The grade of cement is determined by testing cement mortar of proportion of cement to sand: Q. The proper size of mould for testing compressive strength of cement is. Q. 5 kgs of cement was mixed with 2 kgs of Sand. If the quantity of sand is tripled and that of cement is doubled, find the new ratio between cement and sand.
The setting time of cement mortar can vary depending on factors such as the type of cement used, the water-to-cement ratio, the temperature and humidity of the environment, and the presence of any additives or admixtures in the mix.. Normally, the initial setting time for cement mortar is around 30 minutes to 1 hour, while the final setting time is around 6 to 8 hours.
