— 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.
aggregate and coarse aggregate with rice husk ash, marble waste and coconut shell respectively at the ratio of 0%, 2%, 4%, 6%, 8%, 10% .each material is replaced at a time with same percentage.It is found that the compressive strength&flexural strength of …
— Coarse aggregate is considered as the most important component, which provides volume as well as strength to the concrete. It is mainly obtained from natural resources by quarrying rocks or dredging from the river bed. Every year, construction industries use huge quantities of natural aggregates, which leads to depletion of raw …

Strengthening of Concrete by using Oyster Shell and Marble Powder Khekiye Aye, Khatele Kenye, E Nainar, Akenyu Khing, Chelila Sangtam Abstract: Concrete is one of the most commonly used materials in the field of construction. The main ingredients of concrete mix are aggregate, sand, cement and water. Usually,
— 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].
Inorganic residual products like stone dust, crushed marble waste are used as green aggregates in concrete. This project summarizes the various efforts underway to …
Kanojia & Jain (2017) observed the effect of partial replacement of coconut shell as coarse aggregate in concrete and assessed the additional quantity of cement required to be added to account for ...

— Marble aggregates have a higher compressive strength and modulus of elasticity than fine aggregates, resulting in an increased strength. The sample with 20% recycled marble aggregate and 0.5% fibers exhibited the highest capacity. The compressive strength of this specimen is higher by roughly 22% compared to the reference specimen. …
— 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.
— As per the findings of Saloni et al., the alkali-activated concrete modified with marble aggregates in replacement of natural aggregates showed greater compressive and tensile strength values at 50% replacement of aggregates with marble aggregates than that recorded for 0% aggregate replacement. The increase in strength values was …
