Abstract
Quarry dust was used as an alternate material for river sand both in conventional and also in coconut shell concrete. For any materials in concrete to be used in realistic situations, its strength and durability need to be examined. Therefore, this study examines durability performance of quarry dust as fine aggregate and coconut shell as coarse aggregate in concrete. Durability properties investigated include the absorption, volume of permeable voids, sorptivity, rapid chloride penetration test and salt ponding test. Tests were conducted at an age of 3, 7, 28, 56, 90, 180 days and one-year period of curing. The test results showed that the durability properties of quarry dust used concrete performed as a traditional one and coconut shell concrete are comparable to that of other conventional lightweight concretes.
