Previous research has identified inadequate flexibility in concrete pavements due to the use of high-strength concrete mixtures. This research investigates whether this problem can be addressed by partially replacing some fine and coarse aggregate components with waste rubber from shredded tires, the safe disposal of which otherwise is a major environmental concern.

Aggregates less than 4.75 mm in size are called fine aggregates; sand falls under the fine aggregate and crushed stone or metal under the coarse aggregates. Here we will learn about fine aggregates, types of fine aggregates & much more.
This study aims to develop high strength rubberized concrete by utilizing large amounts of fine materials and replacing 15% and 25% of the natural aggregates by volume with a well graded mix of ...
(5-10mm), and fine aggregate (0-5mm). Table 1 illustrates the aggregate composition used for the HRS-Base mixture to achieve Indonesian National Standard (SNI) specifications. Based on aggregate combination analysis, proportion of the aggregate composition is as follows: 27% coarse aggregate, 20% medium aggregate, and 53% fine aggregate.
Qualities of Fine Aggregates: Good quality fine aggregates are free from impurities. It should not make any reaction with cement. Fine aggregate should not absorb more than 5 percent of water. Uses of Fine Aggregate. It is used to prepare mixed concrete. It is used to prepare mortar for masonry work. Fine aggregates are used to fix interlocks.
