The invention discloses a production process of novel cobblestone prefabricated members. The production process comprises the technical process of the novel cobblestone prefabricated members. Different shapes and sizes of molds are made according to the demands of customers, patterns are firstly drawn or etched on the molds in advance, cobblestones are tightly arranged according to the patterns ofthe molds to make the molds full of the cobblestones, then the molds are fully filled with concrete grout or a colloidal material, the colloidal material concrete grout or colloidal material on the surface layers of the cobblestones are removed after the molds are turned over to make the middle-upper portions of the cobblestones exposed, the cobblestone prefabricated members to be parqueted are taken out of the molds and then are packaged and encased after complete drying and solidification. The parqueted cobblestone prefabricated members are spliced into a cobblestone path, the production process has the advantages of being simple and convenient to construct, high in construction speed, free of environmental pollution and the like, and the parqueted cobblestone prefabricated members hasthe lots of advantages that the prefabricated members are excellent in quality, high in artistry, good in flatness, high in ornamental value, capable of making water seep and friendly to the environment, damaged parts in the using process are convenient to replace and the like.

Production process of novel cobblestone prefabricated members

PURPOSE: A method for manufacturing fiber attached blocks is provided to prevent fiber materials from being separated and to prevent thermal deterioration of block concrete. CONSTITUTION: A method for manufacturing fiber attached blocks comprises following steps. Filaments are spread on a lower molding which forms a front side of a block body (10). A mortar layer is formed on the filaments while high early strength mortar is placed on the filaments and the filaments are cured. The block body is cured after the concrete is placed into a mold.

PROBLEM TO BE SOLVED: To provide a water-retaining laying member for greening, capable of preventing noxious insects from settling therein, capable of holding water retaining properties, light weight and therefore portable, capable of being cut into a necessary size, and capable of being used as a shelf member, an edge member, a laying member around a roadside tree, etc. SOLUTION: This laying member is produced by adding small amounts of pulverized coal and water to a mixture of chaff and cement, kneading them, so as to form a muddy admixture, then coating one or both of surfaces of a meshwork member with the admixture, and drying the coated member.

PROBLEM TO BE SOLVED: To provide a molding of a carbonized product in which useful functions of the carbonized product such as a deodorizing function and a function of adsorbing a substance can be exhibited satisfactorily without raising the manufacturing cost. SOLUTION: The porous molding of the carbonized product having ≥20% porosity is manufactured by bonding slender pieces of the woody carbonized product to one another by using a cement-based binder having the fineness of ≥5,000 cm 2 /g specific surface area and molding the bonded pieces into a predetermined shape.

Concrete interlocking block for air purification and road using charcoal

PROBLEM TO BE SOLVED: To provide a concrete block having high vegetation power and excellent in water and air purification powers. SOLUTION: Into a mold 4 for wedge block, a common concrete, which comprises portland cement and forms wedge block body, is poured; a porous concrete is poured on it; further a charcoal-containing concrete, which contains a large amount of bamboo charcoal, is poured on the porous concrete; and these are fastened and solidified. The charcoal-containing concrete 3, which contains large amount of charcoal on its surface, porous concrete parts 2, which encloses the charcoal and has a thickness of about 10 cm, and common concrete parts 1 are integrally molded. The obtained concrete block has a large amount of spaces having excellent water permeability, air permeability and root penetrability in its inner part, and it has excellent water retainability and high vegetation power.

PROBLEM TO BE SOLVED: To enable purification of water, air and environment by compounding portland cement with specific amounts of powdery wooden carbide and fine aggregate, kneading the compound with a prescribed amount of water and hardening the compound. SOLUTION: Portland cement in an amount of 100 pts.wt. is mixed with 15-35 pts.wt. powdery wooden carbide and 40-15 pts.wt. fine aggregate and the mixture is kneaded with water. Thereby, product capable of mixing a large amount of wooden carbide therein, free from brittleness and having strength which is equivalent to that of normal concrete is obtained. Purifying force of water and air is increased by including a large amount of wooden carbide and parasitism of microorganism is promoted by porous structure of coal to increase biological purifying force. As the wooden carbide Charcoal, activated carbon, etc., can be used and bamboo coal having resource recovering force is preferable and the particle diameter of the bamboo coal is practically about 5 mm. Sand is generally used as the fine aggregate.
