Egg Shell As A Fine Aggregate In Concrete For Sustainable Construction S.A. Raji, A. T. Samuel ABSTRACT This work has investigated the potential use of usedegg shell as a concrete material. The usedegg shells were used as fine concrete aggregate. In the laboratory test, conventional fine aggregate was replaced at 100 replacement level.
Most agencies specify using the material directly in the project that is being reconstructed. Recycling of concrete is a relatively simple process. It involves breaking, removing, and crushing existing concrete into a material with a specified size and quality.
Jul 02, 2019 “Often, recycling centers will crush old concrete into sizes suitable for use in driveway base materials, or even the final gravel layer,” he says. Asphalt Cost $2 to $5 per square foot.
The main reasons why it is not acceptable for concrete making is the presence of sea shells and the chloride content. Raw Sea Sand. Fine Sea Shells in Coarse Fraction. Sea Sand After Washing. It has been argued that shell content has no adverse effect on the strength of concrete as such, but the workability is reduced.

To make concrete though which will greatly extend the volume produced you mix in gravel or sand or crushed brick. Proportions are an endless subject of debate but the formula of 1 part cement, 2 parts sand and 3 parts gravel by volume is a good starting point. Mix the dry ingredients first and then slowly add water. You want workable concrete.
As it is crushed into small pieces, this concrete allows water to permeate the driveway. Crushed Shell. The porous nature of crushed shells allow plenty of water to penetrate into the ground and prevents harmful runoff. You can get a unique look while making an environmentally friendly choice.
