Five concrete mixes A1, A2, A3, A4, and A5 were considered in different percentages of quarry dust in coconut shell concrete. Nine cubes were cast for each mix for 3, 7, and 28th day (totally 45 cubes) test and found density and compressive strength of all mixes. Deflection characteristics of all the five slabs, one slab in each mix were tested at 28 days ago and the results are presented. When the percentage of quarry dust increases, density, and compressive strengths are also increased. Deflection of slabs is decreased as the percentage of quarry dust increases. It shows that the quarry dust exhibits less deflection compared to river sand used concrete. All the slabs satisfy the IS 456: 2000 code requirement of span to depth ratio. This study encourages to use the quarry dust in place of river sand in case of the recently developed coconut shell concrete also.</Abstract> <AbstractLanguage>English</AbstractLanguage> <Keywords>Coconut shell; Quarry dust; Density; Strength; Deflection.</Keywords> <URLs> <Abstract>https://developer.ubipayroll.com/ubijournal-v1copy/journals/abstract.php?article_id=6323&title=STUDY ON THE EFFECT OF QUARRY DUST ON DEFLECTION CHARACTERISTICSOF COCONUT SHELL CONCRETE SLAB</Abstract> </URLs> <References> <ReferencesarticleTitle>References</ReferencesarticleTitle> <ReferencesfirstPage>16</ReferencesfirstPage> <ReferenceslastPage>19</ReferenceslastPage> <References>1.
