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

Abstract

— This 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 was found to be satisfied.
