 — Exposed aggregate concrete is concrete that displays stones, pebbles, sand, recycled glass, or shells in its design. It comes in a range of colors, textures, and styles. When pouring exposed aggregate concrete, a contractor removes the top layer with a chemical inhibitor, water washing, or etching.

 — 2.1. Use of marble waste as a partial replacement for conventional coarse aggregate. Marble waste was judged as a potential replacement for conventional coarse aggregates first by Binici et al. (Citation 2008).They had compared the behaviour of concrete mixes completely made with marble waste as coarse aggregate with mixes …

 — Choosing the best aggregate for your concrete requires an understanding of how this concrete is poured and finished. For example, if your flooring team is laying standard exposed aggregate concrete, you'll …

 — Granite powder and cockle shell are adopted as partial replacements to fine and coarse aggregate respectively. It is concluded from the study that maximum strength is attained with a combination of granite powder and cockle shell at 20% and 15% partial replacements of fine and coarse aggregate respectively for M30 grade Concrete.

 — Sometimes people were even told to expect exposed aggregate concrete to lose its decorative stones over time. But today exposed aggregate finishes are emerging as beautiful and durable architectural paving including patterned reveals, multiple stones like marble, shells, or glass, and finishes from sand size upward. THE PROCESS

 — In all the variations 10%, 20%, and 30% of aggregates were replaced by their volume. e-plastics and CS used in this concrete were shredded and gridded to achieve sizes similar to natural aggregate.

 — Generally, the inclusion of oyster shell as fine aggregate replacement affects the fresh and mechanical properties of concrete owing to the different characteristic of this waste as compared to sand. Commonly, the incorporation of seashell waste as aggregate in mortar or concrete decreases the workability of mix [35].

 — Self-compacting concrete (SCC) is also seen as unsustainable since it uses a lot of natural resources. Recent researchers have focused on lowering construction costs and partially replacing cement with industrial waste. It is possible to effectively use various industrial wastes in concrete as cement or aggregates. Among these wastes, waste …

 — The optimum substitution level of clay with 0 to 25% coarse aggregate with incremental increases of 5% is replaced by coconut shell in concrete. At the ages of 7 and 28, it was revealed that the maximum strength achieved in concrete is 10% cement replaced by clay with 10% coconut shell as a coarse aggregate substitution level.
