Standard deviation is a measure of the amount of variation or dispersion of a set of values.

• Standard deviation is calculated by taking the square root of the variance.

• It is used to quantify the amount of variation or dispersion of a set of values.

• Higher standard deviation indicates more spread out data points, while lower standard deviation indicates data points are closer to the mean.

• It is commonly used in quality con...read more

To clear NCR, identify root cause, implement corrective actions, verify effectiveness, and close out the NCR.

• Identify the root cause of the non-conformance.

• Implement corrective actions to address the root cause.

• Verify the effectiveness of the corrective actions through testing or inspection.

• Close out the NCR once the corrective actions have been successful.

• Document all steps taken in the NCR clearance process.

Testing procedure for coarse aggregate involves determining its physical properties and quality through various tests.

• Conduct sieve analysis to determine particle size distribution

• Perform specific gravity and absorption test to assess porosity

• Check for shape, surface texture, and angularity through visual inspection

• Test for resistance to abrasion and impact to evaluate durability

Silt content limit as per IS code is 3% for fine aggregate.

• Silt content limit for fine aggregate as per IS code is 3%.

• Excessive silt content can affect the quality of concrete.

• Silt content can be determined by conducting a sieve analysis test.
