Abstract

La presente invención proporciona una composición de mezcla seca de un éter de celulosa de baja viscosidad (50 a 750 mPa•s a 1 % en peso de sólidos, a 20 C, y una velocidad de cizallamiento de 514 s-1, usando un reómetro rotacional de tensión controlada (por ejemplo, ARES-G2(tm), TA Instruments), un agregado graduado y un cemento hidráulico, o una composición de cemento húmedo granular del cemento, agregado graduado y una mezcla de estos, que incluyen el éter de celulosa. La composición de cemento hidráulico granular húmedo se comporta como las composiciones de asfalto y tiene un asentamiento casi cero o cero, una alta lubricidad y de 5 % en peso a menos de 13 % en peso de agua, o, preferentemente de más de 5 a 10.5 % en peso, basado en el peso total de la composición de cemento húmedo granular. El éter de celulosa de baja viscosidad permite la lubricidad sin afectar la compactación y sin causar arrastre de aire.
