What Is Bulking Of Sand? And Its Importance [Civil Planets]

Why is it important to find bulking of sand? Up to the M25 grade of concrete, we make nominal mixes by volumetric measurement. In the design mix, we weigh the materials. If the moisture is present in the sand, then it makes the sand look bulkier, which could result in inadequate sand proportion in the concrete ratio. For Example, If we need to add 1m 3 sand in the concrete mix ratio, we take 1

What is Bulking of Sand? Significance & Test Steps

Sand bulking relies on the sand’s humidity. But when the temperature is raised by introducing more heat, the sand particles are pressed next to each other as the film around the sand particles cracks and the sand bulking is decreased. Dry sand and the water-filled sending will have the same size. This definition is used to evaluate the amount of sand bulking in the test.
