Title: Shrinkage Properties of Self-Compacting Concrete with HighVolumes of Class F Fly Ash
Abstract: Self compacting concrete (SCC) is becoming more popular in the present days due to its ability of passing
through congested reinforcement without the aid of external vibration effort. To possess self-passing ability fresh
concrete should have good cohesiveness. Use of large quantity of fine materials can impart cohesiveness to the SCC.
Fly ash (FA) is one of such fine materials which can be used in SCC. In this study effect of class F fly ash on
different properties of SCC was studied. Ordinary Portland cement (OPC) was replaced with (30-70) % FA in SCC.
Water to binder ratio was maintained 0.325 for all SCC mixes. Slump test, flow ability and filling ability tests were conducted on fresh concrete. Hardened concrete properties such as compressive strength, drying shrinkage, split tensile strength and flexural strength were also studied. SCC mixes developed compressive strength ranging from 26 to 48 MPa at 28 days. Drying shrinkage strain was decreased with increase in FA content
