Is cement recyclable?
No, cement is not recyclable. Because when it is mixed with water chemical reaction takes place and gains strength and hardens. The hardened cement cannot be used as a recycled one because no chemical reaction takes place when mixed with water. ...
Asked in Chemistry
Is the mixture of water and cement a physical or chemical change?
This is a fun question, because the answer is "BOTH". CHEMICAL: Mixing water with cement hydrates cement components. Hydration is a class of chemical reaction, or change. Notably, quicklime, or calcium oxide, becomes hydrated to calcium hydroxide, a reaction that releases heat. PHYSICAL: Cement powder mixed with water liquid produces a solid physically distinct from the original constituents. ...

Asked in Civil Engineering
Who is making cement civil engineers or chemical engineers?
If your asking who does the mix design for cement or concrete that would normally be done by civil/construction engineers. The chemical engineers may play a roll if they are creating a new additive to make the cement or concrete dry faster while retaining or improving its design strength. ...
What is cement?
Cement is a building material made by grinding calcined limestone and traces of clay and gypsum. Its key use is as an ingredient for concrete or mortar. Cement is a heterogeneous mixture. Cement is used as a binding material for sand/aggregate. Cement is hardened by adding an appropriate quantity of water. Cement is a powder that is made of calcined lime and clay. Cement is mixed with sand, gravel and water to form concrete. The cement has a chemical reaction with water, and hardens....

What are the chemical properties of sulphate resistant cement?
The sulphate resistant cement is made with low C3A content is found to be effective. Such cement with low C3A and comparitively low C4AF content is known as sulphate resisting cement. This cement has a high silicate content.The specification generally limits the C3A content to 5 percent. ...
