STUDY THE PROPERTIES OF HIGH STRENGTH CONCRETE WITH ADDITION AND ALTERING THE LIMESTONES DUST AND MARBLE DUST

civil engineering

Because of constantly expanding amount of waste materials and developing ecological mindfulness, solid waste management is the prime concern in the world. Scarcity of resources and daily increase in demand, the world is surprisingly turning to investigate properties of waste material and finding its valuable properties so that it may use as a replacement of these natural resources. The experimental investigation was performed to evaluate the strength and durability etc. properties of high strength concrete M40 and M60 grades of concrete mixes, in which natural sand was partially replaced with Marble dust, Limestone dust and mix of Marble dust & limestone dust (LIMA), with five percentage (0%,25%,50%,75%,100%). Slump test, compression test and flexural strength test were carried out to evaluate the strength of concrete. The Test results were clearly showing that there is increase in compressive strength and flexural strength for both grades of concrete mixes (M40 and M60) with inclusion of Marbledust, Limestone dust and mix’s of Marble dust & limestone dust (LIMA) up to 50% replacement.Percentages increase of strength is higher in marble dust for both grades of concrete with any percentage replacement
