Description
13364~2 The present invention relates to a cement concrete pavement which is so excellent in water-permeability that inl~rce~lion of water into the ground surface which has become a serious problem particularly in towns and cities can be s~lcces~fully avoided.
As the recent tendency of ur~ni7~tinn has progressed, the harmful influences of the urbanization have become remarkable in various fields.
Rain water which could permeate into the ground is now plt;vell~d from permto~ting into the ground and from being held in the ground by asphalt pavements, concrete pavements, various bllil(lings, and so on. Of those harmful influences of the urbanization, particularly the condition of such an impe liment of rain water permeation/holding into/in the ground has become a serious problem more and moreas the urbanization has progressed. That is, as the ground surface into which rain water can perm~t~ decreases, underground water decreases immediately so that theground subsides, the growth of trees becomes slow, or the ecology or or~ni~m~ inthe ground changes. Further, because of the above-mentioned decrease of water-permeable ground surface and difficulty in water holding in the vicinity of the ground surface, when rain falls concentratedly in short time even though the total rainfall is not large, rivers overflow or trafflc networks are disrupted and serious social problem is caused.
In a point of view different from the ro~t;going one, particularly recently, it has become aesthetically desirable to color sidewalks, public squares, etc.
At present, the method in which various pigments are mixed into asphalt or cement concrete in advance and such a mixture is kneaded when it is to be used or the method in which various pigment~ are sprayed onto a pavement surface are the main current in pavement coloring.
In view of the above-mentioned water-permeability and water-holding p-upelly, the realization of pavement excellent in water-permeability and water-holding property . ~
has been earnestly required and there has been proposed water-permeable asphalt to satisfy the requirement. However, the water-permeable asphalt is not always satisfactory because the water-permeability and water-holding plupelly thereof are not so excellent as they are expected, the asphalt is melted by slm~hine to cause loading to make the water-permeability more deteriorate, and time aging of strength of the asphalt is remarkable. Accordingly, water-permeable concrete using cement concrete has attracted attention, and provision of practical water-permeable concrete excellent in water-permeability and water-holding plupelly is expected.
Further, in view of coloring a pavement, such methods of pavement coloring as described above provide artificial visual feeling unlike natural colors and therefore it cannot but to say that those methods are successful in providing the Çolt;goillg "charm".
It is therefore an object of the present invention to elimin~tP the defects in the prior art as described above.
As the result of earnest investigation, the inventor of this application has succeeded in realization of a cement concrete pavement which is excellent in water-permeability and water-holding property and which is provided with naturalcolors, elimin~ting foregoing disadvantages in the prior art.
That is, according to the present invention, the cement concrete pavement is composed of a hardened cement concrete mixture in which 300 - 400 kg of portland cement, 0.008 - 0.04 weight portions of binder and 0.3 - 0.45 weight portions of water relative to 1 weight portion of the cement, and an aggregate compûsed of sand and No. 7 crushed stone at a weight ratio within a range of from 5: 95 to 20: 80 are subst~nti~lly uniformly distributed per volume of 1 m3 of the hardened cement concrete mixture, and in which a cement mortar portion ~flhering to a surface of the aggregate in a surface of the hardened cement concrete mixture is removed.
It is particularly preferable for the water-permeable cement concrete pavement to select the ratio of the sand to the No. 7 crushed stone to be within a range of from lO: 90 to 15: 85, because with the ratio in this range, the resulting strength is suitable for a vehicle traffic pavement and the water-permeability can be secured to a required extent.
Further, it is preferable to select the binder to be 0.015 - 0.03 weight portions relative to 1 weight portion of the cement or to select the water to be 0.35 - 0.40 weight portions relative 1 weight portion of the cement. The quantity of the binder t;senl~ the quantity of solid portion of resin in emulsion.
Further, in balance between strength and permeability, it is preferable to use the cement by an amount within a range of from 320 - 370 kg per 1 m3 of the water-permeable cement concrete.
According to the present invention, in an area of pavement on a sidewalk, a public square, or the like, an agglega~ exposed on the surface of the pavement exhibits a natural colour held by the aggregate per se through shot blasting tre~tm~nt, to thereby give aesthetic appeal unlike the co-lvel lional colored pavement which has given artificial visual feeling.
Further, because of the foregoing configuration, the water-permeable cement concrete pavement according to the present invention shows the same water-holding plopelly as that exhibited by ordinary soil in rain fall and realiæs rapid water-permeation which cannot be compared with the co-lv~ntional asphalt pavement or the conventional cement concrete pavement, while the water-permeable cement concretepavement according to the present invention has sufficiently large strength for practical use. In the cement concrete pavement according to the present invention, it is possible to obtain the rate of water permeation of the order of 10-l- 104 cm/sec, typically, of the order of 10-l - 10-3 cm/sec.
