Description

A kind of new concrete

Technical field

The present invention relates to concrete field, in particular to a kind of new concrete.

Background technique

As country is to the control of environmental protection and to the protection of water resource, the exploitation of various regions strict control natural sand, naturally Sand is that supply falls short of demand in the market, is held at high price.China is in the epoch of big construction, great development, infrastructure, premises The use that construction all be unable to do without concrete is produced, this just needs to find out a kind of resource that can replace natural sand, while also to meet The requirement of environmental protection and energy saving.

Current main substitute is cleaned after being crushed using river cobble, and the exploitation of cobble causes certain wound to riverbed Evil, various regions strictly control.

Some areas replace natural sand using the aggregate chips of washing, and a large amount of waste residue is left after washing, produce a large amount of useless Water, but also will cause secondary pollution.

Summary of the invention

The present invention to solve the above problems, provide a kind of new concrete, using when mining production rubble through Vibration Screen Residue after point, replaces traditional natural sand, passes through incorporation variety classes additive or the usage amount coagulation of adjusting additive Native strength mark reaches C45, in the demand for having better meet user, reduces the production cost of enterprise.

In order to achieve the above objectives, the technical solution adopted by the present invention is that: a kind of new concrete, every cubic meter of concrete by 150-180kg water, 350-380kg cement, 50-70kg miberal powder, 45-60kg flyash, 600-700kg wind sand, 1000- 1200kg stone, the mixing of 7.5-8.5kg additive are made, wherein through vibrating when the wind sand is mining production rubble Residue after sieve screening, uses after high power vacuum cleaner collects ultra-fine grain in transmission belt, and selection fineness modulus is 2.6。

Further, the cement is ordinary portland cement.

Further, the stone particle grade is 5-31.5 continuous size fraction.

Further, the additive is III efficient retarding and water reducing agent of UC-.

Further, the water is 172kg, and the cementitious matter that the cement, the miberal powder, the flyash form is 480kg, the wind sand are 656kg, and the stone is 1092kg, and the additive is 8.2kg.

In conclusion the present invention has following advantages:

The residue when present invention uses mining production rubble after vibrating screen sieves, replaces traditional natural sand, passes through Incorporation variety classes additive or the usage amount concrete strength label for adjusting additive reach C45, use having better meet The demand at family reduces the production cost of enterprise.
