Two different sands have been used in this study: the first one is a river sand (RS) (Fig. 1 a) from the river M'zi (around the city of Laghouat) and the second one is a crushed sand (CS) (Fig. 1 b) brought back from local quarry waste, near the city of Laghouat.Their particle size distributions are shown in Fig. 2.It should be noted that "CS" …
When river sand is used in concrete, the permeability of concrete is lower than river sand. It has 2 to 4% more water absorption. The water absorption of river sand is less than 1.5 to 3%. Concrete with M sand has less deceleration than river sand. The slope of river sand is higher than that of crushed sand. There are no marine products involved.

Compared to river sand, crushed sand is characterized with higher irregularity of fine aggregate with size 0.075–4.75 mm and rock powder content with size <0.075 mm, which makes it is difficult ...
The substitution of sand with quarry stone dust presents a cost-effective approach to construction. A comparative analysis is conducted against traditional concrete, demonstrating that utilizing quarry stone dust as a alternative for natural sand offers a compelling alternative that is not only economically viable but also environmentally sound …
M-sand is produced by crushing hard rocks and is a viable substitute for river sand. It possesses similar properties and is available in different gradations suitable for various construction applications. ... Crushed Stone Dust. Crushed stone dust, also known as quarry dust, is a byproduct of crushing stones in quarries. It can be used as a ...
impact of partial supplanting of river sand with crushed rock sand. Celik and Marar [6] reasoned that incomplete substitution up to 30% prompts decline in slump value. However, a critical improvement in the compressive, flexural strength and impact resistance was watched. A
Manufactured sand (M-Sand) is a substitute of river sand for concrete construction . Manufactured sand is produced from hard granite stone by crushing. The crushed sand is of cubical shape with grounded edges, …
Feasibility study on impact of replacement of river sand with crushed aggregate in concrete mix - ScienceDirect. Abstract. Section snippets. References (30) …
Manufactured Sand or Crushed Sand is the environmental-friendly solution that serves as a perfect substitute for the fast depleting and excessively mined river …
Semantic Scholar extracted view of "Effect of partial and total replacement of siliceous river sand with limestone crushed sand on the durability of mortars exposed to chemical solutions" by M. Bédérina et al. ... Abstract This article examines the effect of total substitution of siliceous sand by crushed limestone sand in mortar and concrete ...
Concrete samples were made by replacing river sand (RS) with desert sand (DS). Six mixes were made by replacing RS with DS by 0%, 10%, 25%, 50%, 75% and of the fine aggregate volume. Grade ...
At least four manufactured sand gradations from each crusher dust were produced and tested. Also the 0/4 mm fractions of the crusher dusts (unprocessed) were included for comparison. Sea dredged natural sand complying with BS EN 12620:2002 was used as the control fine aggregate. Table 2 shows the notation used in this paper for all …
substitution rate of river sand [18]. In addition to palm oil clinker, sugarcane bagasse ash is another organic material that could be used as a replacement of sand in concrete [19].
Three different levels of river sand substitution for crushed sand are examined, and the resulting concrete is evaluated for compressive strength, flexural strength, and ultrasonic pulse velocity ...
River sand material substitution is tested in laboratory based studies or using lifecycle assessment (LCA ... Potential primary sand sources crushed and round river concrete quartz sand and m-sand substitutes in form of rushed solid rocks: marble, amphibolite, granodiorite (a form of granite), and basalt (Figure source: Radek Kucera). ...

Dhon1 Dhulappa B. Borkar2 1,2 Department of Civil Engineering 1,2 Fabtech College of Engineering & Research, Sangola, Solapur, …
The gradation of crushed sand can be characterized by the fineness modulus, packing void fraction, and rock powder content, which should respectively be in the range of 41.8–45.0 %, 2.9–3.2 and 6–9 %. The correlation between the yield shear stress τ 0 of the mortar and its slump flow SF was obtained, which can be used to …
For this purpose, five mixtures of SCC with different limestone fines content as substitution of crushed sand (0, 5, 10, 15 and 20%) were prepared at constant water-to-cement ratio of 0.40 and 490 ...
As previously said, crushed sand has several properties such as greater durability, better strength, reduced segregation, and permeability, and it is proving to be cost-effective as a construction material in place of river sand. In a subsequent post, we will go over additional technical aspects of produced sand. Section Under Material.
River sand material substitution is tested in laboratory based studies [12] or using lifecycle assessment (LCA) research to reveal the technical and environmental challenges to …
Potential primary m-sand substitutes: Crushed solid rocks, particularly marble, amphibolite, granodiorite, basalt. Potential secondary m-sand substitutes: …
So it is a need of time to find some substitute for natural river sand. Against this background, concrete producers, construction engineers, builders and suppliers of sand are seriously thinking about crushed stone sand as a substitute for natural river sand. Crushed stone sand is not new to the construction industry. IS 383-1970 clearly ...
