“…These results are consistent with those obtained by López et al (2007) [32] and unlike those obtained by Alves et al (2014) [16]. The introduction of MS as a partial substitution of DS increased the reference concrete density up to a maximum value of 2.40 g/cm 3 for concrete at a 20% substitution rate, this increase can be explained by high density of MS in comparison to DS (Djebien et al 2015) [33]. For formulation SCWS-C, an increase in the CS substitution rate causes a decrease in density up to 2.32 g/cm 3 ( Fig.…”

“…(2018) [35]. The decrease in entrapped air content for formulation SCWS-10M is due to the improvement in segregation resistance capacity of marble waste sand [36,33]. However, a decrease in the occluded air content as a function of the increase in CS waste rate can be explained by a higher fine content which contributes to reducing the porosity of concrete.…”

The introduction of treated plant fibres into sand concretes leads to a reduction in density, improved ductility and thermal conductivity, and makes sand concrete an environmentally friendly and ecological material. The recovery of waste in this type of material allows the production of new ecological and sustainable materials used either in the new construction or in the rehabilitation of old buildings. In this context, a comparative study was based on the valorisation of marble and ceramic waste as sand in sand concrete made from straw fibres. To carry out this study, we introduced these wastes at substitution rates of 10% and 20%, separated and mixed, and studied the development of the properties of these concretes (density, workability, air content, compressive strength and bending tensile strength) and their behaviour with respect to durability (capillary and immersion absorption and chloride penetration). The study shows that the recovery of this waste as sand in sand concrete based on straw fibres gives satisfactory results. The chemical resistance, thermal conductivity and microstructure are under study, the results of which will be the subject of another publication.

“…The volume of occluded air decreases slightly from 7.4% for the reference mortar to 4.8% for the mortar incorporating 15% of marble waste sand. The significant reduction in the volume of air entrained in composite mortars of marble waste sand is related to the increase in the compactness of the mixtures following the substitution of natural sand by marble waste sand [11]. At early ages (2 and 7 days), and through Figure 10, the compressive strengths of mortars based on marble waste sand presented higher strength than that of control mortar, except for mortar with 5%.…”

The aim of this research is to study the possibility of the valorization of sand marble waste in mortars as substitute in sand. To achieve this study, sand marble waste is used with weight ratios of 5, 10, 15 and 20% to formulate a mortar with sand marble waste and a control mortar with 0% of sand marble waste. The properties in the fresh state, the mechanical strength, absorption by immersion, and the weight loss as well as the shrinkage and acid attack of each mixture were carried out through the conducted experiments. The different results show that the introduction of recycled sand in the mortars gives good results and it can be used as aggregates.

“…Capillary and immersion absorption are reduced to a rate of 10%. When Djebien et al [11] used marble waste fines from the Fil-fila quarry which partially replaced limestone fines in sand concrete, they found an improvement in the properties in the fresh and hardened state as a function of the increase in the rate of fines. This paper, presents an experimental study to evaluate the effect of marble waste on the properties of sand concretes in order to specify its fields of application and define the data necessary for the sizing criteria.…”

The present study aims to valorize the waste and in particular the waste from the Fil-fila quarry. The main reason for choosing the waste from this quarry was the need to reduce the impact on the environment (by reducing stockpiling) and the raw material cost (economic reason). This study therefore consists in recovering this type of waste (discarded powder subject to weather changes) as sand in partial replacement of dune sand in the formulation of sand concrete with percentages of 5, 10, 15 and 20 %, by studying the behavior of these concretes in the fresh state (workability, density and occluded air) and the properties in the hardened state (compressive and tensile strength by bending, absorption by immersion, shrinkage and weight loss, chemical effect of HCl and H2SO4 solutions), and subsequently comparing the results obtained with reference samples (0%) based on ordinary sand. Based on the obtained results, it can be concluded that the substitution of ordinary (dune) sand with marble waste sand provides acceptable results from the point of view of workability, strength and durability.These observations are likely to widen the field of applications of these sand concretes based on marble waste.
