Development of High Strength Lightweight Coconut Shell Aggregate
Hence, coconut shells can be used as coarse aggregate for production of structural lightweight concrete [11,12,13,14]. Water absorption of coconut shell aggregate concrete (CSAC) was more compared to other lightweight concrete but these property can be improved by proper curing and seasoning of coconut shells before using as aggregate .

density shows a significant change in density and optimum water content with change in gradation in similar aggregate types. Therefore, it is recommended to use relative density values correlated to gradation for compaction control of aggregate materials in the field to avoid inadequate compaction. A relative density of at least 70% is recommended.
