Abstract
The invention discloses a kind of ordinary mortars containing recycled fine aggregate, it is characterised in that including following parts by weight substance：Cement：210 parts；Flyash：90 parts；Recycled fine aggregate：150 600 parts；Artificial sand：900 1350 parts, for the recycled fine aggregate obtained by discarded concrete Mechanical Crushing, the grain size of the recycled fine aggregate is 1.9mm.The property indices of the ordinary mortar containing recycled fine aggregate of the present invention meet the requirement that relevant criterion, specification, engineering use, reduce building castoff direct emission amount, it is both economically and environmentally beneficial, solve the problems, such as the dismounting to inhering architecture (works), improvement project growing day by day and generating discarded concrete can not deal carefully with, and the tensile bond strength of the ordinary mortar containing recycled fine aggregate is apparently higher than the ordinary mortar of no recycled fine aggregate.
Description
Technical field
The present invention relates to a kind of ordinary mortar, specifically a kind of ordinary mortar containing recycled fine aggregate.
Background technology
According to incompletely statistics, in municipal solid wastes, building castoff accounts for about 40% or so, and wherein discarded concrete accounts for
The 30%~40% of building castoff discharge capacity, and with the quickening of urbanization process in world wide, to existing building
The dismounting of object (works), improvement project it is growing day by day, can all make the yield of discarded concrete more and more.With city
Expanding economy, the quantity of discarded concrete can be increasing, and will be increasingly tight the problem of how to handle discarded concrete fragment
It is high.
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 is regenerated
Application of the fine aggregate in ordinary mortar is relatively fewer.
Invention content
According to the technical issues of set forth above, and provide a kind of ordinary mortar containing recycled fine aggregate.The present invention utilizes
Discarded concrete crushes the recycled fine aggregate substitution part artificial sand of generation, prepares ordinary mortar, used technological means is such as
Under：
A kind of ordinary mortar containing recycled fine aggregate, it is characterised in that including following parts by weight substance：
Cement：210 parts；
Flyash：90 parts；
Recycled fine aggregate：150-600 parts；
Artificial sand：900-1350 parts.
The recycled fine aggregate is obtained by discarded concrete Mechanical Crushing.
The grain size of the recycled fine aggregate is 1.9mm.
The recycled fine aggregate：150 parts；The artificial sand：1350 parts.
The recycled fine aggregate：300 parts；The artificial sand：1200 parts.
The recycled fine aggregate：450 parts；The artificial sand：1050 parts.
The recycled fine aggregate：600 parts；The artificial sand：900 parts.
The property indices of the ordinary mortar containing recycled fine aggregate of the present invention meet relevant criterion, specification, engineering
The requirement used reduces building castoff direct emission amount, both economically and environmentally beneficial.
The present invention can be widely popularized in fields such as architectural engineerings for the foregoing reasons.
Specific embodiment
A kind of ordinary mortar containing recycled fine aggregate, including following parts by weight substance：
Cement：210 parts；
Flyash：90 parts；
Recycled fine aggregate：150-600 parts；
Artificial sand：900-1350 parts.
The recycled fine aggregate is obtained by discarded concrete Mechanical Crushing.
The grain size of the recycled fine aggregate is 1.9mm.
The recycled fine aggregate：150 parts；The artificial sand：1350 parts.
The recycled fine aggregate：300 parts；The artificial sand：1200 parts.
The recycled fine aggregate：450 parts；The artificial sand：1050 parts.
The recycled fine aggregate：600 parts；The artificial sand：900 parts.
Embodiment 1
A kind of ordinary mortar containing recycled fine aggregate, including following parts by weight substance：
Cement：210 parts；
Flyash：90 parts；
Recycled fine aggregate：150 parts；
Artificial sand：1350 parts.
The recycled fine aggregate is obtained by discarded concrete Mechanical Crushing.
The grain size of the recycled fine aggregate is 1.9mm.
Embodiment 2
A kind of ordinary mortar containing recycled fine aggregate, including following parts by weight substance：
Cement：210 parts；
Flyash：90 parts；
Recycled fine aggregate：300 parts；
Artificial sand：1200 parts.
The recycled fine aggregate is obtained by discarded concrete Mechanical Crushing.
The grain size of the recycled fine aggregate is 1.9mm.
Embodiment 3
A kind of ordinary mortar containing recycled fine aggregate, including following parts by weight substance：
Cement：210 parts；
Flyash：90 parts；
Recycled fine aggregate：450 parts；
Artificial sand：1050 parts.
The recycled fine aggregate is obtained by discarded concrete Mechanical Crushing.
The grain size of the recycled fine aggregate is 1.9mm.
Embodiment 4
A kind of ordinary mortar containing recycled fine aggregate, including following parts by weight substance：
Cement：210 parts；
Flyash：90 parts；
Recycled fine aggregate：600 parts；
Artificial sand：900 parts.
The recycled fine aggregate is obtained by discarded concrete Mechanical Crushing.
The grain size of the recycled fine aggregate is 1.9mm.
1kg is respectively taken to add water the ordinary mortar containing recycled fine aggregate that embodiment 1-4 is obtained and pass through mortar mixer
Stirring, mixing time are no less than 3min, obtain sample 1-4,
Sample 5 includes following parts by weight substance：Cement：210 parts；
Flyash：90 parts；
Recycled fine aggregate：0 part；
Artificial sand：1500 parts.
The consistency 92mm of sample 1, water-retaining property 92.0%, setting time 5.5h, 14d tensile bond strength 0.34MPa,
The consistency 99mm of sample 2, water-retaining property 91.7%, setting time 5.6h, 14d tensile bond strength 0.37MPa,
The consistency 94mm of sample 3, water-retaining property 92.4%, setting time 5.9h, 14d tensile bond strength 0.42MPa,
The consistency 99mm of sample 4, water-retaining property 91.6%, setting time 6.1h, 14d tensile bond strengths 0.44MPa.
The consistency 90mm of sample 5, water-retaining property 91.5%, setting time 5.4h, 14d tensile bond strengths 0.32MPa.
Tensile bond strength is common (plastering) mortar of reaction and the adhesive property of structure (wall), its direct shadow of height
Ring the construction bond quality (including cohesive force, apparent mass, hollowing or cracking etc.) to common (plastering) mortar, particularly mortar
Cohesive force, mortar bonding power is smaller, and phenomena such as hollowing, pitted skin, crack and come off more easily occurs in wall body structure.It can be seen that：
Ordinary mortar (sample 1-4) containing recycled fine aggregate is apparently higher than the ordinary mortar (sample 5) of no recycled fine aggregate.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
