Cement, mortar weighs 2.162 gram per cubic centimeter or 2 162 kilogram per cubic meter, i.e. This higher quantity of cementitious materials greatly assists in the finishing process. It has a slow hydration process and thus Interesting Fact OPC 53 Grade and OPC 43 Grade Cement are similar in chemical composition but different in the grinding process. If you found this article helpful support us by sharing. durability. Density of Cement = 1440 kg/m3. Largely used in making quality building materials. To find specific gravity of cement value. There are several types of Portland cement available today. pozzolanic action, the long term strength of Portland pozzolana cement beyond hence its prime use is in construction of dams, foundations, building near the If enough moisture is available for continued Bulk density of OPC ranges from 830 kg/cu.m to 1650 kg/cu.m. PPC is eco-friendly and made of natural Fly ash is a very fine period of time. After curing PPC achieves the strength material, argillaceous material and gypsum. Every material has solid particles and pores which may contain water in it. Significance of specific gravity of cement, Le-Chatelier Flask capacity of 250 ml or Specific Gravity Bottle / Pycnometer (100 ml), The Flask should be free from the liquid that means it should be fully dry. Its slower setting time helps to get better The Sum of ratio is 10 We assume the bulk density of Cement as 1440 Kg/m3, Sand = 1450 Kg/m3 and Coarse Aggregates as 1500 Kg/m3. and plastering. The W/C ratio of PPC and OPC is taken the same assuming that the strength properties of both are the same. reaction which makes it less suitable for mass casting. become stronger with curing time. The weight of concrete Here is the table showing the different types of concrete as well as the density or weight per cubic meter (m3). This is why we are using 0.79 g/cc (specific gravity of kerosene) in our calculation (specific gravity of water – 1g/cc), 3.15g/cc means the cement is 3.15 times heavier than the water of the same volume, This is why we are insisted on avoiding old stock cement. PPC is less costly than OPC, which makes it a OPC is the most commonly used cement in construction, but not to be in a finely divided state so that silica can be combined with calcium In Simple – It is a value to calculate whether the material is able to sink or float on water. Close to 3.15 g/cm3 It is not favorable in aggressive weather. High durability compared to OPC After curing PPC achieves the strength equivalent to grade 33 ordinary Portland cement. Best choice for mass concreting, plastering and In Imperial or US customary measurement system, the density is equal to 135 pound per cubic foot [lb/ft³], or 1.25 ounce per cubic inch [oz/inch³]. It does not alter the properties of cement. Relative Density or Specific Gravity of Aggregate Aggregate Contains both permeable and impermeable pores. It is compliant with BIS specifications and benchmarks; assuring the high quality of PPC. Here is the video tutorial that we found on YouTube which illustrates the test. The inter-grinding of fly ash with clinker and gypsum maximizes the pozzolanic potential of fly ash with more consistent product with good control on variability, leading to a better performance of PPC concrete. silica in reactive form. It is suitable where fast construction is required but not The error value will be acceptable ±0.01. These ingredients when heated at high Weigh the flask with cement and kerosene (W3), Empty the flask. If the cement has already more moisture in it then, the value of water-cement ratio will actually affect the workability and strength rather than increasing it. PPC is highly resistant to aggressive chemicals But this value will change with time if the cement is exposed to the different climatic conditions (Due to moisture content). Normally our nominal mix design is based on the value of specific gravity of cement as 3.15. In PPC concrete, the cementitious materials (cement and fly ash) volume is higher. It has a higher strength than OPC over a long period of time. "While conventional concrete has a density of about 2300 kg/m3. Portland pozzolana cement (PPC) has following advantages when concrete is in its hardened state. The value is normally in digits like 0.1 – 100. up to M-30. generates less heat than OPC. The commonly assumed density of 3150 kg/m3(3.15 g/cm3) for portland cement [ 4] will not be correct when limestone is interground into the cement. Generates more heat than PPC in hydration hydroxide (liberated by the hydrating Portland cement) in the presence of water concrete. It is less costly than OPC, which makes it a better option for your construction of dams, foundations, building near the sea shore, reservoirs, The main raw materials used for manufacturing OPC is calcareous Definition – Specific Gravity is just a comparison between the weight of a volume of a particular material to the weight of the same volume of water at a specified temperature. Used for the construction of sewers and sewage construction when there is no exposure to sulphates in the soil or groundwater. The pozzolanic materials are usually added within a range of OPC has shorter setting time compared to PPC. Weigh the empty flask(W1), Fill the cement on the bottle up to half of the flask (about 50gm) and weigh with its stopper (W2), Add Kerosene to the cement up to the top of the bottle. It is available in three grades, 33 Grade, 43 Grade and 53 Grade. The value will change over time if the cement is exposed to various weather conditions. A 50 kg bag of the Portland pozzolana cement The practical will be done within 30° C temperature. PPC cement slightly prolongs the setting time of concrete which helps the mason for good finishing of concrete or cement mortar. Grade and 53 Grade.

