FRESH AND HARDENED STATE PROPERTIES OF SCCs PREPARED WITH LIMESTONE-BASED MANUFACTURED AGGREGATES AND POWDER

Abstract

Because the amount of sand and gravel extracted from natural resources is quickly depleting, the use of manufactured aggregates is becoming increasingly important in terms of sustainability. In this study, crushed limestone and filler material were used as both sand and coarse aggregate and powder material. As a result, all of the concrete components' grains had an angular form and a rough surface. Self-compacting concretes (SCC) were made with a maximum aggregate size of 10 or 16 mm and cement content of 350 kg/m3. The amount of limestone fine was raised in increments of 100 kg/m3 up to 300 kg/m3. The effects of fine material amount and maximum coarse aggregate size on spreading, flow, passing ability through the obstacles, segregation, and rheological properties of SCCs were determined. Although the mixtures' slump flow performances remained in the SF2 and SF3 classes according to EFNARC standards, longer V-funnel times and larger J-ring differences were obtained when compared to slump flow values, particularly for 16 mm aggregate size. The hardened state properties of concretes were examined by measuring the compressive and splitting tensile strengths, modulus of elasticity and Poisson ratio.
