Strength Characteristics of Self-compacting Concrete partially replaced with Waste Marble Powder
J. Environ. Nanotechnol., Volume 7, No 4 (2018) pp. 46-50
Abstract
Self-compacting concrete is one of the most revolutionary developments in concrete research; this concrete is able to flow and fill the most congested places of the formwork without vibration. The properties of self-compacting concrete after the replacement of fine aggregate with waste marble powder at different percentages (0, 10, 20, 30, 40 and 50%) have been investigated in this work. The waste marble powder, finer than 4.75 mm, was used for the replacement of fine aggregate. With the increment in the dosage of waste marble powder, the workability of self-compacting concrete has increased. For the dosage of 30%, the properties observed were better than other dosages. The compressive strength tests were conducted at different mix proportions and the highest compressive strength was found at 30% dosage at 7-day and 28-day ages.