-~r The water-permeable cement concrete pavement according to the present invention is remarkably different from the conventional water-permeable asphalt pavement in that in the former, no loading is generated, time again is gentle, no melting is caused under the condition of a high ~~ ture, and so on.
Moreover, the water-permeable cement concrete pavement according to the present invention has eY~ee~ingly high voids of 10 - 30% in spite of its strength. As a result, even if fine earth and sand or the like are accumulated on the surface of the concrete pavement, the earth and sand can be passed through the voids when rain falls so that the pavement is cleaned without causing any loading.
The water-permeable cement concrete pavement according to the present invention has strength which is sufflcient for practical use while the pavement has the large voids and sufflcient water-permeability as described above. The compression strength of the concrete pavement is 200 - 300 kg/cm2 (the strength after 4 week~s curing in constant-l~lllpel~ture water of 20C), and the flexural strength thereof is 20 - 30 kg/cm2 (the strength after 4 weeks curing in constant-~lll~l~ur~ water of 20C).
The water-permeable cement concrete pavement according to the present invention is produced in the process comprising the steps of: kne~-ling, per lm3 of a cement concrete Illi~Ul'e, 300 - 400 kg of portland cement, 0.008 - 0.04 weight portions (solid portions) of binder and 0.3 - 0.45 weight portions of water relative to 1 portion of the cement, and an aggregate forming the balance being composed of sand and No. 7 crushed stone at the ratio within a range of S: 95 to 20: 80 by weight to thereby obtain a cement concrete mixture; pouring or injecting the thus obtained cement concrete mixture into a mold; hardening the cement concrete mixture to thereby form a concrete pavement; and washing the surface of the concrete pavement to remove cement mortar portions ~(lhering to the aggregate surface in the concrete pavement surface by using a grinding/sweeping machine (commonly-called a shot blasting machine).
i~
In the aggregate according to the present invention, it is necessary to select the weight ratio of the sand to the No.7 crushed stone to be within a range of from 5: 95 to 20: 80. The ratio of 5: 95 is suitable to produce a concrete pavement for sidewalk, while the ratio more than 10: 90 is suitable to produce a concrete pavement for light traffic. A part of the aggl~ale, preferably, 10 - 30 weight percent of the agglc~ale~ may be substituted by No.6 crushed stone having a particle size of 13 - 5 mm. In this case, there is a disadvantage in that the external appearance of the concrete pavement becomes poor because the large-sized No.6 crushed stone co-exists with the No.7 crushed stone, although there is an advantage in that the strength of the concrete pavement is increased to a certain extent.
The ~luanli~y of the portland cement is selected to be 300 - 400 kg, preferably,320 - 370 kg, per 1 m3 of the whole cement concrete ~ lu-~ including water. Binder is added by 0.008 - 0.040 weight portions, preferably, 0.015 - 0.03 weight portions, relative to 1 weight portion of the cement. As the binder, it is possible to use any binder which is known as a general additive to cement mortar. That is, natural or synthetic rubber, for example, SBR, NBR, acryl resin, epoxy resin, and the like, may be used as the binder. Generally, the binder is added in the form of emulsion. For example, when an SBR latex binder (JSR TOMAC SUPER, produced by Japan Synthetic Rubber Co., Ltd.: solid portion of 0.45%) available on the market is used by a quantity within the foregoing range, the flexural strength can be improved by about 10 - 60%. If the quantity of the binder exceeds the range, however, the water-permeability is undesirably considerably reduced.
The quantity of water is selected to be 0.30 - 0.45 weight portions, preferably,0.35 - 0.40 weight portions, relative to 1 weight portion of the cement. The water-permeability is poor if the quantity of water ~Y-~eeds the upper limit of the range, and on the contrary, sufficient knea~ling cannot be performed if the quantity of water is decreased beyond the lower limit of the range.
As the shot blasting m~tPri~l to be used for grinding/sweeping, for example, spherical iron (having a diameter not larger than about 2 mm) or sand (such as silica ~.
1336~2 sand or the like having a diameter not larger than 0.6 mm) is used. The shot blasting m~tPri~l is caused to collide with the cement concrete surface by using a grinder/sweeping machine to thereby remove cement mortar portions adhering to the aggl~gale.
As the recent tendency of ur~ni7~tinn has progressed, the harmful influences of the urbanization have become remarkable in various fields.
Rain water which could permeate into the ground is now plt;vell~d from permto~ting into the ground and from being held in the ground by asphalt pavements, concrete pavements, various bllil(lings, and so on.
