Coarse Aggregates: Types, Properites & Applications

2020-12-17 · 2.Shape of Coarse Aggregates: The shape of the aggregate is a crucial characteristic because it impacts the workability & strength of the concrete. In general, the angular aggregate is desirable for round and smooth sets for the following reasons: The angular aggregate shows better interlocking effect which gives a better concrete.

Study on Replacement of Coarse Aggregate by E

E- waste is used as one such alternative for coarse aggregate. Owing to scarcity of coarse aggregate for the preparation of concrete, partial replacement of E-waste with coarse was attempted. The work was conducted on M20 grade mix. The percentage of replacing coarse aggregate with E-waste in the range of 0%, 5%, 10%, 15%, and 20%.

A Study on the Utilization of Coconut Shell as Coarse

2019-7-1 · coarse aggregate with coconut shell aggregate is determined from the study. Coarse aggregate made from coconut shells were used in proportions of 5%, 10%, 15%, 20%, 25%, 30% and 35% to replace coarse aggregate in conventional concrete. A constant water to cement ratio of 0.5 was used throughout the study.

EFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON

2014-1-8 · There has not been much research on the effects of coarse aggregate content on the fracture energy of concrete. One study, conducted by Moavenzadeh and Kuguel (1969), found that fracture energy increases with the increase in coarse aggregate content. Since cracks must travel around the coarse aggregate particles, the area of the

Aggregates for Concrete GreenSpec

• ‘Aggregate’ is a term for any particulate material. It includes gravel, crushed stone, sand, slag, recycled concrete and geosynthetic aggregates. Aggregate may be natural, manufactured or recycled. • Aggregates make up some 60 -80% of the concrete mix. They provide compressive strength and bulk to concrete.
