Concrete aggregates are composed of geological materials such as gravel, sand and crushed rock. The size of the particles determines whether it is a coarse aggregate (e.g. gravel) or a fine aggregate (e.g. sand). The resulting concrete can be used in its natural state or crushed, according to its use and application.
view moreThis present study examines the possible reuse of waste glass crushed into fine and coarse aggregate sizes as partial substitute for natural fine and coarse aggregate in concrete. The variables in this study is both the fine and coarse aggregate while the cement and water-cement ratio were held constant.

Using fine crushed aggregate does not increase compression strength, however it helps to decrease voids in the sample that makes it denser and thus increases compression strength of concrete. 3.
view moreThis study aimed to explore the possibility of utilizing crushed glass as an alternative fine aggregate for concrete by replacing concrete with crushed glass. Specifically, the study sought to assess whether there is a significant correlation between crushed glass volume in concrete and its compressive strength and also between sand volume in ...

As fine aggregate comprises up to 30% of the total volume of concrete, consequently gradation and fineness modulus of sand are among principal factors affecting the performance of fresh and hardened concrete.

view moreFine aggregate should fall within gradation limits provided in ASTM C 33, Section 6. If there is a deficiency in a locally available fine aggregate, concrete may benefit from the addition of air entrainment, additional cement, or a supplemental cementitious material (SCM) to address these shortcomings.
