12 sie 2020 · Standard Value of Specific Gravity of Cement:- The value for specific gravity of Ordinary Portland Cement (OPC) is nearly 3.15 while the specific gravity value of Portland-Blast-Furnace-Slag and Portland-Pozzolan cements is nearly 2.90.
10 cze 2024 · The specific gravity of cement can be determined using methods such as the specific gravity bottle method or the Le Chatelier specific gravity flask method. These involve measuring the mass or volume of cement and a reference liquid, usually kerosene or water, and calculating the specific gravity accordingly.
2. ^ecific gravity of chert— the chert from each of the six sources was separated into three groups based on bulk specific gravity (saturated surface-dry basis). The specific gravity ranges selected for these groups were 2.55 plus, 2.45-2.55, and 2.45
21 paź 2024 · The standard value of the specific gravity of ordinary Portland cement is around 3.15 g/cc. However, this value may differ slightly for different types of cement. For example, Portland-blast-furnace-slag cement and Portland-pozzolan cement have specific gravities closer to 2.90 g/cc.
24 maj 2022 · Use of aggregates with low specific gravity such as shale, sandstone and chert can produce poor performance in concrete , however, natural or synthetic lightweight aggregates have been successfully used to produce high quality concrete.
A value of specific gravity of cement greater than 3.19 shows that the cement was not properly minced into fine powder during its production or the cement has more moisture content. The presence of moisture content in cement is easily identified by the presence of chunks in cement.
