The Study of the Characteristics of Sand Concrete Based on Marble Waste Sand

Abstract

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.

“…Several studies came to the same results as we did, namely that adding NS 96 – 98 and NA 50 , 99 resulted in an increase in concrete density. Furthermore, the incorporation of nano 17 , copper slag 91 and marble dust 75 increase the concrete density . In contrast to NS and NA, increasing amounts of waste expanded polystyrene 100 and ethylene-vinyl acetate 101 are added to concrete, resulting in a significant decrease in density.…”

“…Similar our results, different studies showed that adding RHA 70 , NS 71 – 73 and NA 54 , 74 reduced the workability of the concrete. Furthermore, the incorporation of nanoclay 75 and marble dust powder 76 , 77 makes concrete mixtures stiffer, adversely influencing the workability of concrete. In addition, the workability of concrete containing recycled coarse aggregates (RCA) decreased as the percentage of RCA increased 78 , 79 .…”

The Comparative Study of the Performance of Concrete Made From Recycled Sand

“…Djebien and al, 2015 [9], in the formulation of a self-compacting concrete, substituted the sand of dune by a sand of marble waste with variable percentages of 25%, 50%, 75% and 100% respectively and found that recycled sand reduces density, air content, flow in a confined environment as well as mechanical resistance. Benhalilou and al, 2020 [10] in their studies on sand concrete, substituted 5%, 10%, 15% and 20% of the volume of dune sand by a marble waste sand, they found acceptable results from the point of view of workability, mechanical strengths and durability. In a research on mortars established by Hebhoub and al, 2020 [11], in which they substituted 5%, 10%, 15% and 20% of the volume of natural sand by a marble waste sand, the results show that the introduction of Recycled sand in mortars gives good results and can be used as aggregate.…”

Onyx Stone Waste As a Replacement of Coarse Aggregate In Concrete Mixture

“…This replacement can be done up to 100% and reach the optimal condition at 75 % aggregate replacement in the concrete mix. (Benhalilou et al, 2020) This coarse and fine aggregate Onyx waste as a substitute for coarse aggregate in concrete was able to improve the porosity value of the concrete (Kürşat Esat Alyamaç & Aydin, 2015). Concrete made from granite and marble wastes as aggregate still needs a plasticizer.…”
