摘要： PROBLEM TO BE SOLVED: To obtain the subject additive capable of improving stability of the fluidity of a hydraulic composition with time, providing a desired fluidity with a small amount of water and capable of realizing the high strength and a low drying shrinkage of a hardened material by using an admixture having masking effects or actions as a dispersing agent. SOLUTION: This additive for a hydraulic composition containing rejected soil in order to improve the fluidity of a hydraulic composition containing the rejected soil. The composition contains (A) an admixture having masking effects [e.g. a hydroxycarboxylic acid (salt), a phosphonic acid derivative (salt) or saccharides (derivatives)] or (B) an admixture having actions as a dispersing agent e.g. a (high-performance) [air-entraining(AE)] water reducing agent, concretely ligninsufonic acid (salt) or a melaminesulfonic acid formalin condensate}. For example, the additive is used in an amount of the admixture which is the component A or B of 0.01-5.0 wt.% based on the amount of the hydraulic solidifying material.

摘要： PROBLEM TO BE SOLVED: To make it possible to easily, economically and effectively utilize soil generated in construction and difficult to reuse, without giving an adverse influence on environment by mixing a weak soil with a powdery water-soluble carboxylated polymer to give a granular material and adding a hydraulic material and water to the granular material to form a fluid material. SOLUTION: A weak soil having a cone index of at most 2, among soils generated in construction, is mixed under stirring with about 0.1% particulate water-soluble carboxylated polymer containing 1-80mol%, preferably 5-60mol%, carboxylated monomer for granulation, giving a spherical granular material having a diameter of at most 20mm. This granular material is mixed with a hydraulic material comprising, e.g. normal portland cement, blast furnace cement, jet cement or powdery quick lime, and water, and if necessary, a thickening agent comprising, e.g. carboxymethylcellulose, and a cellular material comprising, e.g. a protein derivative to form a fluid material.

摘要： PROBLEM TO BE SOLVED: To almost completely remove volatile org. chlorine compds. included in a soil and to detoxify a soil by adding and mixing a material which can react with the volatile org. chlorine compds. to produce Friedel salts in the soil containing volatile org. chlorine compds. SOLUTION: In a soil containing volatile org. chlorine compds. (VOCs) which are used in a large amt. in electronic industry, etc., a material which can react with the volatile org. chlorine compds. to produce Friedel salts is added and mixed to modify VOCs in a soil and detoxify and stabilize VOCs. Namely, by adding calcium oxide and a compd. containing aluminum or a calcium aluminate compd. to a soil, Friedel salts are produced in the soil containing VOCs. As for the compd. containing aluminum, At(OH)3 , Al2 O3 , etc., can be used, and as for the calcium aluminate compd., 3CaO.Al2 O3 , etc., can be used.

摘要： PURPOSE:To prevent harmful settlement from happening to a structure by laying, through a sand layer, bags incorporating heating wires right under points where underground beams cross with one another at a right angle, and by making the bags filled, when uneven settlement happened, with cold-setting material which liquefies by heating. CONSTITUTION:After excavating the ground up to a depth about one meter below the lower end of an underground beams (a), bags 3 incorporating heating wires 7 are laid horizontal right under points where the beams (a) cross with one another at a right angle. Then injection pipes 2 are connected to the bags 3 and, at the same time, cocks are provided thereto so that materials to be injected can be supplied from an injection port 6 to optional bags. Sands 5 are then laid even over the bags 3 up to a height reaching the lower end of the beams (a) and after this, construction of the beams (a) and a building (b) starts. In case of uneven settlement, a thermoplastic material such as paraffin, synthetic resin or the like is liquefied by heating and is injected into the bags 3 for correction of uneveness. Thereby a foundation can be constructed directly on soft soil at extremely low cost.

摘要： PURPOSE:To prevent winding of plastic around a casing and the occurence of rebound, by a method wherein a plastic layer is fused by a jet flame from a burner attached to the forward end of the casing. CONSTITUTION:With the forward end of a casing 2 approached to a plastic layer A, plastic is fused by a jet flame (h) from a burner 3, and a fused substance, such as fused plastic, and combustion ash are discharged through an outlet hole 23 with a pressure generated in a combustion chamber 22. After the forward end of the casing 2 is penerated through the plastic layer A to an ordinary soil layer, water is fed in a combustion chamber 22, and excavation is executed by means of tips 21 attached to the forward end of the casing 2. After a boring work is completed, a cast-in-place pile is built in the hole, and the plastic layer is fused by a burner. This enables plastic to be prevented from winding around the plastic casing and permits prevention of the occurrence of rebound.
