Description
Technical field
The present invention relates to building material technical field, be specifically related to a kind of high permeable retardation setting type concrete additive and preparation method thereof.
Background technology
Along with develop rapidly and the quickening of urban construction paces of China's economy, the ground in city is covered by buildings and concrete road surface gradually, and permeable tree and grass coverage is fewer and feweri, and fluid-tight earth's surface brings many negative impacts to the ecological circulation in city.Because ground lacks water-permeable, rainwater can not permeate the ground, and causes the exchange of city heat, moisture to lack, causes city temperature, humidity is difficult to normal regulating, create city " heat island phenomenon ".Meanwhile, because rainwater can not permeate the ground at short notice, a large amount of rainwater can only enter river by underground drainage facility, not only increases the burden of pumping equipment, and chance rainstorm weather very easily causes urban waterlogging, causes serious potential safety hazard to city management.At the beginning of 21 century, China concrete field technician begins one's study application pervious concrete, and in park, equivalent-load burden requirement not high region in walkway starts progressively to use.Pervious concrete is a kind of coarse porous concrete, and the general greater particle size that adopts gathers materials as skeleton, and utilize consolidating material to be wrapped in surface of aggregate and form skeleton, the hole utilizing skeleton to produce reaches the object of infiltration.Chinese invention patent CN102898062A discloses the special composite additive of a kind of cobble model pervious concrete, ultra-fine microballon, silicon ash, lithium ground-slag, polyoxyethylene are complex as a kind of additive by this invention, the parcel of cement slurry to cobble surface is increased by the viscosity and water-retentivity that improve cement slurry, improve cobble surface adhesion performance with this, ensure concrete water-permeable and mechanical property.Although this invention makes the water-permeable of pervious concrete and intensity obtain certain improvement, composite additive also counteracts that permeable hole while improving cobble cementability, very easily blocks bottom hole, affect water permeability when slurry sinks flowing.
In addition, due to construction technology many employings pumping-up method of large-span steel pipe concrete, thus there is higher requirement to concrete material, there is good pumpability, extra retarded set characteristic and self-compacting ability, also needed to possess certain powerful feature morning simultaneously.But single concrete material system obviously cannot meet above-mentioned requirements.In order to ensure the concrete serviceability of metakaolin and hardening characteristics, research is had in system, to add high efficiency water reducing agent and super-retarder as composite additive, but this kind of compound additive likely occurs with between cement the problem that adaptability is bad, and likely there is the effect of interference mutually with the admixture used in construction process.
Therefore, in order to solve concrete water-permeable and intensity, improving the over-all properties of pervious concrete, can use in high-load road, in the urgent need to a kind of easy to use, pervious concrete specialist additive that intensity, wear resistance, water permeability are good.
