摘要： The present invention relates to a method for increasing the workability of a binder composition comprising calcined clay, limestone, and Portland cement. Said method comprises a step of adding an admixture comprising at least one PCE and at least one additive selected from the group consisting of sugar acids, sugars, sugar alcohols, and hydroxycarboxylic acids. The invention also relates to an admixture to be used in said method and hardenable compositions, especially concrete and mortar, obtainable by said method.

摘要： The present invention discloses a combination of set retarders and regulators for the hydration reaction of cementitious binders comprising clinkers based on Ye'elimite. The set retarders are calcium complexing agents, preferably selected from the group consisting of sugar acids, sugars, sugar alcohols, hydroxycarboxylic acids, phosphates, phosphonates, borates and amines. The regulator is of the general formula (I) where M is H, NhU or chosen from a monovalent or divalent metal of the groups la lla, IlIa, lb, IIb, IVb, Vlb, Vllb or Vlllb of the periodic table of elements, and, where M is a divalent metal, a second equivalent of R-SO 3 is present, and where, preferably, M is chosen from the group consisting of H, NH 4 , Li, Na, K, MgX, CaX, or NiX with X = RSO 3 , and where R is chosen from H, NH 2 , OH or from a hydrocarbon chain with 1-18 C atoms which may be substituted by N and/or O and/or which may be linear or branched and/or which may contain one or more unsaturated bonds and/or cycloaliphatic and/or aromatic moieties. The combination of set retarders and regulators of the present invention is useful to control the hydration reaction at early age of said cementitious binders comprising clinkers based on Ye'elimite. More particularly, it is possible by a combination of set retarders and regulators of the present invention to prolong the open time and at the same time accelerate the setting of a cementitious mixture comprising cementitious binders comprising clinkers based on Ye'elimite. The present invention also discloses uses of a combination of set retarders and regulators of the present invention as well as methods for the control of the hydration reaction at early age of cementitious binders comprising clinkers based on Ye'elimite.

摘要： Described is a shotcrete accelerator which is a solid comprising at least one of jurbanite and hydronium alunite or an aqueous suspension or slurry of the solid, and a method of producing the shotcrete accelerator as a solid. The solid shotcrete accelerator is redispersible in water yielding stable aqueous dispersions or slurries. Extended shelf life of the solids and aqueous dispersions and reduced transport costs are the main advantages compared to existing technologies.

摘要： The present invention relates to an admixture for mineral binder compositions, especially for concrete, said admixture comprising or consisting of a) at least one kinetic regulator selected from esters of hydroxy carboxylic acid, especially citric acid esters, tartaric acid esters, lactic acid esters, gluconic acid esters, malic acid esters, glycolic acid esters, and/or mandelic acid esters, b) optionally an accelerator for the hydration of cement, and c) optionally water. Admixtures of the present invention reduce the maximum heat flow from mineral binder composition, especially concrete, without unduly retarding setting and/or curing thereof.
