Treatment on Coconut Shell to Improve its Quality for Use as Coarse Aggregate

Abstract:

To improve the quality of coconut shell (CS) to use as coarse aggregate different treatment methods are given to CS. Polyvinyl alcohol (PVA) and ferrous sulphate (FS) were used as materials for treating the CS. Ten different types of treatments were considered from raw CS to treat with PVA and FS. Significant reduction of water absorbing quality on CS was found from the different types of treatment given. Scanning electron microscopic (SEM) images were also taken and analyzed. SEM images obtained are exported into the software called ImageJ and analyzed in two different ways: one way is using 8 bits and other way is called RGB. An extract from the ImageJ software is given to support the results of treated CS aggregates. If the CS aggregates are treated, then no doubt that the water absorbing capacity of CS can be reduced.
