Valorisation des bétons à base de granulats recyclé -granulats de brique - sous l'effet de temperature

Abstract

Concrete today is the most commonly used materials in the area of construction the granules are in the average of 70% to 75% of the size of concrete. For this purpose it is necessary to study the possibility of restoring the brick waste that is plentiful in the brick factories as an alternative to the natural granulat and now considered the recycling of waste and recovered a solution of the future in order to fill the gap between production, consumption and environmental protection. The aim of this research to the study of mechanical behavior and concrete based on recycled debris (brick grains).Under the influence of temperature to take full advantage of his qualities, with the knowledge that the fire resistant regular low aggregate. First of all there are two types of concrete regular concrete and the brick, it is with different rates as an alternative building materials and emectric power.After that concrete under different temperatures (300 to 600) degree celsuis. And finally, it was noted the development of concrete prestressing based on recycled debris of bricks under the influence of temperature using the loss of bloc and strength tests pressure. Concretes with brick aggregates show good resistance results even at temperatures of 300 ° C and 600 ° C, and we also note that concrete with a high percentage of brick aggregates has the best compressive strength compared with ordinary concrete
