摘要： PURPOSE: To secure an initial strength while keeping a characteristic of a low pyrogeneous admixture by subjecting a fluorinated apatite and a steel-making dephosphorized slag containing β-C2 S to a heat treatment to reduce a free lime component and compounding a blast furnace granulated slag and gypsum to the resultant dephosphorized slag. CONSTITUTION: The fluorinated apatite and the dephosphorized slag are subjected to the heat treatment at 400-900 deg.C to reduce the free lime component, and a blast furnace granulated slag of the amt. of 0.8-1.2 times the mixture of the apatite and the slag is mixed to this mixture and gypsum of the amt. of 2-10wt.% based on the dephosphorized slag is compound. Up to 30-80wt.%, Portland cement is substituted for the material above in accordance with the purpose. When the dephosphorized slag is heat treated at 400-900 deg.C for 1-2hr, a Ca5 F(PO4 )3 -β-C2 S-CaO based composite solid solution is formed, and the free lime component is surely reduced to

摘要： PROBLEM TO BE SOLVED: To prove means for effectively preventing salt damage to degrade the strength of a concrete structure by the expansion of the iron members in the structure by rust. SOLUTION: The finding that the chloride ions in the concrete structure are the cause for the formation of the rust of the iron members and that the immobilizability of the chloride ions possessed by 3CaO.Al2 O3 (C3 A) is unexpectedly improved by the addition of BaSO4 is obtd. The salt damage is, therefore, effectively prevented by producing the concrete structure contg. a reinforcing material consisting of metallic material and formed by mixing the BaSO4 with cement.

摘要： PURPOSE:To prevent the corrosion of the reinforcing bars in concrete, to improve the durability of a concrete structure in salt component environment and to enable the safe use of sea sand, sea pebbles, etc., by proposing the chemical admixture for suppressing the activity of chlorine ions in hydration reaction of cement. CONSTITUTION:A desired rust inhibitive effect is obtd. by selecting glycine (a kind of amino acids), barium sulfate and strontium nitrate as the materials having the effect of suppressing the activity of the chlorine ions, kneading these materials in such a manner that the materials can be added alone or in combination to the cement at 3 to 10wt.% respectively based on the C3A in the cement, and using the mixture by previously mixing the mixture in water. The rate of suppressing the conversion of monosulfate to an AFm phase is measured and ascertained for the purpose of deciding the effect. The use of the sea sand and sea pebble, which is often worried heretofore, is sufficiently made possible by application of this invention. Further, the salt injury resistance and durability of the concrete structure in the severe salt component environment are improved.

摘要： PURPOSE:To obtain the title product stabilized for a long period of time by bringing ozone-contg. water into contact with the reactive silica component in a base-silica-reactive ceramic product to prevent base-silica reaction. CONSTITUTION:Ozone is brought into contact, in the presence of water, with a water-absorptive ceramic product containing silicic acid and/or silicate component(s) reactive with basic component(s) to modify the reactive site of the reactive silica component, thus obtaining the objective ceramic product prevented from base-silica reaction. The present method can effectively be applied to ceramic products advanced in base-silica reaction; that is, a base-silica reaction product developed on the surface of a ceramic product containing silicic acid and/or silicate component(s) reactive with basic component(s) is removed, and ozone-contg. water is penetrated into the part(s) where said reaction product was developed.

摘要： PURPOSE:To maintain stability, storage property and low exothermic property without deterioration of strength in a shape of a normally used admixture and to improve acid resistance by regulating a mol. ratio of a specified component in a starting material and adding silica thereto to vitrify the result. CONSTITUTION:Limemilk is applied to an inside surface of a baked graphite crucible, and after air-drying the limemilk, the crucible is heated to 500-600 deg.C to apply a lining of lime, and calcium oxide, bauxite, iron ore and silica rock being starting materials are compounded so that the molar ratio of CaO:Al2O3: Fe2O3 is (4+alpha):1:1 (alpha is o =1250 deg.C (>=1450 deg.C) in a kryptol furnace and the mixture is stirred with a graphite rod to confirm complete melting at the time point of fusing and falling of the charged matter, and allowed to flow in a water bath to quench it. This quenched lump is pulverized with a pulverizer to obtain a fused matter having a composition contg. G-C4AF and betaC2S, and blast furnace granulated slag powder or fly ash is mixed with this pulverized powder by the same amount as that of the pulverized powder.

摘要： PURPOSE:To obtain a concrete admixture with the carbonation suppressed due to the low exothermic property when mixed with cement and capable of forming a cement concrete increased in long-term strength. CONSTITUTION:This concrete admixture is obtained by heat-treating a steelmaking dephosphorized slag contg. fluorapatite and beta-C2S at 400-900 deg.C to reduce the free lime content and mixing the slag with a blast-furnace water- crashed granulated slag in 1:0.8 to 1.2 ratio. Consequently, the dephosphorized slag and blast-furnace granulated slag abundantly produced in the steelmaking industry are effectively utilized.

摘要： PURPOSE:To effectively utilize converter slag which is generated in a large amt. in iron and steel making industry and the effective utilization for which is not yet established. CONSTITUTION:The converter slag is slowly cooled by spending 1 to 3 hours between 400 deg.C and 900 deg.C in the process of subjecting the slag to a heating treatment for 15 to 180 minutes or cooling the slag from a molten state, by which the free lime content (measured by a Frank method) contained in the converter slag to , SO4 as a salt injury resistance effect. Further, the long-term compressive strength is improved by the effect of beta-C2S incorporated into the converter slag and simultaneously, the converter slag is helpful as the admixture of a low exothermic type and eventually, the converter slag is effectively utilized as the blank material to improve the durability of the concrete.
