cleaning, screening, fineness modulus are 2.3~3.
In the above-mentioned technical solutions, the fineness modulus of the artificial sand is 2.5-2.8.
In the above-mentioned technical solutions, the additive is according to mass ratio 2-5 by naphthalene water reducer and organosilicon moisture repellent:
The compound additive that 5-10 is mixed to get.
In the above-mentioned technical solutions, the cement is portland cement.
The present invention also provides the preparation method of ordinary mortar described above, specially:According to parts by weight discarded concrete
Recycled fine aggregate, cement, flyash and artificial sand are poured into blender successively to be stirred, and then dissolves additive according to parts by weight
Yu Shuizhong pours into blender stirring.
Beneficial effects of the present invention:
Ordinary mortar water-retaining property, mortar tensile bond strength and the compression strength being prepared using the method for the present invention are suitable
In or higher than artificial sand production ordinary mortar, method using the present invention can realize using recycled fine aggregate replace artificial sand
The production requirement of ordinary mortar is produced, solves problem of environmental pollution caused by discarded concrete stacking, while can reduce to ore deposit
The consumption in goods and materials source, has many advantages, such as practical, easy to operate, energy saving, has good value for applications.
Specific embodiment
Following non-limiting examples can make those of ordinary skill in the art be more fully understood the present invention, but not with
Any mode limits the present invention.
The material that example below uses:
Discarded concrete recycled fine aggregate:The concrete that collection demolition of buildings is discarded from building site, by Mechanical Crushing, clearly
Wash, sieve after obtained regeneration concrete, fineness modulus 2.6.
