Abstract
The invention discloses a novel high-performance water-permeable concrete cementing agent which comprises 50-90 parts of magnesium ammonium phosphate cement, 10-50 parts of potassium magnesium phosphate cement, 2-15 parts of B2O3, 1-5 parts of fibers and 1-3 parts of pigment. Compared with a common water-permeable concrete, the water-permeable concrete prepared from the cementing agent provided by the invention has the advantages that the performance is higher and the deicer-scaling resistance and the wear-resisting property are high and excellent; after the water-permeable concrete is adopted for construction, no special maintenance is required; the traffic can be quickly opened; and the novel high-performance water-permeable concrete cementing agent can be widely applied to the fields of urban road engineering, landscape engineering, environmental engineering, and the like.
Description
Technical field
The invention belongs to road construction technical field, more particularly to a kind of high-performance permeable concrete cementing agent and its preparation
Method, the cementing agent can be widely used for urban road engineering, Garden Engineering and environmental project etc..
Background technology
Pervious concrete (Pervious Concrete) is aggregate, cement, water, additive and the mineral matched somebody with somebody by specific level
Admixture etc. has in specific proportions the celluar concrete of continuous hole made by Jing special process.The matter of current pervious concrete
Amount is very different, is primarily present problems with：1. pervious concrete low strength；2. wear-resistant and frost resistance is poor；3. it is durable
Property is poor, easily occur it is aging, the phenomenon such as crack and flake off；4. it is poor with the bond effect of cutting optimal.
The present invention is adopted can be with asphalt mixtures modified by epoxy resin lipid phase with high-strength, excellent frost resistance, good wearability and adhesion strength
The phosphate cement for matching in excellence or beauty as cementitious matter, by proportion optimizing, it is proposed that a kind of cementing agent prescription of high-performance permeable concrete
And its technology of preparing.
The content of the invention
Present invention aims to the deficiencies in the prior art, there is provided a kind of salt resistance is frozen, wear-resisting, high-strength new high property
Energy pervious concrete cementing agent and preparation method thereof.
The novel high-performance pervious concrete cementing agent of the present invention, including ammonium magnesium phosphate cement, potassium magnesium phosphate cement, B2O3、
Fiber and pigment, the mass fraction of each component is：
In above-mentioned technical proposal, described ammonium magnesium phosphate cement is made up of magnesia and ammonium phosphate salt.Described potassium phosphate
Magnesium cement is made up of magnesia and potassium phosphate.Described B2O3Introduced with boric acid or boratory form.Described fiber is poly-
Tacryl.Described pigment is the inorganic pigment such as natural minerals or metal oxide.
The method for preparing above-mentioned novel high-performance pervious concrete cementing agent is as follows：50～90 parts of ammonium phosphate are taken by quality
Magnesium cement, 10～50 parts of potassium magnesium phosphate cement, containing 2～15 parts of B2O3Boric acid or borate, 1～5 part of fiber and 1～3 part of face
Material, after mixing 10～30 minutes in batch mixer, makes finished product.
The application of novel high-performance pervious concrete cementing agent, it is characterised in that by cementing agent and stone dry mixing it is uniform after,
Once add water stirring 2～3 minutes, and water consumption is 0.10～0.15 with cementing agent mass ratio, obtains pervious concrete, pours front base
Layer be not required to watering wetting, after pouring, be not required to sprinkle water moisturizing, heating maintenance, can in 1～5h open to traffic.
The method and its construction technology for preparing high-performance permeable concrete using the cementing agent of the present invention is as follows：
1. by cementing agent and the stone dry mixing of the present invention it is uniform after, the stirring that once adds water 2～3 minutes can acquisition high-performance
Pervious concrete, its water-cement ratio (water consumption and cementing agent mass ratio) preferred value is 0.10～0.15, is preferably stirred using forced action type
Machine is stirred；
2. before pouring, basic unit be not required to watering wetting, by base cleaning it is clean after, the pervious concrete being stirred directly is spread
It is flat；
3. gently shaken the pervious concrete compound after paving with plate vibrator, should not strongly be vibrated or be tamped；
4. after vibrating, further should be flattened using solid steel tube or the compacting of light-duty road roller；
5. construct after the completion of, be not required to special curing, can in 1～5h open to traffic.
The high-performance permeable concrete prepared using the cementing agent of the present invention has advantages below and using effect：
1. intensity is high, can quick open to traffic；
2. it is high with the adhesion strength of base material；
3. very excellent frost resistance and deicer-scaling resistance performance；
4. good resistance to stress fatigue capability；
5. volume stability is good, drying shrinkage very little, good endurance.
Specific embodiment
Embodiment 1
Embodiment 2
Embodiment 3
As known from Table 1, compared with common pervious concrete material, the pervious concrete prepared using cementing agent of the present invention
Combination property is significantly superior, not only possesses higher intensity, and with good permeable effect, while wearability and frost resistance
It is also significantly better than common pervious concrete.
The performance of pervious concrete of the present invention is can obviously improve by optimizing material mixture ratio, by reduction water-cement ratio, suitably
Improving fibers content and rationally reduce stone consumption can improve pervious concrete intensity of the present invention, while concrete frost resistance and resistance to
Mill property is also accordingly improved；By increasing B2O3Consumption, the operable time of pervious concrete of the present invention can be improved；By adjusting
The ratio of ammonium magnesium phosphate cement and potassium magnesium phosphate cement, it is ensured that the excellent frost resistance of pervious concrete, while also having good
Resistance to water；Therefore, it can the design requirement and field condition according to pervious concrete, the permeable coagulation for selecting cost performance optimum
Native match ratio.
The different ratio pervious concrete Performance comparision of table 1
Note：1. control sample is common pervious concrete, adopts Portland cement for cementitious matter；
2. frost resistance is compression strength loss rate after 25 Frozen-thawed cycleds；
3. the intensity data of control sample be 28 days anti-folding (pressure) intensity, the intensity number of embodiment 1, embodiment 2 and embodiment 3
According to for 7 days anti-folding (pressure) intensity.
