Abstract
In this present study the durability characteristics of Steel fiber reinforced Self compacting concrete (SFRSCC) is determined for M30 and M40 grade concrete mixes. Along with durability strength and sorptivity is carried out and comparison is made with Plane self-compacting concrete (SCC) by chemical resistances, Initial Surface Absorption Test (ISAT).
 In the present study, the rational mix design procedure for self-compacting concrete is used. SCC mixes contains large quantity of powder (material whose parcel size is 0.125 mm) to maintain the plastic yield of the properties of fresh concrete as per the general guidelines for design of SCC mixes given in the EFNARC (2005). The present project consists of two phases. In the first phase, SCC mixes for different grades are developed without steel fibers and with steel fibers. The mechanical properties like compressive strength of the different grades were studied. In the second phase, based on the experimental results, durability properties were studied with the using of specimens of size 100 mm × 100 mm × 100 mm. Durability studies like Acid attack factors, Acid-Durability factors, Sulphate attack factors, Sorptivity are studied for the Plain SCC and steel Fiber Reinforced SCC and a comparison is made.
Highlights
Self-compacting concrete (SCC) is the one in which the compaction of concrete is done under its own weight
The compressive strength is determined at the curing age of 7 days and 28 days with and without using fibers.The present study it was divided into two phases in phase I workability and compressive strength is determined, in phase II Durability and sportivity is determined with and without using steel fibers
Fiber reinforced self-compacting concrete is made with steel fiber to improve its strength properties
Summary
Self-compacting concrete (SCC) is the one in which the compaction of concrete is done under its own weight. The strength of the concrete is main and important concept in concrete studies, this strength is depends upon various parameters like material properties and mix proportion the strength will increases or decreases depending upon these two parameters. The main concept of using fibers in concrete is to increase the strength and at the same time we can decrease the cracking effect . There are different types of fibers are there which helps to decrease the cracking effect and to increase the strength like steel fibers, polypropylene fibers, polyester fibers, carbon fibers, micro synthetic fibers, natural fibers and cellulose fibers. In the present study I was selected steel fibers in M30, M40 grade concrete to study the comparison of strength, durability and sportivity values. The compressive strength is determined at the curing age of 7 days and 28 days with and without using fibers.The present study it was divided into two phases in phase I workability and compressive strength is determined, in phase II Durability and sportivity is determined with and without using steel fibers
