MLE Interview Questions and Answers

Steel bars are used as reinforcement in concrete structures to increase their strength and durability.

• Steel bars are commonly used in construction of buildings, bridges, and other structures.

• They are placed in concrete to provide tensile strength and prevent cracking.

• The size and spacing of steel bars depend on the design and load requirements of the structure.

• Steel bars are also used in precast concrete elements such as beams and columns.

• Proper placement and installation of ...read more

Slump and cube tests are used to measure the workability and compressive strength of concrete respectively.

• Slump test measures the consistency and workability of fresh concrete.

• Cube test measures the compressive strength of hardened concrete.

• Slump test involves filling a slump cone with concrete and measuring the slump of the concrete after the cone is removed.

• Cube test involves casting concrete cubes and testing them for compressive strength after a certain period of time.

• Bo...read more

Grading and ratio of cement are important factors in determining the strength and durability of concrete.

• Grading refers to the size distribution of the aggregates used in the concrete mix.

• The ratio of cement to aggregates affects the workability and strength of the concrete.

• A higher ratio of cement to aggregates results in stronger concrete, but may also make it less workable.

• The appropriate grading and ratio of cement depend on the specific application and environmental cond...read more

Pearson correlation measures the strength and direction of the linear relationship between two variables.

• Pearson correlation ranges from -1 to 1, where 1 indicates a perfect positive linear relationship, -1 indicates a perfect negative linear relationship, and 0 indicates no linear relationship.

• It is calculated by dividing the covariance of the two variables by the product of their standard deviations.

• For example, if the Pearson correlation coefficient between height and weig...read more
