に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention enables a water-permeable pavement having a high strength and a large resistance to drying shrinkage by mixing and kneading only a certain amount of water without mixing various constituent materials at the site of a water-permeable pavement construction. The present invention relates to a water-permeable pavement composition and a water-permeable pavement method.

抗も必ずしも一定していなかった。2. Description of the Related Art Conventionally, in water-permeable pavement construction, generally, mortar or concrete mainly composed of Portland cement is mixed at the construction site where water-permeable pavement is to be made, and then the mixture is applied to the construction site. However, in the case of such a method, it is generally approved, but the work becomes complicated, and since the water amount adjustment to the cement is not constant, there is a large variation in the water permeability of the mortar or concrete, and thus to the mechanical strength and drying shrinkage. Resistance was not always constant.

る方法がある。On the other hand, in order to improve the water permeability of mortar or concrete used for water permeable pavement, a specific admixture is added to a mixture mainly composed of Portland cement, or the aggregate in the mixture is limitedly mixed. As a result, means for increasing water permeability have been proposed. According to such a proposal, in order to fix the water cement ratio (W / C), for example, after the cement-sand or aggregate for enhancing the water permeability is mixed, that is, after the porosity after hardening is set to 15 to 35% by volume. There is a method of using ice chips, a method of adding asphalt emulsion or water-dispersible synthetic resin, a water-dispersible rubber, etc. as an admixture, a method of admixing a cellulosic thickener for mortar, and what is an admixture method? Another method is to prepare an aggregate having an extremely large difference in particle size.

調合する水分量が使用するポルトランドセメントや骨材
に付着する水分量と調整し難い欠点がある。However, when ice pieces are used as a part of water, it has the effect of keeping the water-cement ratio low and constant, but since the cement hardening reaction starts in the low temperature range, the hardened product is white. It often causes sinter and has a drawback that the amount of water prepared separately from ice pieces is difficult to adjust with the amount of water attached to the Portland cement or aggregate used.

する欠点がある。When an asphalt emulsion is used as an admixture, the porosity is lowered due to the effect of the emulsifier used and the initial water permeability is impaired. In addition, asphalt is fused due to an increase in temperature. There is a drawback that the water permeability is gradually lowered.

It has the drawback of causing a decrease.

A water-permeable pavement capable of providing a water-permeable pavement having high mechanical strength and large dry shrinkage resistance only by mixing and kneading a certain amount of water with the composition. It is the one trying to solve the method.

Aggregate 1400 to 1600 parts by weight, water-soluble or water-dispersible cement admixture powder 0.5
The present invention is to devise a composition for water-permeable pavement comprising 5 to 5 parts by weight, and when the composition is used at a construction site, a water-cement ratio (W / C) of 30 to 40% is used. By mixing and kneading, and then applying it to a predetermined part, it was possible to obtain a water-permeable concrete having stable performance.

ては機械的強度が低下し不安定になる。The dry crushed stone aggregate, which is the other main component of the water-permeable concrete, must have as little adhered water as possible in order to prevent the Portland cement from solidifying over time, and the amount thereof was dried at 105 ° C. The amount is 3% by weight or less, preferably 2% by weight or less with respect to the aggregate.
If the amount of adhered water exceeds 3% by weight, the cement is likely to solidify, and when the water is kneaded and then rolled by a roller or the like, the dispersion of the aggregate in the concrete becomes large, and the mechanical strength decreases. And become unstable.

度が低下する傾向がある。As the dry crushed stone aggregate, crushed stone is used from an economical point of view, and even if gravel of the same grain size is used, it is all right, and what is important is to use the crushed stone of No. 6 to No. 7 grain size. In particular, it is preferable that the diameter of about 7 to 12 mm is at least 80% by weight. The dry crushed stone aggregate is 1400 to 1600 parts by weight when obtaining 1 m 3 of water-permeable concrete. 1400
If it is less than 1 part by weight, it is difficult to obtain a porosity suitable for maintaining water permeability, and if it exceeds 1600 parts by weight, the mechanical strength tends to decrease.

As a result of trial and error, it was concluded that it is optimal to make the composition of the present invention in the form of a premix together with Portland cement and aggregate in a dry state.

Although the result was obtained that it is suitable as a constituent component of the composition of the invention, it was found that particularly water-soluble or water-dispersible polymer powders can provide appropriate water permeability and improve mechanical strength, and in particular, polymer dispersion, In particular, it was found that the vinyl acetate or acrylic thermoplastic resin emulsion significantly improves the mechanical strength and leads to the stabilization of the strength. Together, it was found that the amount of water soluble or water dispersible polymer powder should be at least 70% by weight.

It is necessary that the content be below, and if the content of water exceeds 2% by weight, moisture in the air is easily attracted and the uniformity of the water-permeable concrete is likely to be impaired.
