“…This paper is an extension of work originally presented in conference IEEE 5th International Conference on Engineering Technologies & Applied Sciences, 22-23 Nov 2018, Bangkok Thailand [1]. In the world, fine aggregate, probably natural sand, composes up to 30% of the volume of concrete, it is around 4 billion tons sand is required to meet annual necessity of concrete production [2].…”

This, research work was to study the potential of M-sand as compared to river sand in concrete, here M-sand is replaced by river sand 0%,45%,50%,55% and 100% in the concrete mix, Mix design is designed as per IS Standards. In this research a mix 1:2.32:2.82 (M20) was considered. The test specimen was casted for 7days, 28 days and 90days. The performance of M-sand was determined by several experiments such as slump test, impact strength test, flexural Strength, and compressive strength test. The results attained from each test states that as M-sand increases the slump value decreases. flexural strength, compressive strength and impact test of concrete at 7 days, 28 days and 90 days is greater at 100% and 50% replacement of M sand by river sand.

“…The American standard ASTM C 33 [116] accepts only up to a limit of 7% of fine material passing through the 150 µm sieve, and NBR 7211/2022 [117] accepts between 10% and 12%, maximum, (for concrete subjected to surface wear and for concrete protected from surface wear, respectively). Some authors [86,89,97,100,118] showed that the average percentage of retention on the sieve following 150 µm/75 µm varied from 5.5% to 8.5%.…”

“…3.2.1. Workability Despite the variation in the effect of stone dust on concrete workability due to the different physical characteristics of SD found in the various mining companies around the globe, such as angularity, fineness modulus, morphology, specific surface area, and specific mass, most of the research results [8,87,90,[94][95][96]100,[102][103][104][107][108][109][110]121] conclude that the higher the level of substitution of stone dust, the higher the content of fines and thus the greater specific surface area, leading to lower workability of concrete in the fresh state. Also, according to data from these publications, the workability of fresh concrete made with stone dust replacing natural sand as fine aggregate suffers a reduction in comparison with reference concrete (with 0% replacement).…”

The escalating demand for natural resources within the construction industry is progressing upward. At the same time, however, there is a great concern regarding the depletion of these resources. This review paper emphasizes the significance of utilizing alternative aggregate materials in concrete. Particularly, it aims to explore replacing natural sand with stone dust. On the one hand, the depletion of primary sources of natural sand worldwide, combined with environmental and ecological concerns, drives the adoption of alternative aggregate materials for sustainable concrete construction. On the other hand, stone dust, a waste from the quarrying industry, offers a cost-effective and practical solution for producing concrete. This article presents a comprehensive literature review of the main trends in utilizing stone dust in recycled aggregates in the past decade and its influence on concrete properties. It addresses critical research questions regarding the physical and chemical properties of stone dust aggregates compared to natural sand; the impact of stone dust on the workability, mechanical, physical, and durability properties of recycled concrete; and the potential reduction of environmental impacts in terms of energy consumption and emissions through the replacement of natural sand with stone dust. Ultimately, this paper proposes future investigative work based on identified research gaps.

“…The scarcity or insufficient supply of excellent quality sand has resulted in a significant price increase, which has an impact on building costs [1]. This motivated academics and experts in the construction industry to search for a suitable material that is acceptable to the environment and can be effectively used in construction practices as an alternative material while reducing production costs [2]. However, one possible alternative material is manufactured sand.…”

Due to the increasing demand for sand for construction activities across the world including Mogadishu Somalia, natural sand resources are growingly used up and its price is becoming increasingly high. This study aimed to research the influence of Mogadishu-manufactured sand on the engineering properties of concrete. Manufactured sand refers to fine aggregate which is less than 4.75mm. In this research, Mogadishu Manufactured sand was refined from the crushed limestone rock as a replacement for river sand. The overall objective of the study was to evaluate the influence of Mogadishu manufactured sand on the engineering properties of concrete; the specific objectives were to examine the properties of plastic and hardened concrete; to investigate the durability of concrete with Mogadishu manufactured sand. The study used manufactured sand in incomplete or complete replacement for natural sand. The basic aggregate tests considered were sieve analysis for fine and coarse aggregate, specific gravity, and water absorption was also done. Design mix of class 30 concrete having mix amount for both natural and manufactured sand was considered for the workability test (slump test and compaction factor test). The splitting tensile strength test and compressive strength test for 28 and 56 days was done. The study, in addition, considered durability testing by exposing the concrete to sodium chloride, magnesium sulphate, and sulphuric acid. Then final assessment was done to determine how these chemicals affected the concrete after 28 and 56 days of immersion. It was found that the slump and compaction factor values of the concrete mix with Mogadishu manufactured sand decreased compared to that of conventional concrete. Concrete with Mogadishu manufactured sand significantly improves the strength properties of the concrete up to 25% replacement and reduces as replacement increases. This was attributed to the presence of micro fines in the Mogadishu manufactured sand generated from limestone rock. When exposed to sulphuric acid, magnesium sulphate, and sodium chloride, the durability of concrete with manufactured sand were improved as compared to that of normal concrete with river sand. Hence from the experimental investigations, it is concluded that Mogadishu manufactured sand can be partially utilized as fine aggregate in concrete production of construction activities.
