aggregate particles improve the workability of fresh concrete during mixing so they are good for preparing portland cement concrete. * Angular and rough particles are good for asphalt concrete and base courses because they increase increase the stability of the materials in the field and reduce rutting. * Flaky and elongated aggregates are difficult to compact during construction and are easy to break so they are should not be used for asphal concrete. * Soundness and Durability: * Soundness

Q3: Describe and discuss the durability properties of hardened concrete. Durability is the ability of concrete to handle deterioration from the surroundings or at the service in which it is placed. The most important things that cause rust could be divided into two chemical and physical causes. The Chemical durability complications are disturbed with countless formulae reactions of cement-aggregate. On the other hand In the physical durability aspect problems are concerned from the aggregates
