摘要： PROBLEM TO BE SOLVED: To evaluate workability of concrete by using filling properties of high-fluidity concrete capable of being constructed without compaction.
SOLUTION: A reduced model using a homothetic ratio set in consideration of a structure and construction conditions is made by confirming the structure and construction conditions of a concrete structure to be constructed. A slump flow value of the concrete is changed so that a prescribed flow slope can be obtained, through the use of a flow slope of the concrete which is placed as an index into a flow-reduced model; a concrete placing experiment is performed so that the performance of the filling properties of the high-fluidity concrete can be confirmed; and the workability of the concrete structure is evaluated.

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： PROBLEM TO BE SOLVED: To easily introduce prestress with a desired value without requiring a large-sized machine.
SOLUTION: An earth retaining wall of a vertical shaft, which is provided to oppose earth pressure or water pressure from surrounding natural ground, is divided into a plurality of wall parts along a circumferential direction; the respective wall parts are formed in such an arched shape as to overhang to an outer peripheral side in a plan view; corner parts 113 are formed between the arched wall parts; and the adjacent corner pats 113 are tightly tied by a tie bar 1. When installed between the corner parts 113, the tie bar 1 is installed in a state of being heated up to a prescribed temperature by a sheet heater 5. After installation, when the temperature of the tie bar 1 falls up to an ordinary temperature, the tie bar 1 is contracted by a temperature difference; consequently, even if a very strong tensile force is not introduced in the installation, the play of a joint of the tie bar 1 and the like can be absorbed; and a prestress of a relatively high desired value is introduced.
