Rubbish, wherein mainly discarded concrete.The discarded concrete that China generates every year also up to 13,600,000 tons, has accounted for municipal refuse
40% or so of total amount.Not only appropriation of land, consuming transport power also create environmental pollution for the stacking of discarded concrete, alkaline to give up
Slag makes soil " inactivation ", and the approach that recycles of discarded concrete also needs to continually develop.
In addition traditional mortar material generally comprises cement, water, river sand etc., in order to improve the intensity of building structure screed
And crack resistance, it can also often add gypsum, lime paste or fibrous reinforcing material.The building table built using cement mortar
Face is being able to maintain that some strength, but with the extension of time, situations such as being susceptible to the accumulation of salt in the surface soil, cracking, leakage, peeling in early days.
On the one hand in waterwork engineering, the concrete in positions such as overfall dam dam facing, water-conveyance tunnel, spillway or protection-aprons, often
Be subjected to high-velocity flow or hold sand under the arm, stone high-velocity flow rushes mill, and the breakoff phenomenons such as abrasion, cavitation corrosion easily occur, it is not only direct or
Connecing influences the normal safe operation of engineering, and safeguards that renewal expense is huge.Existing resistant abrasion material is in construction process
The later stage performance for neutralizing scene exposes many problems, if silica flour series abrasion resistance concrete early strength is developed at a too fast speed, in
Later strength growth is small, and heat of hydration release is concentrated, and drying shrinkage and self-desiccation shrinkage are big, and crack easily occurs；Modified epoxy class resists
Frosted slurry and protective coating are rushed still containing more volatile solvents component, the easy act under moist and water environment does not have
It significantly improves, flexibility still is apparent not enough, easy hollowing, cracking and flaking.On the other hand, in the big of highway and tunnel
In development, there is also some technical barrier to be solved, such as the problem of bumping at bridge-head in subgrade location, highfill embankment
The freeze thawing of stability of slope problem, severe cold area breaks the repair of slope problem and Tunnel Engineering and bankets etc., these are all to coagulation
Soil sand slurry proposes higher requirement.
