摘要： PURPOSE: To minimize the adding quantity of a hydration heat-decreasing agent and prevent cracking. CONSTITUTION: The whole placing area D of mass concrete is divided into the first area of concrete 1 without hydration heat-decreasing agent and the second area of concrete 2 with hydration heat-decreasing agent. The placing area L of the second concrete 2 is divided into n areas 11 , 12 ,..., 1n and the initial value of the addition rate in respective layers of the second concrete 2 is a1 , a2 ,... an . The addition rate of the hydration heat-decreasing agent of respective layers of the second concrete 2 is increased gradually by every Δa from the initial value to the upper limit value Amax to get the addition rate of the hydration heat-decreasing agent of the second concrete 2 at the time when the tensile stress of concrete in respective positions, calculated from a temperature-stress analysis is less than the tensile strength of concrete and the addition volume of the hydration heat-decreasing agent becomes minimum.

摘要： PROBLEM TO BE SOLVED: To efficiently prepare an in-situ concrete pile superior in quality such as strength, without arranging a weld reinforcement part of excessive cast-in-situ concrete on the pile head top end surface of a planned pile, when preparing a pile by placing concrete in a pile hole.
SOLUTION: When the top end of the concrete reaches the lower end of a casing built up on the ground surface side of the pile hole by placing the concrete in the pile hole, while continuing the placing of the concrete, a part mixed with an impurity such as slime on the top end surface of the concrete is removed by a vacuum hose until its top end reaches the top end surface of a planned pile in the casing. Afterwards, the top end of the placed concrete is set in a height coincident with the top end surface of the planned pile, and the quantity of concrete mixed with the impurity such as slime to be removed and treated is reduced, to provide the pile superior in quality.

摘要： PROBLEM TO BE SOLVED: To provide high strength and extra-high strength concrete and high strength and extra-high strength concrete structure which enables explosive fracture suppressing action to be properly secured.
SOLUTION: A latent heat effect development material for decreasing the temperature increase ratio of the high strength and extra-high strength concrete exposed under a high temperature atmosphere with time by the latent heat effect of absorbing heat in the melting and the vaporization by the heating to 450°C is incorporated with the high strength and extra-high strength concrete. As the latent heat effect development material, a high polymer compound having a heat decomposition temperature lower than 450°C is preferably used. An outer shell PCa concrete member constituting a structure such as columns, beams or walls is made from the high strength and extra-high strength concrete. The high strength and extra-high strength concrete structure is formed by placing and filling concrete having strength higher than that of regular concrete in a space formed by the outer shell PCa concrete member and integrating the outer shell PCa concrete member with a surface layer part.

摘要： PURPOSE:To retard a hydration to prevent mass concrete from cracking, by placing an inner layer concrete in which no reducing agent of hydration heat is added and placing an outer layer concrete in which the reducing agent of hydration heat is added. CONSTITUTION:Inner layer concrete 1 without additives is placed in a form 3 and outer layer concrete 2 in which a hydrolyzable tannin is added as a retarding agent, is placed on the concrete 1 immediately thereafter. When concrete 12 is placed in layers, concrete 13 in contact with the form 20 at the periphery, in which a reducing agent of hydration heat is added, has been placed to heap up, and coincrete 12 without additives is placed in the middle. Many layers composed of the concrete 12, 13 are superposed and concrete 14 with the reducing agent of hydration heat is placed as the uppermost layer. The rising speed of the hydration heat and the setting and curing speed of the outer concrete 2 are made slower than those of the inner concrete 1. In this way, the difference of thermal deformation volume between the inner and outer concrete 1, 2 can be absorbed.
