Abstract

SE DESCRIBEN ACELERADORES DE FRAGUADO Y ENDURECIMIENTO PARA CEMENTO Y MEZCLAS QUE LOS CONTIENEN, QUE NO LLEVAN METALES ALCALINOS NI CLORUROS Y NO TIENEN PROPIEDADES FUERTEMENTE BASICAS. LOS ACELERADORES DE FRAGUADO CONTIENEN COMO COMPONENTES 1. SULFATO DE CALCIO DIHIDRATADO, 2. HIDROXIDO DE ALUMINIO AMORFO Y/O SALES BASICAS DE ALUMINIO. MEZCLANDO SULFATO DE CALCI, HIDROXIDO DE ALUMINIO AMORFO Y/O SALES BASICAS DE ALUMINIO SE REDUCE CLARAMENTE EL TIEMPO DE FRAGUADO Y SE ALCANZA RAPIDAMENTE UNA ELEVADA RESISTENCIA A LA PRESION SI LO COMPARAMOS UTILIZANDO SOLO EL SEGUNDO COMPONENTE. UTILIZANDO SULFATO DE CALCIO DIHIDRATADO SE PUEDEN OBTENER ACELERADORES ESTABLES, LIQUIDOS Y EN FORMA DE DISPERSION.
