03-07-2021· For most of the cements we use in construction has a specific gravity of cement ranging between 3.1 to 3.16 g/cc and a density of 1440 Kg/m3. But that doesn’t mean it stays same for all types of cement we have. Moreover, specific gravity itself is an important quality control parameter for cements while determining mix design of concrete.
The specific gravity of cement is determined by the Le-Chatelier’s Flask Method which is briefly described below. i. Apparatus & Equipment Required. a. Le-Chatelier’s Flask: The Le-Chatelier’s flask consists of thin glass with a bulb at the bottom. The bulb has a mean diameter of 7.8cm and a capacity of 250ml.
Specific Gravity of Cement Sg is given by the formula, Here, the specific gravity of kerosene is 0.79g/cc. Duplicate determination of specific gravity should agree within 0.01. To get an accurate result, the flask should be held at a constant temperature before each reading is taken.

Procedure for Specific Gravity determination for Aggregate coarser than 6.3mm. About 2 kg of aggregate sample is taken, washed to remove fines and then placed in the wire basket.
materials, whether by weight or volume should be entered and the specific gravity of the pozzolanic materials should be entered. In the CECALC Concrete Mix Design calculation the specific gravity for Type I cement, 3.15 is used. Step 5, Calculation of cement content: This step is performed by the calculation and will be displayed in the output.
gravitational force. In the design of an underground precast concrete structure a certain thickness of the walls and slabs must be implemented, whereas other products, such as HDPE have thinner wall sections and tend to float up out of the ground when they are pumped (if not properly anchored). With a specific gravity of 2.40, precast concrete
