Performance evaluation of cement mortar produced with manufactured sand ...
2021年8月23日 When river sand was replaced with manufactured sand, the fresh properties of mortar were significantly reduced than mortar with river sand [11], [12], [13]. However, it can be understood that mortar made with offshore sand showed improved fresh characteristics than river sand mortar, which however lowered the mechanical
I-sand: An environment friendly alternative to river sand in
2016年10月30日 But there is a shortage of natural river sand resources [1,2], and there is an urgent need to find a new material to replace natural river sand [3–6] to make up for the resource gap. The Yellow River Bay Area Base is located in the area near the Mawusu Desert, with a large number of desert sand resources.
Replacement of Sand in Concrete for Sustainable Building
River sand is one of the primary materials used in manufacturing concrete. ... Quarry dust can be partially used as an alternative to river sand, as fine aggregate in concrete production. It is basically a by-product of stone crushers produced during the crushing and screening process of coarse aggregates.

2021年8月23日 1. Introduction. Mortar is the highest consumed cement-based composite material next to concrete in construction activities, which enables the substantial requirement of sand than concrete [1], [2].The research problem was identified with the construction industries who face difficulties in obtaining good quality fine aggregate not
Is River Sand Good for Gardening? All the Facts (+7 Alternatives)
7. Coconut Coir. Coconut coir is a fibrous material harvested from the outer husk of a coconut. You can use coconut coir to supplement heavy clay soils and areas with too much sand. Like many river sand alternatives, coconut coir simultaneously improves soil drainage and water retention.
Feasibility study on impact of replacement of river sand with
2023年8月26日 The majority of studies on using crushed sand as an alternative for some sand of river in concrete focuses on concrete grades up to M40. However, there is a dearth of material on HPC using higher grade concrete. This study delves into the utilization of crushed aggregate to supplant river sand, building upon the groundwork laid by prior ...
Sustainable replacement materials for concrete production from ...
2022年7月2日 Ecological resources are constantly consumed to produce concrete, resulting in environmental damage. This is also one of the issues for environmental sustainability. This study discovers a replacement material of river sand and stone aggregates produced from sustainable utilization of renewables to save the environment.
Materials Free Full-Text Recycling of Periwinkle Shell Waste as ...
2023年2月24日 This study investigated the suitability of using crushed periwinkle shell (CPWS) as a reliable constituent material for sand and stone dust in producing hollow sandcrete blocks. The CPWS was used to partially substitute river sand and stone dust at 5, 10, 15 and 20% in sandcrete block mixes using a constant water–cement ratio (w/c) of
Replacement of Natural Sand with Efficient Alternatives: Recent ...
increased need to find new alternative materials to replace river sand so that excess river erosion is prevented and high strength concrete is obtained at lower cost. Partial or full replacement of natural sand by the other alternative materials like quarry dust, foundry sand and others are being researched from past two decades, in
Impact on Replacement of Natural Sand with Artificial Sand
2023年3月6日 Artificial sand has a potential to provide alternatives to natural sand and helps in maintaining the environment as well as economical balance.
