If thecementhas exposed to extreme moisture content then, thespecific gravity of cementwill 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 ofspecific gravity of cementas 3.15. The value will change over time if thecementis exposed to various weather conditions.
Sep 10, 2017·Specific gravity test/Density ofCement test: As per Le Chatelier’s Principle,Specific gravity of cementis determined by Le Chatelier’s Flask method. And theIS code for Specific gravity testis IS 2720- Part 3. Apparatus Required for Le Chatelier’s Principle:-1.Cement2. Kerosene 3.Specific Gravity Bottlecapacity of 250 ml with stopper. 4.
Thespecific gravitydefines that the substance is how much heavier than water orreferencesubstance of the same volume. Thisspecific gravity of cementranging from 3.1 to3.16 g/cc. By this statement, we may ensure thatcement3.1-3.16 times heavier than this water of this same volume, and it sinks in water.
Specific gravitycan be defined as the density of any substance to the density of otherreference substanceat aspecified temperature. For example, to determine thespecific gravity of cementwill consider water asreference substance.

PortlandCement Specific Gravity Specific gravityis normally used in mixture proportioning calculations. Thespecific gravityofportland cementis generally around 3.15 while thespecific gravityof portland-blast-furnace-slag and portland- pozzolancementsmay havespecific gravitiesnear 2.90 (PCA, 1988 [1] ).
In addition to hydrauliccement, the Le Chatelierspecific gravityflask can also be used to obtain thespecific gravityof dust, sand, and other fine materials. Thisspecific gravity of cementis a need for mixture-proportioning calculations. Thisspecific gravityof portlandcement(without voids between particles) is about 3.15 and can be ...
Oct 14, 2017·SPECIFIC GRAVITY OF CEMENTRANGE The particle density of Portlandcementranges from 3.10 to 3.25 Mg/m³, averaging 3.15 Mg/m³. For mixture proportioning, it may be more useful to express the density as relative density (specific gravity). On an av...
Therefore, thespecific gravityof soil solids containing extraneous matter, such ascement, lime, and the like, water-soluble matter, such as sodium chloride, and soils containing matter with aspecific gravityless than one, typically require special treatment (see Note 1) or a qualified definition of theirspecific gravity.
Thespecific gravityis normally defined as the ratio between the weight of a given volume of material and weight of an equal volume of water. The portlandcementhave aspecific gravityof value around 3.15. When it comes to portland pozzolan cements and portland blast furnace cements the value will come near to 2.90 (As per PortlandCement...
Thespecific gravityof slagcementranges from 2.85 to 2.94, depending on the slag source, as compared to 3.15 for portlandcement. The difference inspecific gravitymeans a greater volume of slagcementwill be used to replace the same mass of portlandcement.
