Aggregates. Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the ...Web
ادامه مطلبGravel. Gravel typically has a void ratio about 0.4, regardless of whether it is well or poorly graded, although the void ratio can be affected by the presence of impurities, such as clay or silt. Gravel with clay has a void ratio of about 0.25, while gravel with silt can have a void ratio of 0.2 or less. Did you find this page helpful? 👍. 👎.Web
