Characteristics of Aggregates Civil SnapshotWHAT ARE THE PROPERTIES OF AGGREGATES FOR CONCRETE

Aggregates must conform to certain requirements and should consist of clean hard strong and durable particles free of chemicals coatings of clay or other fine materials that may affect the hydration and bond of the cement paste The characteristics of the aggregates influence the properties of the concreteDec 07 32 There is little mistake in your question actually columns are prepared by pouring concrete in formwork with reinforcement The concrete used for preparation of columns has different grades acccording to its strength Grades of concrete M10 M15 M20
