Abstract
The invention relates to anti-corrosion pervious concrete for highway engineering, and belongs to the technical field of building materials. The pervious concrete for highway engineering consists of the following materials in percentage by weight: 20-25% of gelled materials, 1.0-1.2% of calcium-rich powder, 5.0-6.0% of slag aggregate, 20-25% of steel slag aggregates, 2.5-3.2% of additives and the balanced coarse aggregates. On the premise that porosity and permeation coefficient of the anti-corrosion pervious concrete are obviously higher than those of the conventional pervious concrete, and compressive strength of the anti-corrosion pervious concrete is still higher than that of the conventional pervious concrete. Anti-corrosion performance is high, and the service life is prolonged obviously.
Description
Technical field
The invention belongs to the technical field of construction material, more particularly, it relates to a kind of highway engineering is with permeable
Concrete.
Background technology
In the past urban road construction typically adopted common concrete, and the road surface formed due to which is impermeable and collects rain
Water, and it is strong to the reflexive of heat, it is easily caused the environmental problems such as rain water-harvesting, tropical island effect.And adopt pervious concrete come
Laying bypass, the road surface such as bicycle lane are one of effective ways for solving the above problems.Pervious concrete is that a kind of macropore is mixed
Solidifying soil, is typically gathered materials as skeleton using specified particle diameter, and cementing material is wrapped in surface of aggregate as glued layer, formed skeleton-
The loose structure of hole.Compared with Common Concrete Pavement, porous pavement has larger porosity, can put aside more heat
Amount, is conducive to eliminating " tropical island effect ", and can collect and permeate rainwater, advantageously reduce urban waterlogging and improve soil, together
When also help absorption noise, with good ecological effect and social benefit.
Pervious concrete is typically made up of Binder Materials, coarse aggregate, water and additive.Wherein, fine aggregate is not spiked with, or
The fine aggregate of doping is less, so that whole concrete road surface porosity is very high, so as to water energy enough permeates rainwater and absorbs storage
Deposit heat.But equally it is that its intensity is generally also poor as the porosity of pervious concrete is higher, and the corrosivity of salt tolerant
Difference, so as to its durability is not good, needs frequent maintenance compared to common concrete road surface, in addition the fortune of pervious concrete
Defeated and molding is also more difficult.
