CONCRETE COMPOSITION HAVING HIGH FLOWABILITY

摘要

A concrete composition which exhibits high flowability, low decrease in flowability with progression of time and lack of segregation over time, is composed of from 350 to 700 Kg of hydraulic cement material per m3 of concrete, up to 185 g of water per m3 of concrete, fine aggregate, coarse aggregate and from 0.05 to 3 parts per 100 parts of hydraulic cement material of certain specific alkenyl ether/maleic anhydride copolymers material.
