Abstract (en)
[origin: WO2012084401A1] The invention relates to a hydraulically curable composition, in particular for producing concrete, mortar, screed or render, having improved freeze-thaw resistance, which comprises the constituents cement, additives, organofunctional silicon compounds and optionally aggregates and optionally further constituents and which contains the further constituents fly ash and silica dust, in each case independently, in an amount based on the weight of cement of from 1 to 25% by weight and the organofunctional silicon compounds in an amount of from 0.1 to 5% by weight based on the weight of cement. The invention further relates to a process for producing the composition and also to the use of the combination of constituents for improving the freeze-thaw resistance.
