Abstract

Concrete is the most widely used construction product because of its high structural strength and stability. Its main constituents are cement, sand, aggregates and water. Nowadays it has been comes in miscellaneous researches that to bypass these conventional ingredients in the evolution of sustainable development. These dissertation work covers the experimental study to observe the behavior of marble dust powder on replacement with cement for M25, M40 & M50 grade concrete, in this process we replace cement with marble dust powder at 0% to 15% with a constant interval of 2.50%, we made 7 batches including the batch of conventional mix also, the concrete was design mix for M40 & M50 grade, while M25 grade concrete was nominally mix, further we compare the properties of fresh concrete such as workability etc. observations were made that initial setting time and workability both increases for fresh concrete for all mixes, on the other hand when Physical properties of concrete were tested & compressive, flexural and split tensile strength achieved at 10% replacement of cement for M25 & M40 concrete, while this replacement limited up to 5% for M50 grade concrete, with this results we could say that this replacement is limited up to a small extent for high performance concrete. All specimens were tested at 7, 14 & 28 days curing age. It can be conclude that we can limit the use of cement content up to a certain extent to save both environment and economy, the later is very vital for any developing country.
