Study on durability characteristics of self-compacting concrete with fly ash

Abstract EN

This paper investigates the study of workability and durability characteristics of Self-Compacting Concrete (SCC) with Viscosity Modifying Admixture (VMA), and containing Class F fly ash.

The mix design for SCC was arrived as per the Guidelines of European Federation of National Associations Representing for Concrete (EFNARC).

In this investigation, SCC was made by usual ingredients such as cement, fine aggregate, coarse aggregate, water and mineral admixture fly ash at various replacement levels (10 %, 20 %, 30 %, 40 % and 50 %).

The super plasticizer used was Glenium B233 and the viscosity modifying agent used was Glenium Stream 2.

The experiments are carried out by adopting a water-powder ratio of 0.45.

Workability of the fresh concrete is determined by using tests such as : slump flow, T50, V-funnel, L-Box and U-box tests.

The durability of concrete is tested by acid resistance, sulphate attack and saturated water absorption at the age of 28, 56 and 90 days.
