Replacement Of Coarse Aggregate In Concrete [Civil Planets]

Using the E-waste as a partial replacement of coarse aggregate in concrete is the best solution. We can not fully replace material in concrete because it impacts the workability of concrete . The electronic waste is crushed as required particle size and can be mixed with other aggregates in concrete which will not affect the quality

What are the Materials for Replacement of Sand in Concrete

Jun 08, 2017· A concrete mix necessarily contents cement, water, fine aggregate and coarse aggregate. Aggregate occupy about 60 70% volume of concrete. In this percentage 40 to 50 % proportion of aggregate is fine aggregate (sand). Fine aggregate selection plays vital role in concrete performance and its cost.

Aggregate in Concrete The Concrete Network

Quality Counts. Make sure that your concrete producer purchases good-quality aggregate as verified by regular aggregate test results in compliance with ASTM C 33, "Standard Specifications for Concrete Aggregates." A history of good performance of a local aggregate also provides an indication of how well the material performs in service.
