Portland cement is simply a mixture of limestone and clay heated in a kiln to 1400 to 1600 degrees centigrade (2550 to 2990 F). Due to the high temperatures and large amounts of materials being used, considerable attention is given to each stage of the production process.

OPC 53 Grade Cement: Key Features While the chief chemical constituents of ordinary Portland Cement (OPC) are Calcium, Silica, Alumina and Iron, cement manufacturers continuously research and make efforts to further strengthen and improve the quality and other features of this particular type of cement .

We offer Ordinary Portland Cement (OPC) that is used in all general constructions, especially in major and prestigious projects where cement is needed to meet stringent quality requirements. It can also be used in concrete mortars and grouts, etc. Ordinary Portland Cement is compatible/consumable with admixture/ retarders, etc.

Chemical Composition of Cement The raw materials used for the manufacture of cement consist mainly of lime, silica, alumina and iron oxide. These oxides interact with one another in the kiln at high temperature to form more complex compounds. The relative proportions of .

The density of cement may be anywhere from 62 to 78 pounds per cubic foot. Specific Gravity (Relative Density) Specific gravity is generally used in mixture proportioning calculations.

Evaluation of Crushed Concrete Base Strength Prepared for Mississippi Department of Transportation State Study No. 238 Project No. SPR1(59) 106002 160000 Prepared by L. Allen Cooley, Jr., Howard Hornsby, EIT BURNS COOLEY DENNIS, INC. GEOTECHNICAL AND .

Using Density of Cement = 1440 kg/cum (Approx) Volume of 1 Kg of Cement = 1/1440 = cum. Volume of 01 bag (50 kg) of cement = 50 X = cubic meter (cum) Since we know the ratio of cement to sand (1:2) and cement to aggregate (1:4) You're still using the same density of cement for both sand and aggregate.

Sep 01, 2015· Different grades of cement are specified by IS . Cements are mainly classified on the basis of compressive strength of particular cement. For example if cement has compressive strength of 33 N/mm2 then it is classified under grade 33. Mainly 3 grades of cements are used: GRADE 33 ORDINARY PORTLAND CEMENT: Fineness=300 m2/kg

Aerated Concrete is a variety of extremely lightweight concrete ( density 480800 Kg/m 3). This is obtained by using cement, sand, and powdered fuel ash as constituents. 3. Highdensity Concrete: This type of concrete is also called heavy weight concrete. In this concrete type, the density varies between Kg/m 3.

each batch for three test specimens shall consist of 450 ± 2 g of cement 1350 ± 5g of sand 225 ± 1g of water (water/cement ratio = 0,50) the cement, sand, water and a apparatus shall be at the laboratory temperature Mix each batch of mortar mechanically using the mixer () :

To illustrate this latter factor, resistivity measurements have been made of the following cement pastes and mortar: ordinary Portland cement (OPC) paste, w/c=, sulphate resistant Portland cement (SRPC) paste, w/c=, a blast furnace slag cement (BFSC) paste, w/c=, and a dense silicacement (DSP) paste and mortar.
