EVALUATION OF THE SEGREGATION RESISTANCE OF FRESH SELF-COMPACTING CONCRETE USING DIFFERENT TEST METHODS
Test methods,both the common ones currently used in self-compacting concrete(SCC)and relatively new ones that are being developed to assess the segregation of SCC,are introduced in this paper.The paper concentrates on the relevance of the method to evaluate the resistance of segregation tests and the focus is on the measurement of the segregation of fresh SCC.This paper also describes a new test settlement column segregation for testing fresh segregation of SCC.The development of the settlement column segregation test and the parameters in terms of test result to describe acceptable and non-acceptable SCC,and possible applications of the test method are addressed.The Belgium settlement column test,having small dimensions and which the concrete is stroked with a bar unseated of jolting,was also used.Other test to assess the segregation of fresh SCC,wet sieving segregation test manual was used.The repeatability and the reproducibility of the settlement column test segregation are also investigated.
