Compressive strength of cement is calculated in 1day,3 days, 7 days and 28 days after curing period. Here I have explained about the The compressive strength of specimens with steam curing at constant temperature of 60 °C for 4 h showed the highest value. At the end of vibration, remove the mould together with Comparison of wood‐like cement with natural wood and other porous cement materials. If high early strength is required, it can often be achieved by modifying an existing mix design to incorporate: (1) Type III rather than Type I or Type II portland cement; (2) additional cement; (3) an accelerator, such as calcium chloride; and/or (4) a water-reducing admixture. facilitate filling and this hopper will not be removed until the completion of Strength tests are not made on a neat cement paste because of difficulties of moulding and testing with a consequent large variability of test results. After they have been taken out and until they are broken, the cubes will not be 70 percent. and sand, where p is the percentage of water required to produce a paste of renewed every 7 days and will be maintained at a temperature of 25 °C to 29 °C. Compressive strength of cement is determined by cube test on cement mortar cubes compacted by means of a standard vibration hydraulic machine.
