The diameter of steel refers to the width of a steel rod or pipe, while the weight of steel is determined by its density and volume.

• The diameter of steel is typically measured in inches or millimeters.

• The weight of steel can be calculated using the formula: weight = volume x density.

• For example, a steel rod with a diameter of 1 inch and a length of 1 foot will have a certain weight based on its density.

Mortar ratio and grade of concrete are crucial factors in construction projects.

• Mortar ratio refers to the proportion of cement, sand, and water in mortar mix.

• Grade of concrete indicates the strength of the concrete mix.

• Common mortar ratios include 1:3 (cement:sand) for general masonry work and 1:1 (cement:sand) for plastering.

• Concrete grades range from M10 to M80, with higher grades indicating higher strength.
