A cement admixture which is reduced in the burden to be imposed on the environment, is effective in diminishing hexavalent chromium, is reduced in slump loss and heat of hydration, is less apt to be neutralized, and can be reduced in self-shrinkage. The cement admixture comprises an air-cooled blast furnace slag powder which consists mainly of a melilite and has a CO2 absorption of 2% or higher and an ignition loss of 5% or lower. In the powder, the content of sulfur not in the form of sulfuric acid is 0.5% or higher and/or the concentration of non-sulfuric-acid-form sulfur which dissolves away is 100 mg/L or higher. Preferably, the powder has a degree of vitrification of 30% or lower, a melilite lattice constant, a, of 7.73 to 7.82, and/or a Blaine specific surface area of 4,000 cm2/g or larger.
42 CONTROLLED REACTIVITY QUICKLIME AND METHOD FOR PRODUCING AERATED AUTOCLAVED CONCRETE EP97933301 1997-07-16 EP0912456A4 2007-04-25 HUEGE FRED R; INGRAM KEVIN D; PENDLETON GREGORY B; WALTER DIETHAM
A method for manufacturing an aerated autoclaved concrete material. A quick-stiffening mixture is prepared by combining a silica containing material, quicklime, a rising agent, gypsum, cement and water. The mixture is deposited into a mold and is allowed to form a stiffened body. The stiffened body is removed from the mold and placed in an autoclave station in which it is steam cured at elevated temperature and pressure. The quicklime which is used to form the quick-stiffening mixture is modified with a chemical modifier to provide a desired degree of chemical reactivity in the quick-stiffening mixture.

A cement admixture and a cement composition having a carbonation suppressing effect and a heat-of-hydration suppressing effect are provided. A cement admixture containing one or more non-hydraulic compounds selected from the group consisting of γ-2CaO·SiO2, α-CaO·SiO2 and calcium magnesium silicate, a cement composition containing said admixture, and a carbonation suppressing method by use of said cement admixture or cement composition. According to the present invention, a remarkable carbonation suppressing effect can be obtained particularly when used in portland blast-furnace slag cement. This leads to an effective use of steelmaking slag and the like, and the load of clinker can be reduced, so that a cement composition of a low environmental load type can be attained. Further, this is suitable for cements in conformity with the EN standards, which are used in civil engineering and building industries.

A mixture for concrete mortar is provided to increase strength of concrete mortar, have an energy reduction effect, and produce concrete mortar having thermal insulation and heat storage performances in a low cost. A mixture for concrete mortar having thermal insulation and thermal storage functions and strength-enhancing functions is obtained by adding 5wt% of an AE water-reducing agent and a very small amount of a cellulose-based thickener to 50wt% of water and 45wt% of phase change material capsules. The mixture is configured to prevent cracks and improve strength even without reducing flowability, absorb heat of hydration by the phase change material, and absorb a heat load from the outside and emit the heat slowly.

An organic acid, reactive silica fine powder and/or gypsum anhydrite can be further blended. At this time, the blending ratio of, for example, 5-40 pts.wt. thiocyanate and/or thiosulfate, 5-30 pts.wt. organic acid, 30-90 pts.wt. dextrin or 2-25 pts.wt. thiocyanate and/or thiosulfate, 0.5-10 pts.wt. organic acid, 65-95 pts.wt. reactive silica fine powder and/or anhydrous gypsum or 0.5-10 pts.wt. thiocyanate and/or thiosulfate, 0.5-5 pts.wt. organic acid, 5-40 pts.wt. dextrin and 40-90 pts.wt. reactive silica fine powder and/or anhydrous gypsum is preferable.
55 Shrinkage reducing agent for cement and hydration heat reducing agent for cement JP22714692 1992-08-26 JPH0672749A 1994-03-15 NAKANO SHOICHI; KOYAMA NORIYUKI
PURPOSE:To provide a shrinkage reducing agent for cement and a heat-of- hydration reducing agent for cement excellent in handling property and addition effect. CONSTITUTION:The shrinkage reducing agent for cement and the heat-of- hydration reducing agent are made of 1,6-hexanediol. Since 1,6-Hexanediol is solid at ordinary temp., it can be powdered and mixed with cement or the like to be used, or can be previously dissolved in water owing to its excellent solubility in water, handling property is excellent. Extremely excellent shrinkage reducing effect and heat-of-hydration reducing effect are attained only by adding relatively small quantity of 1,6-hexanediol.
