AGGREGATES & ITS PROPERTIES | PPT
FINE AGGREGATE :- The size of aggregate 4.75mm & smaller is called fine aggregate. Sand is generally considered to have a lower size limit of about 0.07mm. Material between 0.06-0.002 mm is classified as silt. Particles smaller than 0.002 mm are termed as clay. Loam is a soft deposit consisting of sand, silt & clay in about equal proportions.
