The sugar industry in Egypt dates to the beginning of the nineteenth century. The sugar industry waste in Egypt has been used for recycling and use in the fields of agriculture and industry. Also, some waste has recently been used in the construction field. In this research, we will studies the effect of using dry vinasse which is one of the sugar industry waste on some hardened concrete properties and properties of durability, by studying the addition of various proportions of dry vinasse between 0.2 to 0.5% of the cement weight of dry vinasse, on cement mixtures 3, 3.5, 4 Kn/m3 and pouring concrete into standard cubes, beams and cylinders and curing it by submerging it in water until hardened concrete tests are performed every 28, 90, and 180 days and the durability test is done after 180 days after the cubes are curing in water for 28 days and then immersed in a solution 10% sodium sulfate.
The results showed a noticeable improvement in both the compressive strength, flexural and splitting strength of concrete. Likewise, the concrete improved its resistance to deterioration after immersing the concrete cubes in sodium sulfate solution. The most favourable dose of dry vinasse is 0.4% dose.
