This study is part of the valorization process of local materials, which aims to reuse marble waste as fine aggregate (excess loads of marble waste exposed to bad weather conditions) available in the marble quarry of Fil-fila (Skikda, East of Algeria) in the manufacture of self- compacting concretes. It consists of introducing the marble waste as sand into the self-compacting concrete
13.09.2019· Mortars based on marble waste sand contain quantities of fine particles, which favor granular stacking during mixing and thus causes an increase in flexural strength. However, the marble waste sand is characterized by more acute and porous grains, so that the bond with the cement paste of the mixture is better .
The results obtained showed us that marble wastes can be used as sand in the manufacture of self compacting concretes.
Key words: Waste marble dust, very fine sand, concrete, dynamic modulus of elasticity, compressive strength, sorptivity. INTRODUCTION Marble has been commonly used as a building material since the ancient times. The industry’s disposal of the marble powder material, consisting of very fine powder, today constitutes one of the environmental problems around the world (Corinaldesi et al., 2010
01.03.2011· The main goal of this study is to demonstrate the possibility of using marble wastes as a substitute rather than natural aggregates in concrete production. The paper presents the study methodology, the characterization of waste marble aggregates and various practical formulations of concrete. This experimental investigation was carried out on three series of concrete mixtures: sand substitution mixture, gravel substitution mixture and a mixture of both aggregates (sand
bility of the marble dust instead of very fine sand passing through a 0.25 mm sieve at proportions of 0, 25, 50 and 100% by weight on the concrete. In this way, we will help to protect the environment by consuming the waste marble dust obtained as a by- product of marble sawing and shaping processes in the factories those operating in

01.10.2018· Environmental issue associated with marble waste disposal. Marble manufacturing involves cutting, polishing and finishing process to obtain marble from quarries. During these processes about 25% of original marble mass is lost in the forms of waste as marble dust and marble sludge . This marble waste is dumped in open lands, which gets suspended in the atmospheric air with time and is inhaled
The waste marble powder was milled by using a ball grinder and 1~5 mm zirconium balls as the milling media. Then the marble powder of large size was reduced into micrometer or submicrometer size, followed by screening with different meshes. 7 g of the milled and screened marble powder was added to 50 ml ethanol and stirred on a stirrer at a speed of 700 revolutions per minute (rpm). During the
The marble industry inevitably produces wastes, irrespective of the improvements introduced in manufacturing processes. In the marble industry, about 50 to 60% production waste. These waste create many environmental dust problems in now a day to day society. In requiring a suitable form of management in order to achieve sustainable development. In this paper explained about the behavior
Hence the reuse of waste material has been emphasized. Waste can be used to produce new products or can be used as admixtures so that natural resources are used more efficiently and the environment is protected from waste deposits. Marble stone industry generates both solid waste and stone slurry. Whereas solid waste results from the rejects at the mine sites or at the processing units, stone slurry is a
In this work, the existing excavated soil is stabilized with waste materials. The wastes consisted of fly ash, marble dust and waste sand. The percentage addition of waste materials was 5%, 10%, 15% and 20% (by mass) of the existing soil. The soil/waste specimens were cured for 1, 7, 28, 56, 90 and 112 days before testing. Testing included the dry unit weight and unconfined compressive strength ( qu) as well
09.07.2014· The polymer concrete with marble waste is of great interest because the marble addition or the marble used as aggregates improve the properties of concrete and contribute to a reduction of polymer content. The marble waste can also be used in the production of other building materials, such as ceramic products, where can be used as mix component, or in asphalt production as aggregate sort.
Marble stone industry generates both solid waste and stone slurry. Whereas solid waste results from the rejects at the mine sites or at the processing units, stone slurry is a semi liquid substance consisting of particles originating from the sawing and the polishing processes and water used to cool and lubricate the sawing and polishing machines. Stone slurry generated during processing corresponds to around
