Aging and Curing Temperature Effects on Compressive Strength of Mortar Containing Lime Stone Quarry Dust and Industrial Granite Sludge
In this study, the researchers investigated the potential use of locally available waste materials from the lime stone quarry and the granite industry as a partial replacement of cement. Quarry sites and granite industry in the eastern province of Saudi Arabia produces tons of powder wastes in the form of quarry dust (QD) and granite sludge (GS), respectively, causing serious environmental prob...
متن کاملEffect of Characterization Properties on Compressive Strength of Concrete Containing Quarry Dust and Waste Plastic as Fine Aggregate
The scope of this study is to enhance the industry understanding of the sustainable utilization of quarry dust, and to identify any gaps in current knowledge. The term sustainable utilization implies the use of quarry dust to their full potential to meet the needs of the present, while at the same time conserving natural resources and finding ways to minimize the environmental impacts associate...
متن کاملProduction of artificial stone slabs using waste granite and marble stone sludge samples
In this work, the waste stone sludge obtained from the granite and marble stone processing factories was used for the manufacture of artificial stones using vibratory compaction in a vacuum environment. The results obtained showed that water absorption and density increased, and the flexure, compressive, and tensile strengths decreased with increase in the content of the waste stone sludge. The...
متن کاملEffect of Lime Stone Dust on Geopolymerisation and Geopolymeric Structure
In this paper, synthesis of geopolymer from fly ash with sodium hydroxide as activator was studied. Fly ash was replaced by Lime stone dust in various proportions (10% and 15%) where Fly ash was used as source material for synthesis of geopolymer. Sodium silicate (Na2SiO3) and sodium hydroxide (NaOH) solutions were mixed maintaining a silicate modulus (Na2O / SiO2) at 1. Scanning electron micro...
متن کاملthe effects of planning on accuracy and complexity of iranian efl students’ written narrative task performance
