Study on the Gradation of Crushed Sand by Using a

2020-11-19 Since natural sand is largely replaced by crushed sand for industrial production, the quality of concrete is greatly affected by the gradation of crushed sand. Therefore, it is very important to measure the gradation of crushed sand. In this paper, the experimental sand with a particle size range of 0.15–4.75 mm is shown in Fig. 4. According to GB/T 14684-2011, the division of the size interval of the crushed sand

Research on shotcrete in mine using non-activated

2020-6-20 Singh (2016) proposed that the sand in concrete can be partly replaced by coal bottom, and the workability and strengths of concrete with different replacement levels were studied. Through these recycling approaches, the damage to the natural quality of the environment can also be mitigated by reducing the mining intensity of common raw materials used in concrete, i.e., quarries and sandpits (

What Is Crushed Sand? - Is It Good ? [Civil Planets]

2021-6-29 It can be suitable for concrete, filling material, etc., It can be used for concrete, plastering filler material, etc. Shape: The M sand is a cubical shape has a rough texture surface. The natural sand is round in shape smooth. Workability: Due to the cubical shape rough texture, little strain while mixing with other ingredients.

Coal bottom ash (CBA) is one of the by-products that can be employed as fine aggregate to replace natural sand in concrete. Owing to the very low water demand, roller-compacted concrete (RCC) has the potential to use CBA as fine aggregate at a high proportion. However, little research about RCC using CBA entirely as fine aggregate has been conducted.
