  • Replacement Of Coarse Aggregate In Concrete - Civil Planets

    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 and durability of the concrete. The partial e-waste concrete also named E-crete concrete. Construction Waste Material

    PDF Partial Replacement of Coarse Aggregate with Broken

    Abstract— The study reports on experimental investigation on the suitability of the use of broken tiles as partial replacement for crushed granite in concrete production. Control mixing ratio of 1:2:4 batched by weight with water – cement ratio of 0.55 was used. The percentage replacement varied from 0% to 40% at intervals of 5%.
