  • Hydraulic binder with enhanced aging properties
    Patent number: 7074269
    Abstract: Hydraulic binders, such as cements, mortars with enhanced aging properties, are described. More particularly, hydraulic binders based on mineral silicates are described having greater aging strength, a method for making said binders and their uses and articles obtained from same. An organic compound comprising two hydrophilic functions and a hydrophobic chain such as adipic acid are added to the hydraulic binder to slow down the water uptake rate of said binder.

  • Compositions based on phenolic derivatives and their use as mineral binder additives
    Publication number: 20030162866
    Abstract: The invention concerns a composition based on phenolic derivatives and their use as mineral binder additives, enabling to obtain mineral matrices, preferably of mortars and concrete mixtures, with improved properties. The invention also concerns a composition for binders, in the form of a powder or an aqueous suspension, comprising at least a phenolic derivative and at least a polymer. The invention further concerns methods for preparing those various compositions, and their uses in particular for making mortars and concrete mixtures.

  • Self-leveling fluid mortar including calcium sulfate and lime
    Patent number: 5910215
    Abstract: The invention relates to a self-levelling fluid mortar including calcium sulphate, granulates, lime, water and either a silica and a compound containing alumina or a pozzuolana, and to a screed obtained from said fluid mortar. It also relates to the combined use of lime and either of a silica and of a compound containing alumina or a pozzuolana to increase the mechanical strength and reduce the water sensitivity of a screed.
