Testing of Sand Quality at Construction Site for Concrete
Sand with a high clay content is not suitable for construction as it can cause cracking and shrinkage in concrete. The clay content of sand can be determined by conducting a hydrometer analysis, where a soil suspension is analyzed for specific gravity and particle size. The clay content is then calculated using a formula based on these values. 5.
