Early strength is controlled by tricalcium silicate, C3S. Strength of cement developing after 7-8days of its placement is dependent on the amount of dicalcium silicate. LABORATORY TESTS FOR PORTLAND CEMENT. Fineness Test. Is done to verify the standard of grinding of cement. The rate of hydration of cement depends on its fineness. Fineness of cement is determined by sieve test. 100gms of cement is taken and sieved through. The residue left over the sieve should not be more than 10% of the original weight.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
