Abstract: This experimental study was aimed at evaluating the effect of plastic fibres waste on the physical and mechanical performances of mortars prepared and conserved under hot-dry conditions. The used fibres are recycled polypropylene fibres coming from industrial waste. Two dosages of fibres are used 0.5 and 1 % by weight. The results showed that the exposition of mortars to hot-dry conditions reduces their long-term mechanical strength and increases their shrinkage. Under hot-dry conditions, the reinforcement of mortars by plastic fibres waste has a positive effect on their flexural and compressive strength. The shrinkage of mortars conserved under these conditions is reduced by the addition of plastic fibres waste.
