Study on strength properties of SCC with partial replacement of granite sludge Latha1, Rekha B V2 1HOD, Department of Civil Engineering, R R Polytechnic, Karnataka, India 2Lecturer, Department of Civil Engineering, R R Polytechnic, Karnataka, India ---------------------------------------------------------------------***--------------------------------------------------------------------1.1 Objective of persent investigtion: Abstract –
SCC is highly engineered concrete with much higher fluidity without segregation & is capable of filling every corner of the formwork under its self weight. Thus SCC eliminates the need of vibration either external or internal for the compaction of concrete eithout compromising its engineered properties. The assurance of nature is a fundamental aspect, which is specifically associated with the survival of civilization. Parameter like ecological awareness, defence of natural resources, maintainable improvement assume a fundamental part in present day necessity for development. Remembering this in this review the fresh & harden properties of SCC utilizing granite waste as a partial replacement for cement were assessed. Cementatious material in the mix was replaced with granite waste at 10%, 14%, 18% & 20% by weight of cement. The result shows that the use of granite waste will build the quality of SCC when compared with the normal SCC but it should not exceed 10% of granite waste..
1.2 Scope of study: In present investigation, to accomplishes the SCC by replacing the cement with granite sludge. Trail 1: Utilize 100% cement & 0% granite sludge Trail 2: Utilize 90% cement & 10% grante sludge Trail 3: Utilize 80% cement & 20% granite sludge Trail 4: Utilize 86% cement & 14% granite sludge Trail 5 : Utilize 82% cement & 18% granite sludge
Key Words: SCC, Mineral admixture, Granite sludge
2. Materials used & tests conducted on it:
1.INTRODUCTION
CEMENT: Table -1: Tests & Results of cement
Concrete is the most basic element of any kind of construction work. No matter what type of building structure it is, the concrete used study & well compacted.
Tests conducted & its results
The main reason for comoacting the concrete is to ensure maximum density & to ensure concrete used is full in contact with steel & formwork. SCC is defined as “ Concrete that is able to flow and consolidate under its own weight , completely fill the formwork even in the presence of dense reinforcement , while maintaining homogeneity without the need of additional compaction ”. SCC should contain :
Lower coarse aggregate content
Higher amount of sand & cementaious material
Lower water cement ratio
Higher super plasticizers ratio
