Abstract

UN POLISACARIDO MICROBIANO QUE TIENE LAS PROPIEDADES CARACTERISTICAS DEL S-657 Y MEJORA EFECTIVAMENTE LAS PROPIEDADES REOLOGICAS DE UNA VARIEDAD DE SISTEMAS CEMENTOSOS. LA ADICION DEL S-657 A TALES SISTEMAS CEMENTOSOS, COMO EL CEMENTO PORTLAND, PASTAS DE CEMENTO AUTOENRASABLES, MEZCLAS PASTOSAS DE CEMENTOS DE POZOS DE PETROLEO DE AGUA DULCE O SALADA, CEMENTOS MICROFINOS, ORIGINA MEJORAS SUSTANCIALES EN TALES PROPIEDADES COMO PERDIDA DE AGUA, RESISTENCIA AL FLUJO, CONTROL DE PERDIDA DE FLUIDO Y SIMILARES. ADEMAS, EL S-657 TIENE VARIAS VENTAJAS, INCLUYENDO CONTROL MEJORADO DE AGUA LIBRE Y DE SEDIMENTACION, PERDIDAS REDUCIDAS DE MATERIALES FINOS DURANTE SU COLOCACION BAJO EL AGUA, ESTABILIDAD MEJORADA DE LOS SISTEMAS DE CEMENTOS MUY DILUIDOS Y MICROFINOS, FLUJO MEJORADO Y PROCESAMIENTO DE PASTAS ULTRAPROCESABLES Y AUTOSELLANTES, MEJOR DESARROLLO DEL COLOR EN CEMENTO COLOREADOS Y ATRAPAMIENTO ESTABILIZADO DE BURBUJAS EN SISTEMAS CELULARES O ESPUMOSOS CEMENTOSOS. EN SISTEMAS CEMENTOSOS PULVERIZABLES, EL S-657 REDUCE EL REBOTE Y EL COMBAMIENTO.
