Masonry sand is a much finer and more uniform type of sand that has very small grains. As such, masonry sands have the ability to create a smooth, finished surface when used in mortar and concrete mixes. Concrete sand has larger grains that are much coarser than masonry sand. The larger grains are what give concrete mixes added …
In contrast, Parasha et al. used WFS as a partial alternative for natural river sand in concrete in proportions of 0, 10, 20, 30, and 40%. Results indicate that concrete compressive strength is decreased when WFS is substituted. Its fine and porous nature accounts for the decrease of compressive capacity when (WFS) is included. (WFS) …
Concrete is the most used material after water. Concrete is made of cementing material, coarse aggregate, fine aggregate and water. The coarse and fine aggregates make about 70% of concrete. Till present natural river sand was the only material that was used as fine aggregate, but as it is a natural resource, it is limited.
The use of natural river sand is increasing as the construction industry continues to grow. The construction sectors projects was halted in half due to unavailability of natural river …
Courtesy: connect2india. Pit sand is a type of sand that comes from pits or mines, which are natural places where sand is found. It is often used in building projects and civil engineering work. Compared to other types of sand, like river or beach sand, pit sand is usually more coarse.
River sand, also known as natural sand, is a vital material used in various construction applications. Its unique properties make it a preferred choice for builders …
The paper presents results of study on concrete using quarry dust to replace sand at levels of 0%, 25%, and by weight. Design mixes were prepared to achieve concrete grades C25, C30, C35, C40 ...
Crushed rock sand has surfaced as a viable alternative to Natural River sand and is being now used commonly throughout the world as fine aggregate in concrete. It is manufactured by crushing the quarried stone to a size that will completely pass through 4.75 mm sieve.
Stone dust is a waste material obtained from crusher plants. It has potential to be used as partial replacement of natural river sand in concrete. Use of stone dust in concrete not only improve ...
River sand is a loose, fragmented natural material that is made up of tiny particles of decomposed shells, corals, or rocks. It is an essential raw material in the construction industry, adding strength and sustainability to buildings. River sand is commonly used in the concrete mix. With a lower clay and silt content in river sand, …
The increasing annual emissions of iron ore tailings have proved a great threat to the natural environment, and the shortage of natural river sand, as well as the pursuit of sustainable development materials, provides motivation to reuse iron ore tailings as a fine aggregate in concrete. Due to the …
The concrete consists of major component which are available in natural form. River sand is a resource which is a very limited source, so the conservation of it is very important. Stone dust is the alternative material to natural sand and it can be used as resource for construction as it possesses the properties closer to natural sand.
Also called natural sand, river sand is categorized as fine sand and is usually found near streams and river banks. The softness of river sand allows for its …
River Sand: Extracted from riverbeds, river sand is a common natural fine aggregate. It is often well-rounded and has a variety of particle sizes. However, indiscriminate sand mining from rivers can lead to environmental concerns and ecological imbalances. ... Coarse sand is often used in concrete for its ability to provide bulk and …

WFS can be used up to 30% substitution instead of natural river sand with no harmful influence on concrete strength. This is owing to the micro filling which provides more dense concrete, leading to more resistance to load. However, a decrease in strength was observed at a higher dose of WFS (beyond 50%).
