Abstract

Highlights: Waste marble slurry used as an important resource in concrete and reducing the carbon footprint of cement. Long-term strength and durability performance of concrete on partially replacing cement by weight by dried waste marble powder slurry assessed. Both Mechanical and durability parameters of hardened concrete tested for a period of 1 year after exposing samples to adverse environmental conditions. Marble slurry replacement percentages kept as 10%, 15%, 20%, 25% and water binder ratios as 0.35, 0.40 and 0.45. Surface mesh for variation in all the properties with different replacement levels, curing conditions and water binder ratios plotted. Relationship between mechanical and durability properties with compressive strength derived for marble slurry incorporated concrete. Abstract: Present study assesses and evaluates the long-term strength and durability performance of concrete on partially replacing cement by weight by dried waste marble powder slurry. Four different replacement percentages (0, 10, 15, and 20 and 25%) and three water-binder ratios (0.35, 0.40 and 0.45) have been tested in the paper. The main reason for the study is to check whether use of dried marble slurry affects the properties of concrete in long term as the amount of binder is reduced, when cement is partially replaced. Long-term impact is analyzed by testing the concrete samples for 28, 56, 90, 180 and 360 days after curing the specimens in water for 28 days and exposing the samples to adverse environmental conditions in the state of Rajasthan, India where the temperature ranges from 0 °C in winters to as high as 47 °C in summers. The concrete mixes were tested for strength parameters mainly compressive, tensile and flexural strength, also durability parameters water permeability, abrasion resistance and water sorptivity. Surface mesh for variation in all the properties with different replacement levels, curing conditions and water binder ratios are plotted in the paper. Based on the analysis of concrete with various replacement levels of marble slurry, it can be concluded that for up to 15% replacement, an enhanced physical strength and durability of concrete blocks was observed across testing periods of 28 days to 360 days. It was observed that marble dust generated an effective dense mix for higher replacement ratios, thus improving the properties in long-term duration. Finally, relationship between strength and durability properties with compressive strength are derived for marble slurry incorporated concrete.
