Abstract

The invention discloses a cement concrete with water permeability, comprising the raw material components with the weight ratio: 250-400 kg/m<3> of cement, water being 0.28-0.35 time of the cement, 1300-1800kg/m<3> of coal refuse slag, 25-40kg/m<3> of inorganic cementing materials and 0-3.0kg/m<3> of synthetic fiber; wherein, the grain diameter of the coal refuse slag is 5-12mm of single granularcomposition, and the crushing value is less than or equal to 30%. Compared with the prior art, as aggregate is made of the coal refuse slag instead of natural aggregate, and the screened coal refuse slag has a certain strength as well as porosity and activity which are higher than those of the natural aggregate, the prepared cement concrete with the water permeability can be ensured to have betterquality, has high added value utilization of the coal refuse slag and lower cost, reduces the exploitation for the natural aggregate, and is beneficial to ecological environment balance.

Description

Cement concrete with water permeability
Technical field:
The present invention relates to a kind of cement concrete with water permeability.
Background technology:
Along with the shortage day by day of the energy, some alternative energy begin to utilize.Coal gangue is used as a kind of low grade coal at present more and more widely; Yet the slag that coal gangue burning back produces reaches more than the few hundred thousand tonnes of as the annual quantity discharged of solid waste; If can carry out regenerated using to these solid waste, on the basis that does not reduce performance, be used for road pavement, not only practice thrift cost; Reduce building waste and clear and processing costs, also can alleviate the refuse pollution in city.But present coal gangue slag; Reason such as assorted owing to its source, that Classification Management is lack of standardization and quality control is not strict; The activity of having only the pulverous coal gangue slag of few part to be used as cement is referred and synthesized agent, and most coal gangue slag can only be used for low value-added utilizations such as pit backfill.What simultaneously present cement concrete with water permeability adopted is natural aggregate, and cost is higher and be unfavorable for the ecotope balance.
Summary of the invention:
The purpose of this invention is to provide a kind of with coal gangue slag do to gather materials high value added utilization, cost is lower and help ecotope equilibrated permeable concrete.
Be to realize the object of the invention, used technical scheme is: a kind of cement concrete with water permeability, and it comprises, and cement, water, coal gangue slag gather materials, inorganic jointing compound and synthon, and the weight proportion of each feed composition is: cement 250～400kg/m 3, water is 0.28～0.35 times of cement, coal gangue slag 1300～1800kg/m 3, cement inorganic material 25～40kg/m 3, synthon 0～3.0kg/m 3, the grain diameter of described coal gangue slag is the single grating of 5～12mm, crush values≤30%, and described cement can be silicate cement or ordinary Portland cement, and label is not less than 52.5; Said cement inorganic material can be one or more the combination in silicon ash, zeolite and the metakaolin; Said synthon can be one or more the combination in polypropylene fibre, polyacrylonitrile fibre and the trevira, and length is 6mm～19mm.
Preferred as further, the weight proportion of said each feed composition can be: cement 280～380kg/m 3, water is 0.28～0.35 times of cement, the coal gangue slag 1350～1750kg/m that gathers materials 3, cement inorganic material 30～38kg/m 3, synthon 0～1.5kg/m 3
As most preferably, the weight proportion of said each feed composition can be: cement 350kg/m 3, water is 0.3 times of cement, coal gangue slag 1550kg/m 3, cement inorganic material 35kg/m 3, synthon 1.5kg/m 3
The present invention compared with prior art; Adopt the coal gangue slag alternative natural aggregate that gathers materials owing to gather materials; And the coal gangue slag that screens has certain intensity; The cement concrete with water permeability of preparation also has porosity and the activity higher simultaneously, so can guarantee the product preferable quality than natural aggregate.Therefore the present invention makes to gather materials high value added utilization with coal gangue slag, and cost is lower, and has reduced the exploitation to natural aggregate, helps the ecotope balance.
