摘要: A process for modifying the slump of a concrete or mortar by the addition at different times of a water-soluble poly(alkylene oxide) and a .beta.-naphthalene sulphonate-formaldehyde condensate, a plasticizer or superplasticizer which is selected from lignosulphonates, melamine sulphonate formaldehyde condensates, carboxylates and selected styrene-maleic anhydride copolymers. The poly(alkylene oxide) is preferably partially replaced by a (hydroxy)alkyl cellulose. The process is advantageously used in shotcreting.

摘要: The interlayer adhesion and final strength of cementitious compositions which are applied in consecutive layers are improved by the incorporation in the compositions of an admixture which is a combination of a waterproofing agent and a water retention agent. The invention is particularly applicable to sprayed concrete.
