Description
Technical field
The invention belongs to new material technology field, and in particular to a kind of elastic concrete.
Technical background
With the development and the improvement of people's living standards of urban construction, it is intended that the leisure such as sports ground, exhibition center is good for
The ground in body recreation place has certain elasticity and silencing function.Some paving sports field plastic cement race tracks at present, it is main
It is polyurethane material to want component, and cost is high.
At the same time, as the fast development of auto industry, the generation and accumulation of a large amount of waste and used rubber tyres have been formed
Serious " black pollution ".Waste old material is processed, is incorporated into concrete, can not only solve waste old
Pollution problem to environment, and can be very good to utilize this flexible characteristic of rubber powder, prepare with good
The concrete of elasticity.Chinese patent《A kind of special concrete using waste and old rubber particle and steel slag particle as aggregate》(application number
CN200910087111.X a kind of special concrete using waste and old rubber particle and steel slag particle as aggregate, including water) are disclosed
Mud, water reducer, mineral admixture, sand, steel slag particle, rubber grain and water, each component are by mass fraction proportioning：Cement 100
Part, 0.1~3 part of water reducer, 0~50 part of mineral admixture, 0~600 part of sand, 200~400 parts of steel slag particle, rubber grain 15
~50 parts, 20~80 parts of water.Two kinds of discarded objects of waste and old rubber particle and slag are added in concrete by the present invention simultaneously, can be with
It is a large amount of to utilize discarded object, improve natural environment, absorb free calcium oxide in steel slag using the elastic characteristic of waste and old rubber particle
Swelling stress so that slag is available without specially treated, and the volume stability of material on the whole is good；And because add
Waste and old rubber particle, its elasticity is higher than normal concrete, but the rubber grain that this method preparation uses is less, finite elastic,
And the inorganic material compatibility such as rubber grain and cement is bad, caking property is low, the intensity that influences concrete, impermeability and closely knit
Property.
