10+ Material Engineer Interview Questions and Answers

If temperature of DBM or BC is not achieved at the time of laying, the material should be reheated.

• Reheat the material to achieve the required temperature before laying

• Ensure that the temperature is monitored and maintained during the laying process

• Consult with the manufacturer or supplier for specific instructions on temperature requirements

Add water to increase the slump of concrete.

• Add small amounts of water and mix thoroughly.

• Check the slump again and repeat if necessary.

• Avoid adding too much water as it can weaken the concrete.
