Abstract:

Concrete is widely used in all kinds of projects. Improving concrete durability has great significance for the improving of the project service life. The selection of high quality raw materials is the basis for producing concrete, optimizing the concrete mixing ratio and producing durable concrete. The influence of the indexes of cements, mineral mixtures, aggregates and additives on the concrete durability is analyzed on basis of engineering practice.

Key words: concrete  , durability raw material
