Abstract

PROBLEM TO BE SOLVED: To provide a porous retaining wall material which has high water permeability and is produced by a production process that comprises using molten incineration slag discharged in an incineration process of general waste, as a raw material, adding cement, water, an inorganic binder and an organic binder to the molten incineration slag, mixing them together to form a super stiff-consistency mix, charging the mix into a form of any of large-sized concrete blocks (2 t, 4 t and 6 t), and hardening the charged mix while applying pressure to the charged mix with an intensive vibrator. SOLUTION: This production process of such concrete blocks comprises: mixing a mixed material consisting of molten slag and crushed stone with 15% of cement, 5% of water, 0.3% of an inorganic binder and 0.6% of an organic binder on the basis of the weight of the mixed material, to form a mix; and charging the mix into the respective forms of the concrete blocks.

の節約となる。[Problems to be Solved by the Prior Art and the Invention] A feature of the present invention is to produce granulated slag, crushed slag obtained by quenching slag obtained by melting wastes with water, and cement. Water is pressurized and hardened with a vibrating force of a vibrator to mix a mixture of 300 m to 350 kg of cement to 1 m 3 of the molten slag and a weight ratio of water to the cement of 30 to 40%. The effect of use is as follows. In other words, since molten slag obtained by melting general waste such as municipal waste, sewage sludge, and industrial waste is used, the raw material cost is extremely low, and the waste treatment and resource saving are extremely effective. . Furthermore, since it is a cement hardened material, not only heat energy for molding is not necessary, but also equipment for production can be simplified. More importantly, the molten slag originally has a large coarse particle ratio, that is, the coarse aggregate of natural river sand and sea sand has a coarse particle ratio of about 2.3 to 3.0. Slag coarse grain ratio is 3.0
When the cement is added and the molding is performed under the above-mentioned component ratio and pressurized state, no special particle size adjustment for satisfying the strength is required. This is an effective means for realizing a recycling-oriented society by manufacturing large-sized stacked blocks (porous), which are cheaper than conventional products, and by recycling resources. In addition, since it is a porous product, there is no need to drain water from the building block, there is no need for centralized drainage, there is no water pressure on the building block, and water can be drained in a natural state. The construction of drain pipes from the factory was carried out, but this product can drain the entire stacking block and save construction costs.

きるようになった。It is considered that the molten slag particles are originally glassy, have a moderately angular shape, and have an appropriate size. It has a high compressive strength, and thus can be obtained as a raw material without any special processing. In terms of safety, it has become possible to provide large-sized blocks (porous) that are excellent in safety.

350 kg and a weight ratio of water to cement of 30 to 40% are mixed and mixed, and the mixture is hardened by pressurizing with vibrating force using a powerful vibrator. The operation and effect are as follows. In the production of this large stacking block (porous), simply mix molten slag, cement and water at an appropriate mixing ratio, pressurize with vibrating force, and naturally cure in the air.
A block (porous) having a sufficient compressive strength can be obtained, and it is possible to mass-produce a large-sized block (porous) which is extremely simple in terms of equipment and labor and excellent in safety.
