Concrete and Cement are the most widely used building materials in the construction industry for over 100 years. Over the years, this construction material has been enhanced and developed to fit to the usage and requirements at site. Several researches are happening around this topic to increase the durability, strength and performance of this building material.
Setting Time Cement paste setting time is affected by a number of items including: cement fineness, water-cement ratio, chemical content (especially gypsum content) and admixtures. For construction purposes, the initial set must not be too soon and the final set must not be too late.
1- Water/cement (w/c) ratio - The setting time of cement increase with the increase of w/c ratio. 2-Temperature and relative humidity -The setting time of cement decreases with a rise in temperature and decrease of relative humidity. 3- Fineness of cement - The setting time of cement decreases with a rise in fineness of cement.
