Let the weight recorded be denoted as W3. But if “Cement” is used as a sample substance then kerosine would be the reference substance. 2. | Advantages, Disadvantages & Uses, What is Irrigation? b. Weighing Balance with an accuracy of 0.1gm. To determine the unit weight of a substance like cement, multiply the specific gravity of the cement by the unit weight of water. At 1cm from the bulb, the stem of the flask is marked with 18 ml and is grated up to 24 ml. Moisture is very harmful to cement. Some types of cement such as PPC, Portland Blast furnace slag will have the value near 2.90.. The specific gravity of iron related to water with density 1000 kg/m 3 is. Properties of Cement- Physical & Chemical. One of the essential property of cement is the specific gravity of cement. The Le-Chatelier’s flask consists of thin glass with a bulb at the bottom. Density, p = mass of cement/displaced volume. The fine aggregate specific gravity test (Figure 1) is used to calculate the specific gravity of a fine aggregate sample by determining the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. Cement, mortar weighs 2.162 gram per cubic centimeter or 2 162 kilogram per cubic meter, i.e. This specific gravity of cement is a need for mixture-proportioning calculations. For Portland cement it's 3.1-3.16 gm / cc. The density will be displayed as a specific gravity ratio in the lower text box. While the specific gravity value of the Portland Pozzolana cement is around 2.90 g/cc. The portion above this 24ml mark is in the form of a funnel having a diameter of 5cm. If the specific gravity is greater than 1, then it sinks in water. On the other words, it is the ratio of the mass of a substance to the mass of a reference substance.
