摘要： PROBLEM TO BE SOLVED: To improve weather resistance against an alkali, ultraviolet rays or the like by regulating a mortar-cement ratio and a sand-cement ratio so as to be each within a specific range, adding a specified amount of a polymer, and using a polymeric staple as a reinforcing fiber. SOLUTION: This composition for an imitation stone is obtained by regulating the water-cement ratio in a mortar so as to be 25-35%, and the sand-cement ratio so as to be 50-120%. The polymer in the proportion of 3-7% based on the weight of the cement in the mortar is added thereto. A polymeric staple such as a vinylon fiber is preferably used as the reinforcing fiber to reduce the deterioration caused by the alkali of the cement component. The reinforcing fiber in the proportion of 2-8% based on the weight of the cement in the mortal is preferably added thereto. If necessary, an air-entraining agent can be added to the composition to miniaturize the babbles included in the component and to increase the resistance to freezing and thawing.

摘要： PROBLEM TO BE SOLVED: To prevent propagation to an imitation rock material of a crack even when the crack occurs in a hydraulic material by forming an easily deformable flexible layer between the hydraulic material and an imitation rock. SOLUTION: In the method, an imitation rock material 10 is installed beforehand at a specified place before the construction of a concrete structure. A flexible layer 12 is formed on the rear side of the imitation rock material 10. The flexible layer 12 has waterproofness and deformation following properties as seen in urethane, asphalt, etc., and is applied on an imitation rock factory and an execution field. When the imitation rock material 10 is assembled, steel materials 14 for a timbering are mounted on the rear side of the imitation rock material 10, anchor materials 16 are set up among the imitation rock material 10 and the steel materials 14, and the imitation rock material 10 is supported. When the assembly and installation of the imitation rock material 10 are completed, concrete C for forming the new concrete structure is placed on the rear side of the imitation rock material 10. When placed concrete C is cured, the concrete structure is built while the imitation rock material 10 unified on the surface side of the concrete structure is mounted.

摘要： PURPOSE: To obtain a sample for the display, excellent in transparency, stable with time, high in safety, and capable of being taken out without damaging the display article and without breaking the article during the production and after displayed. CONSTITUTION: The sample 10 for the display is produced by disposing a display article, the replica 14 of sea weed growing on a reel, in a cylindrical acrylic resin transparent container 12 and sealing the transparent container 12 with a silicone gel 16A. The silicone gel 16A is formed by disposing the replica 14 of the display sea weed in the transparent container 12, filling a silicone gel raw material into the transparent container 12, and subsequently curing the filled raw material.

摘要： PROBLEM TO BE SOLVED: To suppress a craze separation of a joint. SOLUTION: A bogus rock 10 comprises a plurality of bogus rock panels 12, backing materials 14 cured after the materials 14 are charged on back surface sides of the panels 12, and joint materials 16 charged in an interval 15 between the panels 12. In a joint structure of the rock 10, isolating materials 28 are interposed between the curable joint material 16 such as a mortar or the like filled in the intervals 15 and the materials 15.

摘要： PURPOSE:To improve property of execution, moldability, safety, grade of appearance and durability. CONSTITUTION:A backing is formed by a three-dimensional knitting texture which has a thickness of 0.7 to 20mm and which comprises matrix structures 32, 34 on front and back sides, at least one of the matrix structures 32, 34 having mesh-shaped or groove-shaped voids, and connection threads 36 connecting the matrix structures 32, 34 to each other. A material comprising cement or resin or a mixture thereof as a main agent is filled in and covers the backing for molding. A coating material gets into the voids of the three- dimensional knitting texture to exhibit a firm anchoring effect and a bridging effect, thereby preventing peeling, falling and crack of the coating material.
