Concrete mechanical properties could be improved through adding different materials at the mixing stage. Quarry dust (QD) is the waste produced by manufactured sand machines and comprise approximately 30–40% of the total quantity of QD generated. When it dries, it transforms into a fine dust that poses a tremendous hazard to the …
The use of quarry dust in concrete is desirable as a useful disposal of a by-product, reduction of river sand consumption and increase in strength. Quarry dust has different shaped particles like rough, sharp and angular, helps in better interlocking and to gain strength. It is the waste material remained after crushing of rocks.
•. Compressive strength improves up to an optimum replacement level of 60% replacement. •. Split tensile strength increases up to 15% fine aggregate replacement and then decreases. •. Increase in Modulus of Elasticity of concrete blocks observed up …
The result shows that 25% of quarry dust and 75% of cement is the best percentage that can be used in concrete mixture to reach the standard strength. From an economic point of view, the proposed ...
chemical characteristics of quarry dust in relation to the codal requirements that are met. When sand is completely replaced with quarry dust, compressive strength tests produce better results. 3. MATERIALS AND METHODOLOGY 3.1 Materials used 3.1.1 Cement As it is generally known, cement is a complex material created by
The partial replacement of quarry dust gave a 28 days' peak compressive strength at 40% replacement level and decreases for 50% …
This research investigates concrete prepared using alccofine and quarry dust. Tests were conducted to assess their workability, density stability, water absorption, the initial rate of absorption, compressive strength, and split tensile strength characteristics. concrete was prepared with a target density of 1200 ± 50 kg/m3.
The physical properties of Quarry dust are fineness modulus, specific gravity, loose density, compacted density and grading zone are 3.1, 2.85, 1460 kg/m3, 1610 kg/m3 and IV zone respectively. The chemical properties of quarry dust are silica, Alumina, Iron, Megnesium oxide and calcium oxide are 60%, 3%,3%,1% and 23% …
The proportion of 25% laterite to 75% quarry dust and 50% laterite to 50% quarry dust with 0.6 water cement ratio produced workable concrete with good structural characteristics; iii) The density of hardened concrete …
Research were done to determine the optimum percentage of quarry dust in concrete. The result shows that 25% of quarry dust and 75% of cement is the best percentage that can be used in concrete mixture to reach the standard strength.
the quarry dust. 3. The compressive strength and split tensile strength of concrete for grade M30 with quarry dust as fine aggregate were found to be comparable with the concrete made with the river bed sand. 4. The increase in compressive strength of concrete with 30% replacement and 50% replacement of
Recycled concrete and broken / crushed glass were found to be good replacements for natural aggregates in concrete production, although the percentage by volume of recycled concrete and glass used ...
The compressive strength of concrete which contained 50 to 60% quarry dust in place of natural sand yielded higher strength compared to conventional concrete [37,38]. Published literature show wide-ranging studies on physical, mechanical characteristics and durability aspects of conventional concrete and self-compacting …
