Study on Mechanical and Durability Properties of Self-Compacting with Marble Powder

Abstract

Self-compacting concrete (SCC) enhance the qualities and working conditions and it eliminates
compaction. Generally, SCC has higher powder content and it is necessary to replace some of the
cement material to achieve economical and durable concrete. The results show the strength of SCC
with marble powder for constant filling ability, replacement of cement with fly ash requires an
increase in water/powder ratio and a reduction in superplasticizer dosage. This research paper
deals with the different testing methods on fresh concrete to test high-flowability, resistance against
segregation, and passing ability self- compacting concrete for a grade of M60 concrete like Slump
flow, V-funnel, L-box and U-box tests were carried out to examine the performance of SCC. In
hardened concrete the tests were conducted and cured at different times to find compressive
strength, tensile strength and flexure strength test with and without partial replacement of marble
powder as a 10 %, 20% and 30% of cement in SCC for 14,28 and 56 days. Finally, the test results
showed increased strength with the addition of marble powder in SCC than the normal SCC apart
from this, durability of SCC also tested using RCPT, WPT; chemical attack tests like acid and
sulphate attack are conducted at the age of 28 and 56 days in SCC casted specimens. This study
concludes that up to 10% partial replacement of marble powder as cement for 28 and 56 curing days
which is compared with the conventional SCC were found to be satisfied
