At NGLC Realtech, our civil engineers give attention to
every minute details. Therefore, we do series of test on our
construction site before starting the construction. One such test is
sand-silt test. We do sand testing to determine if the foundry sand has
the correct properties for a certain casting process or not. There is a
probability that the sand sample consists of unwanted particles of silt,
clay or other fine dust that may affect our sand sample. The amount of
silt content in the sand should not exceed more than 8%. This is because
the silt shrinks and expands due to the weather conditions which affects
the strength of the structure. Therefore, we ensure that the sand we use
for concrete mixture is of premium quality.
