Abstract
This invention provides a hydraulic composition which contains a cementitious material in powder form, .beta.-1,3-glucan, and a superplasticizer. The composition makes it possible to prepare concrete with high resistance to segregation, high fluidity, and excellent filling ability. Because of this, vibration of the concrete is not necessary during casting; it can simply be poured.
