Study on Properties of Low Heat Supper Flowable Nonsegregating Under-water Concrete

Abstract

This paper describes the test results about the properties of Low Heat Supper Flowable Nonsegregating Under-water Concrete by using ternary cement contains cement, G. B. F. S snd Flyash. Test results are summerized as follows; 1) Performance of the concrte, like flowability, setting, strength, adiabatic temperature rising are influenced by property and proportion of cementitious materials and agent. 2) Flowability was closely related to the cellulose deviature absorption phenomenon on cementitious materials and fine aggregate. We prporsed new mixing method of Nonsegregating Underwater concrete which could improve the flowability and stability of concrete.
