CORRELATION ANALYSIS ON THE EFFECT OF CHEMICAL COMPOSITION OF LIMESTONE AGGREGATE UPON MECHANICAL STRENGTH OF CONCRETE
Main article
Abstract
Limestone is a sedimentary rock that is no stranger in construction work due to its chemical composition, calcium carbonate, which has a cement-like characteristic when it is mixed with water, thus resulting in a binding agent to hold concrete together. It is a very popular choice to make cement but not as an aggregate. The main problem encountered is that there is not enough information on the appropriate amount of calcium carbonate within concrete. The purpose of this research paper is to study the effect of the chemical composition of limestone aggregate towards the mechanical strength of concrete. The objective is to study the relationship between the percentage of limestone aggregate and the mechanical strength of concrete. The extraction of data from past research papers about limestone aggregate percentage as its mechanical strength were tabulated where the parameters were analysed using the Pearson correlation analysis to study the strength of the relationship between the two parameters. The result shows the relationship between the two parameters is strong as when there was an increase in the percentage of limestone aggregate, the mechanical strength tended to also increase. The result obtained shows the relationship between parameters is strong which indicated that limestone is suitable to be used as concrete aggregate.
