Replacement of RCA for natural coarse aggregate by up to 45% by volume had no significant effects on any of the properties. These results indicatethat high-quality RCA can be used as areplacement for a portion of the

Evaluating the Prolonged Properties of Fresh Self

This paper aims to investigate the properties of fresh self-compacting concrete incorporating recycled aggregates (RSCC) over time. Recycled aggregates included crushed red brick and crushed ceramic. Recycled materials were used to replace the dolomite used as coarse aggregate in control mixes. The replacement ratios were 25, 50, 75 and 100

Properties of Hardened Concrete with Blast Furnace Slag

The physical properties of Ground Granulated blast furnace slag (GGBFS) provides advantages to the concrete in fresh state as well as in its hardened state. It is always recommended for a concrete mix design, that would provide us with a denser mass of concrete, i.e. a solid that is free from voids. GGBS play an important role in making the
