Answer: a) gypsum
Explanation:
The setting and hardening time refers to the time taken by the concrete to dry.
The admixtures are added to the concrete to modify their properties and it is also used while mixing and transporting a mixture.
Gypsum is a soft mineral which is composed of calcium and sulfate. It is used as fertilizer and used in sculpture in the form of alabaster. It is always found with sedimentary rocks. Since, it is a soft mineral, when it mixed well with concrete, we can increase the hardening time of it.
