When the base course is constructed entirely of the fine aggregate type material, the asphalt wearing surface should be 4 inches to 5 inches thick, as may be seen from Figure 1, for the service bearing capacity of fine aggregate type materials is about 50 psi. to 65 psi. The use of the coarse aggregate type material in constructing a base
بیشترFine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's …

بیشترThe size of fine aggregate is defined as equal to or less than 4.75 mm. This means that the aggregates that can pass through a number 4 sieve with a mesh size of 4.75 mm are referred to as fine aggregates. These include clay, silt, and sand. Crushed gravel and crushed stone can also fall under this category.
بیشترThe gradation of the final aggregate base material shall meet the requirements of the gradation given in Table 209-2 when tested per ATM 304. The gradation shall be well graded from coarse to fine and shall not vary from the lower limit on one sieve to the high limit on an adjacent sieve or vice versa.

بیشترThe aggregates are graded as per IS code 383, when the aggregate size is less than 4.75mm is called fine aggregate & more than 4.75mm is called coarse aggregate. The aggregate gradation is determined by the fineness modulus method where aggregates are passing through the sieve as per IS standard to classify its size.

بیشترQualities of fine aggregates: Fine aggregate should be clean i.e. it should be free from lumps, organic material, etc. It should be strong and durable. It should not react with cement after mixing. Also, it should have a tough floor. It should not absorb greater than 5% of water. These types of aggregates should not be soft and porous.
