Abstract: A presente invenção se refere a uma formulação de aditivo retardador de pega compreendendo aminas orgânicas, por exemplo, monoetanolamina e dietanolamina, preferencialmente trietanolamina; um álcool, sendo preferencialmente o composto de cadeia C3, glicerina, a qual pode ser destilada ou derivada do biodíeseí e um glicol, podendo ser acrescido à formulação um glicol como monoetilenoglicol, dietilenoglicol ou trietilenoglicol. Tal formulação, quando aplicada sobre a massa de cimento, irá proporcionar um concreto com características melhoradas de retenção de pega e resistência mecânica.

Abstract: 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.

Abstract: This invention relates to a process for preparing permeable-aerated mortar with a high early strength and water-nonseparating properties, which is appropriately filled and applied to various kinds of cavities and gaps where water exists or flows slightly. This is accomplished by a process, wherein high early strength water-nonseparating mortar materials comprising an ultra-rapid hardening cement, a fine aggregate and a thickener are mixed with water, and foams prepared by a foaming agent and water are subsequently added thereto.
