What is initial setting time of cement

Question

Accepted Answer

Initial setting time of cement is the time taken for the cement paste to harden sufficiently to resist certain specified pressure.

Initial setting time is an important property of cement as it determines the time available for mixing, placing, and finishing of concrete.
It is measured by the Vicat apparatus, which consists of a needle and a mould filled with cement paste.
The initial setting time is typically around 30 minutes to 1 hour for most types of cement.
Different types of cement may have different initial setting times due to variations in composition and additives.
For example, rapid-setting cement has a shorter initial setting time, usually around 5 to 15 minutes.
The initial setting time can be influenced by factors such as temperature, water-cement ratio, and the presence of accelerators or retarders.
It is important to monitor and control the initial setting time to ensure proper workability and strength development of concrete.
