CONCRETE COMPOSITION AND MAKING METHOD
A concrete composition is obtained by dry mixing cement and an aggregate, adding thereto a water dispersion which is preformed by dispersing a low-substituted hydroxypropyl cellulose having a hydroxypropoxy substitution of 5-16 wt% in the form of fibrous particles having an aspect ratio of 4-7 in water, and mixing the ingredients. Because of reduced drying shrinkage, only slight loss of fluidity, and proper flow, the concrete composition is useful to form concrete buildings having frost damage resistance.
