Mechanical Behavior of Recycled Fine Aggregate Concrete with …
This study investigated the mechanical behavior of normal strength (NS) and high strength (HS) concrete containing recycled fine aggregates (RFAs). A high slump mixing design was employed, which may be potentially used as filled structural concrete. The compressive strength, tensile strength, and elastic modulus were measured according to the RFA …

Sand: The Fine Aggregate
The fine and coarse aggregates generally occupy 60–70 % of the concrete volume and influence markedly the concrete's properties, mixture proportions, and economy. Properties of fine aggregate (sand) affect concrete properties such as durability, strength, thermal properties, unit weight, and surface friction.

Difference Between Fine and Coarse Aggregate
The surface area of coarse aggregates is less than fine aggregates. 6: Function in Concrete: The voids between the coarse aggregate are filled up by fine aggregate. Coarse aggregate acts as inert filler material for concrete. 7: Uses: Fine aggregates are used in mortar, plaster, concrete, filling of road pavement layers, etc.

Compared to recycled coarse aggregate concrete (RCAc), recycled fine aggregate concrete (RFAc) has been less studied, but RFA is also important in replacing sand in the preparation of concrete. The application of RFA has a positive impact on the environment . However, the application of RFA is limited in various ways due to its many drawbacks.

Mechanical properties of recycled fine aggregate concrete incorporating
The current studies on the workability, mechanical properties, and durability of recycled fine aggregate concrete (RFAC) showed that: (1) the slump of fresh RFAC declined with an increase in RFA replacement ratio due to the rougher surface texture and greater angularity of RFA [21]; (2) the RFA had a significant negative effect on the mechanical properties of …
