Green Design Interview Questions and Answers

Cable size determines its current rating, which is crucial for safe and efficient electrical installations.

• Cable size is typically measured in AWG (American Wire Gauge) or mm².

• The current rating of a cable depends on factors like conductor material, insulation type, and installation method.

• For example, a 12 AWG copper cable may have a current rating of 20 amps for general purpose circuits.

• It is important to select...read more

M20 design ratio is the ratio of the weight of cement to the weight of sand to the weight of coarse aggregates in concrete mix.

• M20 design ratio is commonly used in construction for concrete mix design.

• It specifies the proportions of cement, sand, and coarse aggregates in the mix.

• The design ratio for M20 is 1:1.5:3, which means 1 part cement, 1.5 parts sand, and 3 parts coarse aggregates by weight.

• This ratio ensure...read more

Slump test is used to measure the consistency of fresh concrete before it sets.

• It measures the workability of concrete.

• It helps to determine the water-cement ratio.

• It is a simple and quick test that can be performed on-site.

• The test involves filling a slump cone with concrete and measuring the slump.

• The slump value indicates the amount of deformation or settling of the concrete.

• The test is used to ensure that the ...read more

Nominal mix is a mix of fixed proportions of cement, sand, and aggregate. Design mix is a mix of specified proportions of cement, sand, and aggregate.

• Nominal mix is used for small construction projects where quality control is not a major concern.

• Design mix is used for large construction projects where quality control is important.

• Nominal mix has a fixed ratio of ingredients, usually 1:2:4 or 1:3:6.

• Design mix has ...read more
