Laboratory Evaluation of the Performance of Recycled Aggregate Concrete Containing Construction and Stone Factories Waste in Terms of Compressive and Tensile Strength

الملخص EN

Nowadays, the rapid growth of waste production and, especially, construction wastes has become one of the main problems in societies.

In the world, reinforced concrete structures are destructed for different reasons.

These destructions generate increasing values of waste.

Furthermore, there are several stone factories in every region that produce a large volume of decorative construction stone wastes.

This experimental study has investigated the effect of using recycled aggregates of construction and stone factory wastes in concrete production.

Different tests were performed on concrete samples in fresh state (slump) and hardened concrete (compressive and tensile strength and modulus of elasticity).

The optimal percentage for replacement of each of the recycled materials was determined based on comparing the results of laboratory tests.

Finally, a proper mix design was proposed for both recycled aggregate samples, and a comprehensive report of the results was also provided.
