The tar sand used in this study was obtained from the Wadi Issal area of Jordan. The collected sample was crushed using a jaw crusher and then sieved, according to British Standard BS 1796–1, into the following size fractions: < 106, 106–212, and 212–425 μm.Total organic carbon (TOC), inorganic carbon (IC) and the calorific value (CV) were determined for …
Rahman et al. [30] first replaced the e in Hardin's relation (Eqs. (1), (2)) of clean sands by the e* to predict the G max of sand with fines. Then, Goudarzy et al. [12] used the same concept to predict G max for Hostun sand with fines. Therefore, the applicability of e* is only briefly described for the sake of completeness and the focus of the current article was …
On the other hand, River sand being the majorly convenient source for fine aggregate worldwide, is exploited haphazardously at an annual rate of 750 MT [3], [4] for construction activities. Fine aggregates occupy 30–35% of concrete and control its rheological and mechanical characteristics significantly [5].Many researchers have critically analysed the …
A method was developed to estimate the power requirements of a lab-scale jaw crusher. The impact of material properties on the crusher performance is studied. Eight concrete strength classes (C20/25–C80/95) were considered in the approach. ... respectively. As aggregates, river sand and gravel were used with a density of 2.65 g/cm 3 ...
The global consumption of natural sand is very high, due to the extensive use of concrete or mortar. The fine and coarse aggregates generally occupy 60% to 75% concrete volume (70% to 85% by mass ...
Crushed sand fines have a pronounced effect on fresh concrete rheological properties, which can be controlled through a concrete micro-proportioning approach, i.e. optimisation of the particle size distribution (PSD) in the very fine range of the grading (⩽250 μm).The paper describes a study where possibilities of producing crushed sand by combining …
M-Sand is extracted from a specific hard rock (granite) utilizing cutting-edge international technology, resulting in the needed sand property. Disadvantages of Crushed Sand: The angular grain or flaky particles produced by poor crushing may necessitate more water and cement, rendering it unsuitable for concrete production.
It is shown that physical and chemical characteristics of tailings are comparable to crusher sand used in engineering construction and therefore, tailings can be used to partially replace sand in ...
