Effect of Limestone Aggregate on High Strength Concrete in Both Fresh and Hardened States
Journal Title: GRD Journal for Engineering - Year 2016, Vol 1, Issue 12
Abstract
Limestone is mainly constituent of chemical compound calcium carbonate (CaCo3). It is basically called sedimentary rock substance. As per researchers it forms 10% of total volume of Sedimentary rock. The extrusion & Implementation of limestone in any form deals with ease of work and as a less pollutant for Environment, hence it can be massively used and utilized as a replacement to coarse aggregate in construction. This study deals with introduction of usage of local available limestone aggregates in concrete mix as a replacement for using normal coarse aggregates. In this research article Effect of limestone aggregate on Fresh and Hardened properties of high strength concrete were discussed, Substitution of the Local Available and Naturally occurring limestone aggregates as an Partial replacement for normal coarse aggregate material made for M50 grade .Adopting a suitable W/C ratio, Number of Specimens were casted and tested for different ages. The tests were conducted on casted specimens and results were discussed in detail in the discussion part of the article. From the test results, it clearly shows that usage of limestone aggregates in concrete will lie in range between 50% - 75 % replacements for M50. On further addition of Limestone aggregates in concrete it leads to decrease in strength properties and swelling is observed cause of repulsive charges of aggregates.
