摘要： PURPOSE:To carry out the immediate removal of a PC product by a method wherein water is previously absorbed into an absorbent polymer which does not gel but keeps its independent form even when absorbing water, and the polymer absorbing water is mixed with a cement, an aggregate, and an admix ture, and the mixture is placed in a form and vibrated. CONSTITUTION:A molding form 10 consists of an inner form 14 and an outer form 16 which are coaxially disposed. A concrete 40 is placed into a space part 18 between the both forms 14, 16. Water is previously absorbed into a special water absorbent polymer which does not gel but keeps its independent form even when absorbing water. The concrete 40 is composed of the mixture of the polymer absorbing water, a cement, an aggregate, and an admixture. The placed concrete 40 is vibrated by a vibrator 22 mounted on the outer form 16. In this manner, water in the water absorbent polymer is exuded to make the concrete warkable. The concrete 40 is contacted and pressurized by a pressurizer 24, therefore being acceleratedly set. Therefore, the concrete 40 has a sufficient removal strength and can be immediately removed as a PC product.

摘要： PROBLEM TO BE SOLVED: To provide a fiber-reinforced heat insulating material which is improved in adhesiveness between a surface of a building skeleton and an outer finish material, and to provide an outside insulation structure and a method for executing the outside insulation structure. SOLUTION: According to the method for executing the outside insulation structure, the fiber-reinforced heat insulating material 10 having reinforcing fibers 12 buried therein is interposed between the surface of the building skeleton 2 and the outer finish material such as a tile. By virtue of the interposition of the heat insulating material 10, the adhesiveness between the surface of the building skeleton and the outer finish material is improved. As a result, employment of the outer finish material 8 is not necessarily limited to a lightweight one or employment of the heat insulating material is not necessarily limited to one having high strength, which contributes to reduction in construction cost.

摘要： PROBLEM TO BE SOLVED: To provide a lamination type method for manufacturing a PC panel which prevents occurrence of an initial freezing damage in the winter season or the like and enables attainment of a sufficient concrete strength. SOLUTION: After concrete C is placed in a form 1, a vacuum mat 5 is laid on the concrete C and a vacuum suction hose 7 is connected thereto so as to conduct an operation of sucking bleeding water on the surface of the concrete. After the sucking operation is completed, the vacuum mat 5 is removed, an insulating material 10 having an electric heater 12 incorporated is laid and the electric heater 12 is made to heat so as to ensure the shape retention of a PC panel. With the insulating material 10 left on the PC panel of which the shape retention is ensured, each of the aforesaid processes of placing the concrete, laying the vacuum mat, laying the insulating material and ensuring the shape retention is repeated sequentially and thereby a plurality of PC panels are manufactured in lamination in the same form material 1. The concrete is cured by heating by leaving the electric heater 12 heating also after the shape retention is attained, so as to ensure the concrete strength of the PC panel and to improve the speed of production.

摘要： PROBLEM TO BE SOLVED: To provide a simple and convenient formaldehyde scavenger capable of applying even on an existing room surface as a post-treatment without taking much time and excellent in workability. SOLUTION: The formaldehyde scavenger is formed by adding a formaldehyde scavenger composed of a composition prepared by carrying an aromatic or are aliphatic primary amine or the salt on a clay mineral into a surface treating agent such as a coating material or a wax to be applied on the existing room surface. As a result, formaldehyde is scavenged and removed only by applying on the existing room surface and even in the case of intending to remove formaldehyde after the completion of interior finishing work in the room, the formaldehyde scavenger is simply and conveniently applied with easy working sense as the post-treatment by the excellent workability, with which the surface treating agent itself is provided.

摘要： PROBLEM TO BE SOLVED: To surely synthesize a plurality of different functional layers by enhancing the anchoring effect so as to prevent occurrence of peel-off of mortar. SOLUTION: A double surface fastener 3 formed of a base sheet 3a having opposite surfaces at which several piles 3b are raised is applied to the inner surface of form for forming the outer surface side of a concrete body 1. By placing concrete, the double surface fastener 3 is integrally incorporated with outer surface of the concrete body while the piles on one side thereof are embedded in the concrete surface. After withdrawal of the form 2, mortar is applied to the outer surface of the body concrete is applied over the outer surface of the double surface fastener 3 so that the piles 3b on the other surface of the fastener are anchored in the mortar.

摘要： PROBLEM TO BE SOLVED: To provide a fitting method and structure of an inexpensive finish member which is easily executed and which can greatly increase, the separation strength of the finish member having a different coefficient of thermal expansion from the substrate concrete and absorb the difference in the thermal expansion by isolation of both materials. SOLUTION: Naps 14b protruding to one face side of a napped cloth 14 are integrally pushed in a substrate concrete face 11 and the naps 14c protruding to the other face side are integrally stuck on the rear face of the finish member with an adhesive to join the substrate concrete 11 and the finish member 12. In this way, the thread part 14a of the napped cloth functions as an isolation layer to absorb the difference of thermal expansion of the substrate concrete 11 and the finish member 12 and the napped parts of both faces integrally joined with the substrate concrete and the finish member function as anchors. Since a number of naps are erected closely, the connection strength of the substrate concrete and the finish member is stuck and fixed uniformly as much as possible on the whole surface and hence, the separation strength is remarkably increased.

摘要： PROBLEM TO BE SOLVED: To decrease force applied to a concrete member for mold releasing and to prevent the concrete member from breaking during mold releasing by laying a vacuum mat on the inner bottom face of a form and dehydrating under vacuum through the vacuum mat from the bottom face of a concrete after the concrete is fed. SOLUTION: A vacuum mat 14 is laid on the surface of a molding bed 10 and left and right side boards 16 are arranged on the periphery and each vacuum suction hole 12 is connected to a vacuum pump 20 through a vacuum hose 18. Before the concrete is fed, star lap strings 24 with a rectangular frame- like shape are arranged by penetration on the left and right side boards 16 and in addition, iron strings 26 are arranged on the center 10a of a form bed 10. After above described preparative works, the concrete is fed and after feeding of the concrete is completed, the vacuum pump 20 is immediately operated to suck and remove water in the concrete C through the vacuum mat 14 to the vacuum suction hose side 18. This suction operation is continued until curing in the form is completed. After the concrete is cured, notch-core 28 and both side boards 16 are removed, and cut parts of a molded article 30 are raised on its both side parts to make a completed state of the product.

摘要： PROBLEM TO BE SOLVED: To increase adhesion strength between a cement matrix and reinforcing fiber. SOLUTION: In this production method, a reinforcing fiber 10 of a short fiber state is coated with a latent hardening type epoxy resin 12. The epoxy resin 12 consists of a liquid resin main agent and a hardening agent coated with a fine microcapsule film. The reinforcing fiber 10 is mixed and stirred with cement C, fine aggregate S and water in a stirring tank 16 to produce a fiber reinforced mortar 18. The obtd. mortar 18 is poured into a mold 20 and left to stand in the mold for preageing. After hardening of the mortar starts, the fiber-reinforced mortar 18 is aged by heating by using a heater 22 disposed above the mortar 18.
