b) Discoloration
c) Burns or skin ulcers
d) Tingling sensation

Answer 1

Wet concrete or mortar can cause burns or skin ulcers if trapped against the skin.

Step-by-step explanation:

When wet concrete or mortar comes into contact with the skin, it may cause caustic burns or skin ulcers due to its abrasive and alkaline nature. Since concrete is a mixture of lime mortar, sand, pebbles, and water, it can cause injuries to the skin when it hardens, and the high pH can result in a chemical burn. Additionally, if wet concrete gets trapped against the skin for an extended period, it can lead to severe burns that might require medical attention.
