2015-2-4 In other words, crushed sand cannot be sold in the same way as crushed coarse aggregate, i.e. by sending a price offer and description of properties to a potential customer. In the author’s perception, crushed sand needs a much more technical kind of
Environmental considerations cause pressure on concrete producers to reduce their use of natural sand. The availability of sand is also reducing and in many countries, authorities have put restrictions on the use of natural sand. Crushed rock and waste aggregate tend to have less rounded edges and corners resulting in poorer flow of fresh mortar.
2019-5-23 concrete when river sand was replaced by crushed sand and up to which extent replacement of river sand is significant in accordance with standards and observed that beyond 70% replacement of river sand compressive strength is not increased and slump value crosses the specified control limit.
2016-3-3 materials to replace sand. This study aimed to investigate the suitability of using crushed brick in concrete. Crushed brick originated from demolished masonry was crushed in the laboratory and added partial sand replacement. Three replacement levels, 15%,20% and 25%, were compared with the control.
2020-11-28 The research covered determining the effects of natural sand replacement with manufactured sand of C-25 concrete properties. This experimental study only limited to 0%, 10%, 20%, 40%, 60% and 100% of replacement. In this experimental study, only some engineering properties of aggregates, slump
2016-2-25 crushed cockle shell content as partial sand replacement. The use of crushed cockle shell as partial sand replacement in plain concrete was based on a simple approach viz. by direct replacement by weight of total fine aggregate content. The sand replacement is varied from 5% to 25% with 5% interval leading to the formulation
Wastes are indispensable part of human existence. In 2017 in Poland, as much as 90.5% (113.8 million Mg) of all wastes were those related to economic activity. Already for years, the largest group of industrial waste are those from the mining, energy and metallurgical industries. Numerous scientific studies have shown possibilities of using metallurgical waste for the production of concrete
2015-10-30 The use of crushed rock sand as a partial replacement of river sand in concrete production was and 0.59 for 0 % to 100 % natural sand replacement. The slump ranged between 49 and 60 mm for 0 % to 100 % natural sand replacement. N/mm2. The effective natural sand (RS) replacement ranged between 0 and 60 % with the best results achieved at 20 %
2019-9-18 The use of sludge as a sand replacement has increased the permeability of concrete to the greatest extent. The use of rounded aggregate from recycled concrete mix also but to a lesser extent, and the use of crushed recycled concrete aggregate from did not affect the permeability of concrete.

2020-7-1 One of the solutions is to use crushed sand to replace natural sand as aggregate in concrete, especially the study of using crushed sand to make high-strength self-compacting concrete. Crushed sand is an aggregate of angular shape and surface roughness that hinders the self-compacting of the concrete mixtures.
