To substitute river sand, the concrete mix M4 (51% beach sand + 49% quarry powder) was discovered to be the best. It has a compressive durability t of 39.7 ± 0.20 MPaf. Quarry powder has been shown to boost the compressive durability of concrete. Mix M4 has split tensile durability of 3.9 ± 0.15 MPa and flexural durability of …
Concrete is a composite building material made from a combination of aggregate and cement. The limitation of concrete material, in this case, is a fine aggregate (river sand).
In this study the properties of concrete with quarry dust as fine aggregate is studied to find out its suitability to replace river sand in structural concrete. Furthermore, use of fly ash with 30% of cement replaced by fly ash is explored as means of increasing the performance of the quarry dust mixes.
This study investigates the suitability of laterite as sole fine aggregate in place of sand, and specifically seeks to determine whether laterized concrete would satisfy the minimum compressive ...
of concrete with river sand. Table 2: Characteristics of concrete using Manufactured Sand and River sand Bond strength: The bond between rebar and the concrete was examined by conducting pull out test. The pull out test was performed using 12 mm HYSD bar for M20 concrete as per IS 2770 code guidelines. The bond strength at failure

Regarding building and construction, it is essential to understand the differences between the two most common types of Sand – M sand and river sand. Both have unique properties that make them ideal for different uses. In this article, we explore the differences between M sand and river sand in detail, including the advantages and uses of each.
Types of Sand & Classification of Sand. Followings are the classification of Sand: Based on the grain size of the particle, sand is classified as Fine Sand(0.075 to 0.425mm), Medium Sand(0.425 to 2mm), and Coarse Sand(2.0 mm to 4.75mm) Based on origin, sand is classified as Pit sand, River sand, Sea sand, and manufactured sand.
