Calculate the sand equivalent using the following equation: Where: sand reading = height of sand in cylinder (mm) clay reading = height of clay in cylinder (mm) The sand equivalent value should be reported to the nearest higher whole number. For example, if the SE equation gives SE = 38.25, the reported SE should be 39.

Manufacturing sands requires crushing material into fine aggregate-ready particles. The crushing process creates uneven shapes and a larger concentration of microscopic particles, making manufactured sand stronger than the control mix made from natural sand [13]. Manufactured sand has higher compressive strength than natural sand.
The permeability of sand is an important factor in determining the movement and occurrence of liquids and gases in sand. The current work studied the influence of soil particle size and gradation on permeability by testing the permeability of different sand samples that consist of defined sand particles in certain ratios. The results of a total of …

1. Introduction. Additive Manufacturing (AM), also popularly known as 3D as per the NF ISO/ASTM 52900 standard, can be defined as; "the process of joining materials to make parts from 3D model data, usually layer upon layer, as opposed to subtractive manufacturing and formative manufacturing methodologies".AM …
1. Sand making. In crushed aggregates production, up to 30% (rock dependent) of materials acquired from the bedrock are reduced to sizes smaller than 4 mm, meaning they end up as waste. These stockpiles are a perfect feed for the production of manufactured sand. 2.
