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 a little drop of fluidity, and proper flow, the concrete composition is useful to form concrete buildings having frost damage resistance.
