Abstract:

 The use of self-compacting concrete (SCC) is highly recommended in the places where thin structural members with congested reinforcements are used. Permeation properties such as permeability, absorption, diffusivity etc., need to be studied to quantify the durability characteristics of SCC. This paper presents the results of experimental investigation on permeation properties of different grades of SCC containing high volume fly ash and the test results have been compared with conventionally vibrated concrete (CVC). Experiments were carried out on different grades (30MPa-60MPa) of SCC, designed based on a rational mix design method with high volume fly ash. The results on the permeation properties show that permeability and adsorption characteristics of all grades of SCC are lower than the CVC of same grades. The chloride diffusivity was found to be much dependent on the fly ash content. SCC with more fly ash content shows lesser diffusivity was found to be much dependent on the fly ash content. SCC with more fly ash content shows lesser diffusivity compared to other grades. It can be concluded that all grades of SCC produce better durability characteristics compared to CVC of same grades.
