Synopsis
The purpose of this research project was to investigate the suitability of crushed basalt sand and marine dredged coral sand as an alternative to lagoon coral sand for plastering and rendering purposes. To achieve this objective, investigation were carried out in 3 stages.
Assessing and comparing the properties of the two sands under investigation with lagoon coral sand, the sand traditionally used in the construction industry for plastering and rendering.
Incorporate the different sands in mortar and to develop optimum mixes for each sand.
Investigate the shrinkage properties of the optimum mixes and to simulate internal plastering and external rendering as done on sites so as to compare the characteristics of each sand when used in plaster or render.
