Study of the Reinforcement of Limestone Mortars by Polypropylene Fibers Waste

The first objective of this study is the valorisation of limestone waste produced from the crushing stations by using it as fine sand for mortars mixes and hence replaces the river sand. The second objective is the reinforcement of mortars by polypropylene fibers waste coming from the fabrication of domestic brushes and sweeps. In this paper we presented the results of physical and mechanical properties of reinforced mortars prepared with limestone sand which is in abundance in the city of Laghouat situated in 400km in the South of Algiers. The fibers dosages used are: 0.5, 1, 2 and 4wt% with length of 10, 20 and 30mm. The results of this investigation put in evidence the efficiency of the reinforcement of limestone mortars by polypropylene fibers waste in the improvement of their flexural tensile and compression strength. © 2010 Published by Elsevier B.V.
