Answer: setting of cement can be slowed
Notes: Gypsum is added to cement to slow down the setting process. This is crucial because it allows for better workability and prevents the cement from hardening too quickly, which can lead to cracks and structural weaknesses. Gypsum reacts with the tricalcium aluminate in cement to form ettringite, which helps regulate the hydration process. Without gypsum, cement can set in just a few minutes, making it difficult to work with.
