Abstract
The invention relates to a water retention reinforcing agent of permeable concrete. The water retention reinforcing agent capable of prolonging the opening time of construction comprises powder and emulsion, wherein the powder comprises: 70-80% of silica fume, 5-10% of fumed silica, 6-10% of water reducer powder, 8-12% of dispersible emulsion powder and 1.0-1.5% of polyacrylamide; the emulsion is water soluble acrylic emulsion. A preparation method of the powder comprises the following steps: fully pre-mixing measured polyacrylamide and water reducer to form premix; and sequentially adding measured 50% of silica fume, fumed silica, dispersible emulsion powder, mixture of polyacrylamide and water reducer and 50% of silica fume and stirring the mixture with a gravity-free mixer for over 10min, so as to obtain the powder. The emulsion is added into mixing water in advance, and suspension liquid formed is taken as the mixing water of the permeable concrete.
Description
Technical field
The present invention relates to a kind of pervious concrete water retention enhancing agents.
Background technology
In recent years, with the continuous propulsion of Process of Urbanization Construction, the problem that urban construction brings increasingly manifests.Current 70%
Fluid-tight " death " the property hardened ground covering of urban ground, causes serious ecological disruption and brings urban waterlogging, noise, raises
The problems such as dirt.Water-permeable cement concrete has permeable, ventilative, sqouynd absorption lowering noise, reduces airborne dust, purifying water body, improves urban surface
Ecological environment of soil, alleviation rainwash and urban heat land effect, can easily realize arbitrarily devised effect.Can be widely applied to people
Trade, shopping mall, lightweight road, the small internal road in park, large-scale square, various new sports places, parking lot, underground are built
Engineering is built, dykes and dams, shore protection and freeway road shoulder bank protection etc. is constructed.The effective a variety of difficulties solved in Process of Urban Development
Topic, is the important paving material of sponge urban construction.
Aggregate, Binder Materials, water, water retention enhancing agents that water-permeable cement concrete is matched somebody with somebody by specific level etc. are in specific proportions through spy
The celluar concrete with continuous hole that different technique is made.Current water-permeable cement concrete generally existing low intensity, construction are opened
Put the time it is short the problems such as, be restrict water-permeable cement concrete widespread adoption principal element.
The content of the invention
Pervious concrete intensity can be improved it is an object of the invention to provide one kind, strengthens pervious concrete mixture water conservation
Property, construction open hour pervious concrete water retention enhancing agents long.
Pervious concrete water retention enhancing agents of the invention, are made up of pulvis and the component of emulsion two, and the emulsion is water solubility
Acrylic emulsion；The pulvis is by silicon ash, aerosil, water reducer pulvis, dispersibility latex powder, polyacrylamide group
Into, each component by weight percentage, respectively silicon ash 70%-80%, aerosil 5%-10%, water reducer pulvis 6%-
10%th, dispersibility latex powder 8%-12%, polyacrylamide 1.0%-1.5%.
Wherein, silicon ash selects the silicon powder of normal production, and dioxide-containing silica keeps drying, nothing more than 90%
It is granular；Aerosil is general industry level aerosil；Water reducer pulvis is concrete polycarboxylate water-reducer powder
Agent；Polyacrylamide is 15,000,000 anion-polyacrylamides from molecular weight.
Pervious concrete water retention enhancing agents preparation method of the invention is：The polyacrylamide and water reducer that will first measure
Pulvis is fully pre-mixed, and forms premix；Put into successively again measure 50% silicon ash, aerosil, dispersible
Property latex powder, polyacrylamide and water reducer compound, 50% silicon ash, using agravic blender stirring more than 10min obtain final product.
Usage amount and application method：Water retention enhancing agents pulvis usage amount is the 2%- of Binder Materials quality in concrete proportioning
3%；Emulsion usage amount is the 0.5%-2% of Binder Materials quality.Application method is：During stirring, by obtained water retention enhancing agents pulvis
Mixer is put into the lump with other raw material, stirring 1min or so is done, and water retention enhancing agents is well mixed with remaining raw material；Will
In the mixing water that emulsion input is measured, emulsion is formed emulsion with mixing water, finally add the mixing water containing emulsion
Mixer continues to stir 1-2min.
The special water reinforcing agent beneficial effect of pervious concrete of the invention is：
1. water-permeable cement concrete intensity can be significantly improved, its compression strength is reached more than 30MPa；
2. mixture water-retaining property can be significantly improved, concrete mix workability is kept, its construction open hour is extended to
More than 2h, can meet colorful water-permeable cement concrete and concentrate premixing, transport and machine spreading requirement；
3. preparation cost is low, prepares easy, it is easy to which large-scale promotion is used.
Specific embodiment
Embodiment
Pervious concrete water retention enhancing agents pulvis is prepared according to following proportioning：Silicon ash 70%, aerosil 10%, water reducer powder
Agent 8.5%, dispersibility latex powder 10%, polyacrylamide 1.5%, emulsion pours into the full water of composition in the mixing water for measuring.Using
Following match ratio prepares water-permeable cement concrete：Cement 380kg/m3, water retention enhancing agents pulvis 8kg/m3, water retention enhancing agents emulsion
7.6kg, 5-13mm rubble 1600kg/m3, water 106kg/m3.Wherein cement is PO42.5 and Portland cement, and water conservation increases
Strong agent is that, using special water retention enhancing agents obtained in said ratio, rubble is 5-13mm particle size range lime stone matter rubbles, mix
Water is ordinary tap water.The side that mixture is used after manually plugging and pounding after placing 1.5h under 20 DEG C of environment plus plate vibrator vibrates
Formula is molded, and compressive strength test is carried out after 28d, and compression strength reaches 35.5MPa.Coefficient of permeability reaches 2.0mm/s.
