Use of Limestone Powder to Improve the Properties of Self-Compacting Concrete Produced Using Cathode Ray Tube Waste as Fine Aggregate
This paper presents the effect of added limestone powder (LS) on the fresh and cured properties of self-compacting concrete (SCC) containing cathode ray tube glass waste. The concrete was produced using ordinary Portland cement at a water-cement (W/C) ratio of 0.38 by weight. CRT glass waste cullet was incorporated in river sand in proportions of 20 or 40%. To suppress potential viscosity effects limestone powder was added at levels of 5, 10, or 15% by weight. The slump flow time, slump flow diameter, V-funnel flow time, Marsh cone flow time, and setting time of the fresh concrete were tested, as well as the compressive strength and ultrasonic pulse velocity of the hardened concrete. The slump flow, V-funnel flow time, and Marsh cone flow increased with increasing limestone powder content, while the compressive strength and ultrasonic pulse velocity decreased. The results demonstrate that it is feasible to use limestone powder to produce SCC containing CRT glass waste as a fine aggregate replacement.
