retardadores de superfície de concreto com base em éster |
摘要 |
Compositions and methods of the invention for retarding the surface of a concrete or other hydratable cementitious composition involve the use of at least one alkyl-ester-of-hydroxycarboxy compound contained in the form of particles or as a discontinuous phase distributed within a continuous non-aqueous carrier phase that is spray-applicable in liquid form. The set retarder helps to achieve lower pH and to avoid irritating fogs during spray application of the surface retarder when compared to prior art acid-containing surface retarders. |
