摘要： The invention is concerned with a lightweight aggregate which is inhibited for water absorption by pressure. The aggregate is treated with an aqueous polymer dispersion having a viscosity permitting the dispersion to enter fine pores in a surface layer of the aggregate by absorption, the dispersion so entered in the pores being thickenable by rise of pH and when so thickened having a viscosity of not less than 50 times the viscosity before thickening.

摘要： PURPOSE:To obtain an admixture capable of imparting high strength to a cement composition and excellent in stability by calcining natural kaolin, halloysite or synthetic kaolin and specifying the amorphous part content and the diameter and sp.gr. of all the particles. CONSTITUTION:At least one kind of material among natural kaolin, halloysite and synthetic kaolin is calcined at 630-870 deg.C, and the calcined body is classified to obtain a cement admixture consisting essentially of an amorphous part, with the alumina-to-silica ratio controlled to 1.1-1.3, the diameter of all the particles to 8mum and the average particle diameter to 0.5-2.0mum and having 2.45-2.55 sp.gr. The admixture is added to cement by 5-30wt.% based on the total weight, and a thin aggregate, a water reducing agent and water are added and mixed to obtain a cement composition. The composition develops sufficient strength as in the case when a silica fume is used as the admixture and also develops high strength at an early stage, and the contraction due to drying is reduced.

CONSTITUTION:A sheathing plate 1 consisting of the heat-transmitting materials of stainless steel, aluminum alloy, and the like, and a reinforcing plate 2 consisting of the heat-insulating materials of glass fiber reinforced plastics and the like area arranged. After that, a reinforcing frame 3 consisting of the plastics corrugated-plate and the like of a plurality of flow courses 4 formed in parallel with each other is set. After that, the plates 1, 2, 3 are laminated in the order, and a form A is formed, and at both ends, a male type connecting- section 5A and a female type connecting-section 5B are arranged, or headers are arranged. Then, the form is assembled and concrete is placed, and after that, into the flow courses 4, the heat media of water, air, and the like are fed, and the concrete is kept at a required warm or cool temperature. As a result, reinforcing members are saved, and the concrete can be easily cured with safety and at a proper temperature.

摘要： PROBLEM TO BE SOLVED: To provide a vertical loading testing method for testing a support performance of an existing pile of an existing building, such that a concrete reaction body for obtaining a reaction from the existing building is capable of presenting a sufficient reaction.SOLUTION: A vertical loading testing method includes the steps of: separating an existing pile and a foundation skeleton of an existing building; constructing a concrete reaction body connected to the existing building at an upper side of the existing pile; and measuring a support performance by applying a load to the existing pile through a jack installed in an upper end of the existing pile. When installing the concrete reaction body, an installation area is divided into two or more partial layer areas in a vertical direction. For each partial layer area, a management material age is determined which is the number of days required for achieving a predetermined strength from a date of installation through a curing term. A target date is determined commonly for all the partial layer areas and in accordance with the management material ages of the partial layer areas, the date of installation for each partial layer area is determined by inverse calculation from the target date.
