How white cement is different from OPC?
How white cement is different from OPC?
The production of white cement requires 40\% more energy than OPC and this more heat requirement for burning of raw materials in snowcrete and more energy consumption also leads to lesser strength. Fineness of white cement is 395m2/kg which is also higher than OPC.
Which is stronger white cement or normal cement?
The grey cement is the more commonly used cement everywhere, whereas the white cement is used for specific purposes only, or when a certain kind of finish is required….White Cement v/s Grey Cement.
| Grey Cement | White Cement |
|---|---|
| It has a lower refractive index. | It has a higher refractive index. |
Why white cement is costly as compared to OPC?
White Portland cement is made from raw materials containing little or no iron or manganese, the substances that give conventional cement its gray color. White cement production needs usually 40\% higher energy than the normal grey cement and this contributes to the high price of white cement.
Why white cement is white?
The color of white cement is determined by its raw materials and the manufacturing process. Metal oxides, primarily iron and manganese, influence the whiteness and undertone of the material. After adding pigments, white cements produce clean, bright colors, especially for light pastels.
Can I use white cement instead of cement?
You can use absolutely, it only doesn’t include Fe2O3. White cement is Ordinary Portland Cement, its Fe2O3 content is very low to give white color, it is expensive and no need to use in reinforced concrete….
What is difference between OPC vs PPC cement?
Portland Pozzolana Cement is a variation of Ordinary Portland Cement. Pozzolana materials namely fly ash, volcanic ash, are added to the OPC so that it becomes PPC. PPC has low initial setting strength compared to OPC but hardens over a period of time with proper curing. …
What are the advantages of white cement?
Advantages of White Cement: White cement is a good reflector to the light. It not only gives good looking and charm to the building, but also it saves energy to enlighten the interior and exterior of the building. Products of white cement can be recycled and reused in other products at the end of their useful life.
Is white cement breakable?
White cement is very prone to cracks when it dries. It defers from ordinary grey cement. It is fine grind cement. It starts hydration quickly and generate heat that causes it dry up quickly and forms cracks.
Why white cement is not used for construction?
Use of White Cement: The cost of production of white cement as compared to OPC and PPC is much higher, therefore in ordinary construction like concrete structures, mortar, and plaster, white cement is not recommended. The combination of white cement increases the adhesive characteristic of the lime.
