1. The materail is easy to get. The sand and stone which occupied the 80%-85% of concretes are very cheap and easy to get.
2. Concretes with good formability is easy to cast and form, which can be shaped in required sectional form and outline according to the different application.
3. Good coordination. The concretes and rebar have strong cohesive force and close expansion coefficients.
4. Long durability. The concretes has high compressive strength and density.
5. Widely applicability. The concrete can be made into different strength level according to different projects requirements.
But the concrete has the shortcoming as heavy weight,less extension strength, easy to split, all these factors should be highly concerned.
