Accompanying drawing explanation
Fig. 1 is the preparation technology flow chart that the mine tailing waste residue of the present invention substitutes concrete prepared by flyash and fine aggregate.
Detailed description of the invention
Below in conjunction with embodiment, the mine tailing waste residue of the present invention is substituted flyash and concrete prepared by fine aggregate is made into one Step explanation:
The present invention proposes a kind of mine tailing waste residue and substitutes concrete prepared by flyash and fine aggregate, this concrete resource Recycling mine tailing waste residue, reduces the pollution problem to environment, alleviates the concrete depletion rate to natural resources, and concrete is every Performance (workability, mechanical property and endurance quality etc.) index meets standard-required.Present invention achieves recycling solid Body garbage, reduces the pollution to environment, saves natural resources, also reduces concrete production cost, and preparation technology is simple, side Just, Social benefit and economic benefit is notable.
The concrete that the mine tailing waste residue of the present invention substitutes flyash and prepared by fine aggregate comprises cement, breeze, admixture, thin Gather materials, natural rubble, water and water reducer.Wherein, admixture and fine aggregate are that the Machine-made Sand formed pulverized by mine tailing waste residue.Wherein water Mud uses P O42.5 Portland cement.Water reducer is the existing water reducer in market, any one.Mine tailing waste residue is excellent Elect granite quarrying waste as.Mine tailing waste residue uses sand system processed through crushing, at shaping processing according to its physical and chemical performance Make after reason particle surface smooth, without sharp corners, the Machine-made Sand (0mm-5mm) that granule-morphology is good, property indices accord with Close " regular concrete sand, stone quality and test method standard " JGJ52 working standard requirement.In prepared Machine-made Sand, < The stone powder shape Machine-made Sand of 0.16mm substitutes flyash and is used as admixture, it is preferable that the Machine-made Sand of >=0.16mm is used for substituting all Natural sand is used as fine aggregate, in other embodiments, it is also possible to substitutes more than 80% natural sand and is used as fine aggregate.In Machine-made Sand, Mass content shared by the stone powder shape Machine-made Sand of < 0.16mm is 10%~20%.The strength grade of concrete being configured to be C20~ C40, workability, mechanical property and endurance quality etc. meet standard-required.
Preparation technology is as shown in Figure 1: mine tailing waste residue uses sand system processed through crushing, makes after shaping processed Grain smooth surface, without sharp corners, the Machine-made Sand that granule-morphology is good, Machine-made Sand is sieved, the stone powder shape of < 0.16mm is machine-processed Sand is used as admixture, and the Machine-made Sand of >=0.16mm is used as fine aggregate, using water, cement, breeze, machine as admixture and fine aggregate Batching pressed by sand processed, natural rubble and water reducer, stirs, and is then discharged into agitator truck, product control of dispatching from the factory, and is transported to execute Work building site.
Beneficial effects of the present invention is embodied in:
(1) present invention uses mine tailing waste residue for replacing flyash, and flyash rise in price on market can be avoided to cause mixed The problem that solidifying soil cost increases, it is also possible to when avoiding flyash on market supply falls short of demand, concrete improves what cement consumption caused Cost increases;
(2) present invention uses mine tailing waste residue to replace natural sand as concrete fine aggregate, the minimizing exploitation to natural river sand Amount, the depletion rate of the non-renewable resources that slow down, reduces the risk of the river levee collapse caused because of exhaustive exploitation;
