Coconut Shell Powder As Fine Aggregate In Concrete

PAPER OPEN ACCESS Mechanical properties of concrete with .

The coconut shells were collected from the local market and exposed to the sun to dry for one week, then they were crushed by a mini crusher to produce fine coconut shell aggregates (CSA). Figure 1(a) and (b) show coconut shells as fine and coarse aggregates, respectively. The length of fine CSA was made between 1.18 mm to 4.75 mm.
