Recycle of E-Waste in Concrete

Benefits of recycling are extended when responsible recycling methods are used. Concrete mixes with different percentages of E-waste were casted. It has been decided to make three different types of conventional specimens with partial replacement of E-waste on a percentage of 10%, 20%, and 30% to coarse aggregate with water cement ratio of 0.45.

Specific Gravity of Coarse Aggregates: Its Importance

As per the definition given in the ‘IS: 2386 (Part III) 1963’, (Indian Standard- Methods of Test for Aggregates for Concrete Specific Gravity, Density, Voids, Absorption and Bulking), the specific gravity of coarse aggregates is the weight of the aggregates dried to constant weight in an oven at 100°C divided by its absolute volume including the natural voids within the aggregate

Aggregates Types of Aggregates Coarse Aggregate, Fine

Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar. Those particles that are predominantly retained on the 4.75 mm (No. 4) sieve, are called coarse aggregates. Those particles passing the 9.5 mm (3/8 inch)

Electric Arc Furnace Slag as Coarse Recycled Aggregate for

Oct 01, 2015· Electric arc furnace (EAF) slag is a by-product of steel production in electric arc furnaces. Several studies have tried to demonstrate its suitability in civil engineering application, such as in bituminous mixtures and cement-based materials, due to its good physical, chemical and mineralogical properties. Particularly the re-use as coarse aggregate for concrete production has been shown to

Functions Of Fine and Coarse Aggregate in Concrete Civil

3. It helps to prevent possible segregation of paste and coarse aggregate particularly during the transport operation of concrete for a long distance. 4. Fine aggregate reduces the shrinkage of binding material. 5. It prevents the development of a crack in the concrete. 6. It fills the voids existing in the coarse aggregate.
