While we are calculating cement for mix design we consider the specific gravity of cement as standard 3.14. So, any change in cement specific gravity will affect the mix design. Hence, it is essential to test the specific gravity of the cement procured before the mixing process. This is the main reason behind we reject the old stored cement.

Standard Value of Specific Gravity of Cement. The specific gravity value of portland cement is generally around 3.15 while the specific gravity value of portland-blast-furnace-slag and portland-pozzolan cements may have specific gravities near 2.90. Portland Cement Association (PCA). (1988). Design and Control of Concrete Mixtures.

As per industry, the acceptable value of specific gravity of cement is up to 3.19. But if the value is greater than 3.19 it means cement is containing greater amount of moisture content which will affect the workability and strength of concrete. This is why we need to calculate the correct value of specific gravity of cement before using it in ...

Jul 08, 2020· Example: Determine how much hematite, lb/sk of cement, would be required to increase the density of Class H cement to 17.5 lb/gal: Water requirement of cement = 4.3 gal/sk. Water requirement of additive (hematite) = 0.34 gal/sk Specific gravity of cement = 3.14. Specific gravity of additive (hematite) = 5.02

What is the specific gravity of cement? Specific Gravity of Cement is nothing but the ratio between the volume of cement to the volume of the same quantity of water. Usually, the value lies between 3.10 – 3.16 g/cc. Some types of cement such as PPC, Portland Blast furnace slag will have the value near 2.90.. In simple, Cement is 3.10 times heavier than the water.

20 8-7-8 � 83; Ordinary Portland cement of 43 grade of Ultra-tech Cement confirming to IS: 8 2- 98954 standards was used. The specific gravity, normal consistency, initial and final setting times and compressive strength of cement tests had been carried out and the results are presented in Table 3.2. Table: 3.2 Test results of cement

This specific gravity of cement ranging from 3.1 to 3.16 g/cc.By this statement, we may ensure that cement 3.1-3.16 times heavier than this water of this same volume, and it sinks in water.. Because the specific gravity isn't less than 1, every material consists of so many little pores, which can contain voids in it, and the material becomes useless when any void present in the material.

As we know that the specific gravity of ordinary portland cement is between 3.1 to 3.15 g/cc and for portland pozzolana cement and portland blast furnace cement it is near to 2.90 ( As per Portland Cement Association -PCA 1998). What is specific gravity? The specific gravity of any substance may be defined as the ratio of its specific weight of given volume to that of a standard substance of ...

•Bulk specific gravity (SSD): Used to determine the "solid volume" (absolute volume) of a material going into concrete It is determined b yygg submerging the material in water for 24 hours in order to fill any permeable voids 6 Specific Gravity Water: Specific Gravity = 1.00 Stone: Specific Gravity = 2.70 Same Volume, but 2.70 Times More Mass

To determine the unit weight of a substance like cement, multiply the specific gravity of the cement by the unit weight of water. gcement = 3.15 x 62.4 lb/cu ft = 196.56 lb/cu ft Bulk specific gravity of concrete materials Portland Cement 3.15 Pozzolan 2.2 to 2.8 Natural Aggregates 2.4 to 2.9 Water 1.0

If the cement has exposed to extreme moisture content then, the specific gravity of cement will differ because of the moisture content present in the pores. Every material has solid particles and pores which may contain water in it. Normally our nominal mix design is based on the value of specific gravity of cement as 3.15. The value will ...