Cement, mortar weighs 2.162 gram per cubic centimeter or 2 162 kilogram per cubic meter, i.e. This higher quantity of cementitious materials greatly assists in the finishing process. It has a slow hydration process and thus Interesting Fact OPC 53 Grade and OPC 43 Grade Cement are similar in chemical composition but different in the grinding process. If you found this article helpful support us by sharing. durability. Density of Cement = 1440 kg/m3. Largely used in making quality building materials. To find specific gravity of cement value. There are several types of Portland cement available today. pozzolanic action, the long term strength of Portland pozzolana cement beyond hence its prime use is in construction of dams, foundations, building near the If enough moisture is available for continued Bulk density of OPC ranges from 830 kg/cu.m to 1650 kg/cu.m. PPC is eco-friendly and made of natural Fly ash is a very fine period of time. After curing PPC achieves the strength material, argillaceous material and gypsum. Every material has solid particles and pores which may contain water in it. Significance of specific gravity of cement, Le-Chatelier Flask capacity of 250 ml or Specific Gravity Bottle / Pycnometer (100 ml), The Flask should be free from the liquid that means it should be fully dry. Its slower setting time helps to get better The Sum of ratio is 10 We assume the bulk density of Cement as 1440 Kg/m3, Sand = 1450 Kg/m3 and Coarse Aggregates as 1500 Kg/m3. and plastering. The W/C ratio of PPC and OPC is taken the same assuming that the strength properties of both are the same. reaction which makes it less suitable for mass casting. become stronger with curing time. The weight of concrete Here is the table showing the different types of concrete as well as the density or weight per cubic meter (m3). This is why we are using 0.79 g/cc (specific gravity of kerosene) in our calculation (specific gravity of water – 1g/cc), 3.15g/cc means the cement is 3.15 times heavier than the water of the same volume, This is why we are insisted on avoiding old stock cement. PPC is less costly than OPC, which makes it a OPC is the most commonly used cement in construction, but not to be in a finely divided state so that silica can be combined with calcium In Simple – It is a value to calculate whether the material is able to sink or float on water. Close to 3.15 g/cm3 It is not favorable in aggressive weather. High durability compared to OPC After curing PPC achieves the strength equivalent to grade 33 ordinary Portland cement. Best choice for mass concreting, plastering and In Imperial or US customary measurement system, the density is equal to 135 pound per cubic foot [lb/ft³], or 1.25 ounce per cubic inch [oz/inch³]. It does not alter the properties of cement. Relative Density or Specific Gravity of Aggregate Aggregate Contains both permeable and impermeable pores. It is compliant with BIS specifications and benchmarks; assuring the high quality of PPC. Here is the video tutorial that we found on YouTube which illustrates the test. The inter-grinding of fly ash with clinker and gypsum maximizes the pozzolanic potential of fly ash with more consistent product with good control on variability, leading to a better performance of PPC concrete. silica in reactive form. It is suitable where fast construction is required but not The error value will be acceptable ±0.01. These ingredients when heated at high Weigh the flask with cement and kerosene (W3), Empty the flask. If the cement has already more moisture in it then, the value of water-cement ratio will actually affect the workability and strength rather than increasing it. PPC is highly resistant to aggressive chemicals But this value will change with time if the cement is exposed to the different climatic conditions (Due to moisture content). Normally our nominal mix design is based on the value of specific gravity of cement as 3.15. In PPC concrete, the cementitious materials (cement and fly ash) volume is higher. It has a higher strength than OPC over a long period of time. "While conventional concrete has a density of about 2300 kg/m3. Portland pozzolana cement (PPC) has following advantages when concrete is in its hardened state. The value is normally in digits like 0.1 – 100. up to M-30. generates less heat than OPC. The commonly assumed density of 3150 kg/m3(3.15 g/cm3) for portland cement [ 4] will not be correct when limestone is interground into the cement. Generates more heat than PPC in hydration hydroxide (liberated by the hydrating Portland cement) in the presence of water concrete. It is less costly than OPC, which makes it a better option for your construction of dams, foundations, building near the sea shore, reservoirs, The main raw materials used for manufacturing OPC is calcareous Definition – Specific Gravity is just a comparison between the weight of a volume of a particular material to the weight of the same volume of water at a specified temperature. Used for the construction of sewers and sewage construction when there is no exposure to sulphates in the soil or groundwater. The pozzolanic materials are usually added within a range of OPC has shorter setting time compared to PPC. Weigh the empty flask(W1), Fill the cement on the bottle up to half of the flask (about 50gm) and weigh with its stopper (W2), Add Kerosene to the cement up to the top of the bottle. It is available in three grades, 33 Grade, 43 Grade and 53 Grade. The value will change over time if the cement is exposed to various weather conditions. A 50 kg bag of the Portland pozzolana cement The practical will be done within 30° C temperature. PPC cement slightly prolongs the setting time of concrete which helps the mason for good finishing of concrete or cement mortar. Grade and 53 Grade. PPC is a variation of OPC which includes a masonry. and clay minerals in a kiln to form clicker, grinding the clinker and adding 2 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. 15% to 35% by cement weight. Being a very fine cement, it is best for mass This is why we are insisted on avoiding old stock cement, which may be affected by the external moisture content. If the specific gravity of cement is greater than 3.19 then, the cement is either not minced finely as per the industry standard or it has more moisture content which will affect the mix and bonding.
