The evolution of civil engineering has recently resulted in new structural methods and greater consumption of aggregates, particularly sand. This evolution has led to an international dynamics of valuating local materials, such as crushed sand, which is not used sufficiently often due to the high rate of fine particles that it contains. The aim of this work is to study the influence of fine particles of crushed sands on the compressive strength and concrete slump. The experiments have been performed on crushed, river and dune sands and the results indicate that the behavior of concrete in the fresh and hardened states is different according to the composition and sands. The results were compared with Concrete Lab Pro 3 '' outputs. The analysis of the resistances shows that the experimental values and the estimated values are not comparable, especially in concrete slump. (C) 2015 Elsevier Ltd. All rights reserved.
