What is Sand?
Sand is a material obtained naturally from locations like rivers, seas, beaches, and deserts. Sand is a type of granular substance made up of tiny fragments of rock and minerals. It forms through weathering, erosion, and the breakdown of larger rocks over time. The size of sands typically falls within the range of 0.0625 to 3 millimeters in diameter. The composition of sand depends on its source. Due to mineral variations, the color of sand can be white, yellow, brown, and even black.
Sand is found in various environments, such as beaches, deserts, and riverbanks. It plays an important role in the construction sector including shaping landscapes and ecosystems.
How to know good quality sand?
Grain Shape – Good sand grains should be well-rounded and have a smooth surface. Fine sand is good for mortar and plaster. Medium coarse sand is ideal for concrete. Consider the specific application when choosing grain size. Sand Price in Bangladesh depends on different grain shaped.
Color – The color of good quality sands should be consistent and free from excessive dark patches or staining.
Particle Size – The sand should have a consistent particle size distribution. Ideally, it should contain fine, medium, and coarse particles. It allows for better packing and reduces the chances of segregation.
Strength – For high-strength structural purposes, the strength of sand is very important. Choose sand with a fineness modulus (FM) between 2.5 and 2.8.
Texture – Rub the sand between your fingers. It should feel gritty and not sticky. Clay or excessive moisture will make it stick.
Cleanliness – Look for minimal presence of clay, organic matter, or debris like wood chips or pebbles.
Appropriate Moisture – The sand shouldn’t be overly wet or dry. Slightly damp sand (clumping together slightly) is ideal for most uses.
Chemical Reaction – Sand should be chemically inert, meaning it does not react with the materials it comes into contact with. It is particularly important in applications where sand is used as a base for concrete or as a component in chemical processes.
Availability – Good quality sand should be readily available and accessible from reliable sources. It ensures a consistent supply and reduces the chances of delays in construction or other projects.
