| PROBLEM TO BE SOLVED: To prolong a hardening time and to reduce metal corrosion, by mixing a cement with a phosphonocarboxylic acid or its salt. SOLUTION: This cement composition contains particles capable of reacting in the presence of an aqueous liquid medium and aggregating to form a solid mass (lump) and provides effective hardening retardation, corrosion prevention of iron and steel and improvement in dispersion, deflocculation, etc., by adding a phosphonocarboxylic acid or its salt in an amount to modify the formation of the mass to the cement composition. Sodium or potassium phosphonocarboxylate is preferable as the retarder. The most preferable phosphonosuccinic acid is a phosphonated telomer of active olefin of the formula H[CHRCHR] n-PO 3M 2 (one or more of Rs are COOH and the others are each H, COOH, OH, an alkyl, etc.; 1<(n)<200; M is H or a cation). The retarder in an amount of 0.01-5 wt.% based on the total solid content weight is made present in a cement. COPYRIGHT: (C)1999,JPO | ||||||

| (57)【要約】 硬化したセメントマトリックスは高圧の稠密相ないし超臨界ＣＯ 2にさらされ、このＣＯ 2はマトリックス内の通路を通ってマトリックス内に入り、セメントの自然のアルカリ度を中性化して、アルカリ不耐性の材料がセメント内に含ませることができる。 ＣＯ 2はセメント内の水酸化カルシウムを炭酸カルシウムと水に変換し、また高圧の稠密相あるいは超臨界ＣＯ 2は、視覚可能な細孔あるいは毛細管が殆どなく、丸い、緊密に詰め込まれ隣接した結晶を形成し、硬化したセメントの均質性および強度並びにその例えば被覆されない補強ガラス繊維との結合が増大する。 超臨界ＣＯ 2は、微粉化された金属を含む、他の有機あるいは無機の材料を、セメントマトリックスの内部に溶液あるいは懸濁液で運搬してその化学的および物理的な特性を変えるために使用することができる。 | ||||||

| PURPOSE:To provide a water pollution preventing agent for absorbing alkali calcium eluted into water because of hydraulic materials such as cement, lime, a solidifying material containing cement or lime, concrete and mortar used at the time of solidifying mud or constructing an artificial pond or a waterway. CONSTITUTION:A water quality turbidity preventing agent contains calcium oxide, calcium sulfate, aluminum oxide and silicon dioxide cured materials, and is prepared by mixing one or more of slaked lime, quick lime, gypsum and volcanic ash with coal ash or 1 used coal waste gas treatment agent and hydrated curing, and then treating by means of smoke containing sulfur oxide and nitrogen oxide. The water pollution preventing agent is prepared by utilizing a used smoke treatment agent of lime family, and the elusion of alkali calcium and the rise of pH can be reduced and controlled easily and effectively by the agent. As the pollution preventing agent itself is cured in water to form a solidified body, neither outflow from the water nor scattering in the water is generated, and secondary pollution is also prevented. | ||||||

| The present invention provides methods and compounds for the direct sequestration of chloride ions without requiring the addition of a source of anion such as nitrite or nitrate. A direct sequestration additive is introduced to fresh concrete or hardened concrete where the additive reacts with incoming chloride ions to form a low solubility, chloride-containing compound which captures or sequesters chloride ions. In a preferred embodiment, the chloride-containing compound comprises 3CaO•Fe(2-x )AlxO3•CaCl2•nH2O , where x ranges from about (0) to (1.4), and n ranges from about (8) to (24). The chloride ions may be provided in the form of deicing salt or sea water. Because chloride-containing compounds such as 3CaO•Fe(2-x)AlxO3•CaCl2•nH2O are formed directly without requiring the addition of a source of anion (e.g. nitrite or nitrate), the process is referred to as 'direct sequestration'. | ||||||

| In some embodiments, alternate sources of aluminum or calcium are provided in various ways including the desired compounds. The further object of the present invention contemplate in situ creation of the compound in interest in fresh concrete and as a slurry which can be employed in remediation of existing concrete structures. A method of resisting corrosion in concrete containing metal elements is provided. It includes introducing into fresh concrete, containing metal elements, at least one compound capable of sequestering chloride ions. The method may also involve employing a compound which is capable of establishing a corrosion resistant oxide layer on the metal reinforcing elements. The invention also includes certain compounds which may be employed in the method as well as concrete structures containing the compounds. In another embodiment of the invention, concrete structures may be rehabilitated by providing an overlay containing a compound of the type which will contribute to corrosion resistance either through chloride ion sequestering or creating barriers around metal structural elements with the overlay being provided in situ or as a preformed member and with possible use of a slurry in combination with an overlay segment. In another embodiment, a source of alumina is combined in solution with Ca(NO2)2 and/or NaNO2 with the resultant solution being introduced into the pores of a concrete structure, preferably under pressure to cause them to react with each other and with Ca(OH)2 contained within the concrete to produce the desired corrosion inhibiting compound. | ||||||

Das beschriebene Verfahren betrifft die Behandlung von Trinkwasser-Rohrleitungen, deren Innenflächen zumindest teilweise aus frischem Zementmörtel bestehen, und hat zum Gegenstand, daß die Rohrleitung (1) mit einer Gasmischung beaufschlagt wird, die Kohlendioxid in einer Konzentration oberhalb der normalen atmosphärischen Kohlendioxid-Konzentration enthält. Diese Konzentration liegt im Bereich von 5 - 95 Vol.%. Die Dauer der Behandlung beträgt weniger als 24 Stunden und vorzugsweise 1 - 6 Stunden. Durch das neue Verfahren werden die Rohrleitungen innerhalb kürzester Zeit gebrauchsfertig, was bei der Sanierung der Rohrleitungen in situ durch eine nachträglich aufgetragene Zementmörtel-Auskleidung mit dem besonderen Vorteil verbunden ist, daß die bisher erforderliche, mit viel Kosten und Zeitaufwand verbundene Spülung der Rohrleitung entfallen kann. Vorzugsweise wird dabei die Beaufschlagung der Rohrleitung Innerhalb von weniger als 24 Stunden und vorzugsweise innerhalb von 5 - 10 Stunden nach dem Auftrag der Auskleidung begonnen. |
