摘要： PROBLEM TO BE SOLVED: To enhance the durability of a concrete structure by modifying the surface of concrete within a usual execution range without requiring the extension of a term of works or special disposition (e.g., the installation of a scaffold, the adjustment of surface moisture quantity of concrete or the like).
SOLUTION: First, a concrete form 1 is assembled. Succeedingly, the surface of the concrete form 1 coming into contact with concrete is coated with colloidal silica 2. Herein, the colloidal silica 2 on the concrete form 1 is applied by a method capable of ensuring a constant film thickness such as spraying, brush coating or the like. Next, concrete 3 is cast in the concrete form 1 coated with the colloidal silica 2 and aged for a definite period. Thereafter, the concrete form 1 is detached and, at this point of time, the surface of concrete 3 is modified.

摘要： PURPOSE:To provide a structure in which water squeezed from a raw cement mortar material and once sucked into a water squeezing and sucking chamber can be prevented from reversely flowing into vacuum suction holes even when the sucking action is stopped. CONSTITUTION:A plurality of vacuum suction holes 3 are provided on a molding face of an upper mold 1. The vacuum suction holes 3 are opened opposed to a water squeezing and sucking chamber 2. The water squeezing and sucking chamber 2 is connected to a vacuum blower disposed outside a device. In this constitution, a water content of a raw cement mortar material 6 is sucked. In this cement mortar molding device, opening parts 31 of the vacuum suction holes 3 are disposed higher than the bottom of the water squeezing and sucking chamber 2.

摘要： PURPOSE:To produce a cement molded object having an undercut like complicated recessed part by a press molding method. CONSTITUTION:A core 4 set to a diameter expanded state by sealing a liquid 42 in a rubber bag 41 composed of a magnetic material is temporarily mounted on the core temporary mounting part 21 of a metal net 2 by the magnetic force of the rubber bag 41. A cement molding material 5 is supplied to a lower mold 12 and a mold 1 is closed to perform dehydration press molding. The mold is opened to release the temporary mounting state of the core 4 and the metal net 2. The rubber bag 41 of the core 4 of the aged and cured cement molded object is torn to draw out the sealed liquid 42 and the rubber bag 41 is removed to obtain a cement molded object having a complicated recessed part.

摘要： PURPOSE: To remove an intergranular phase of presenting a problem of an irregularity while avoiding the irregular problem by hot pressing a body object in the presence of a permeable substance for receiving at least part of an intergranular phase substance. CONSTITUTION: An object 21 to be hot pressed is filled in a die 22. A ram 23 is disposed on the object 21 and underneath the object 21. A pressure is applied to the object 21 during hot pressing by using the ram 23. A filling implement 24 is introduced between the object 21 and a die wall 25. The implement 24 is corrected to be easily conformed between the wall 25 and the object 21 to avoid an outside lateral movement or deformation of the object. In this case, sintering is conducted in the presence of the permeable substance corrected to receive an intergranular phase. In this method, at least part of the intergranular phase is transferred to the permeable substance. If the intergranular phase is received by the permeable substance, this can be absorbed by the substance and/or transferred.
