![]() IS code – The test should be conducted as per IS code 4031 Part 1, and the test sample should be collected as per IS code 3535. It is measured by the ratio between coarse particles (which retained in 90- micron sieve analysis) to the fineness particles (which passed through the sieve analysis). Final Setting Time of Ordinary Portland Cement is 600 minutes. The initial setting time should not be less than 30 minutes. Initial Setting Time of Ordinary Portland Cement is 30 minutes. DENSITY OF PORTLAND CEMENT CONCRETE LAB DATA SHEET T65. The fineness of cement is determined by the sieving method. Specific Gravity of Ordinary Portland Cement is 3.15. This protocol covers the determination of the specific gravity, density, percent absorption and. More fineness means high concrete workability and thus increases the setting time.The fine particles are easily mixed with the water to make the cement paste as compared to the coarser cement particle.Fineness cement can easily blend with other ingredients.When combined with water, cement forms a paste that. ![]() Cement acts as the binding agent or glue in concrete. Cement typically accounts for 10 to 12 of the concrete mixture.
