Additive for controlling heat flow from mineral binder composition, mineral binder composition and method for producing same
The invention relates to an admixture for a mineral binder composition, in particular for concrete, comprising or consisting of: a) at least one kinetic modulator selected from esters of hydroxycarboxylic acids, in particular citric acid esters, tartaric acid esters, lactic acid esters, gluconic acid esters, malate esters, glycolate esters and/or mandelic acid esters, and b) at least one additive selected from among esters of hydroxycarboxylic acids, in particular citric acid esters, tartaric acid esters, lactic acid esters, gluconic acid esters, malate esters, glycolate esters and/or mandelic acid esters; b) optionally an accelerator for cement hydration, and c) optionally water. The admixture of the present invention reduces the maximum heat flow from mineral binder compositions, in particular concrete, without excessively delaying its setting and/or curing.
本发明涉及一种用于矿物粘结剂组合物，尤其是用于混凝土的外加剂，所述外加剂包含以下或由以下组成：a)至少一种动力学调节剂，其选自羟基羧酸的酯，尤其是柠檬酸酯、酒石酸酯、乳酸酯、葡糖酸酯、苹果酸酯、乙醇酸酯和/或扁桃酸酯，b)任选的用于水泥水合的促进剂，和c)任选的水。本发明的外加剂降低了来自矿物粘结剂组合物，尤其是混凝土的最大热流，而不会过度延迟其凝固和/或固化。
