討されている。2. Description of the Related Art Road pavement surfaces in cold regions are severely worn by tire chains, spiked tires, and the like, and as a result, repairs and maintenance of the roads are expensive. In addition, it has been pointed out that dust has an adverse effect on the human body and a fear of environmental pollution. Therefore, in recent years, pavement using a concrete block for wear-resistant pavement has been studied.

付け強度に大きな問題がある。As a concrete block for wear-resistant pavement, a concrete block whose surface is impregnated with an acrylic resin and a concrete block whose surface is bonded with resin concrete or mortar containing steel fibers are known. However, since these concrete blocks for wear-resistant pavement are manufactured by performing post-processing on concrete blocks manufactured in a predetermined shape, the manufacturing process is complicated and the cost is high. Furthermore, in resin impregnated concrete blocks, it is difficult to control the thickness of the impregnated resin layer at a constant level, which results in variations. Unevenness is created. In addition, a concrete block to which resin concrete or mortar containing steel fibers is adhered has a large problem in adhesion strength.

重量部である。BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, cement and aggregate are essential components, and the ratio is 350 to 600 parts by weight of aggregate with respect to 100 parts by weight of cement, and the particle size in the aggregate is 2 parts. The proportion of coarse aggregate of 0.5 mm or more is 60 to 70% by volume. Here, the reason why the amount of the aggregate is set to 350 to 600 parts by weight with respect to 100 parts by weight of the cement is that if the amount of the aggregate is as small as less than 350 parts by weight, the viscosity of the concrete increases and it becomes difficult to mold. Conversely, if the amount of aggregate exceeds 600 parts by weight, cement paste cannot be sufficiently filled between the aggregates, and the strength becomes low. Here, a more preferable ratio is 400 to 550.

This is because the amount of wear increases, and conversely, if the amount exceeds 70% by volume, the amount of wear increases. here,
A more desirable ratio is 62 to 68% by volume.

的な実施例を挙げて本発明を説明する。In the method for producing a concrete block (particularly, a concrete block for pavement) according to the present invention, the above-mentioned materials are blended in the above-mentioned ratio and kneaded. The method of kneading may be any method, but it is convenient to use a forced stirring mixer or the like usually used for relatively stiffening. Next, the kneaded concrete material is subjected to vibration molding. Preferred vibration molding conditions include, for example, a frequency of 45.
00 to 9000 rpm, vibration acceleration is 10 to 209 g,
The vibration time is a time at which the concrete filling rate becomes 95% or more. The concrete block thus vibrated is cured to become a product. As a method of rehabilitation, curing may be performed by leaving the composition at room temperature, or may be performed by steam remediation, underwater curing, or spray curing. Hereinafter, the present invention will be described with reference to specific examples.
