How does mixing water and cement change their properties?
When water is mixed with cement the following action takes place, . Evolution of heat . Hydration of cement . Finally hydrated particles will be formed which give strength… to the structure. . Ex: CaO + H 2 O ----> Ca(OH) 2 .
If you mix cement ,sand and water you get mortar If you mix cement and stone pebbles or chips you get concrete Concrete.Sometimes gravel is mixed with it, too.
Actually both physical and chemical changes are happening duringcement mixing.
Well I'm just guessing so yeah i think that explode
It is Motar.
Yes. Read the instructions. ANS 2 - You can, but it has limited uses as it gets quite brittle.
Cement mixed with sand and water makes mortar.
I dont think so . because water is totally bind together with the cement and because of water the cement can be transform into something solid .
mixing cement with water is a irreversible change
Cement reacts with water (this reaction is known as hydration).
It makes a wet-like gray liquid that is similar to cement but it's actually like a wet type of cement.
No, once water is mixed with cement, an irreversible reaction occurs
Short Answer: When adding water to cement a chemical reaction called hydration takes place, transforming the calcium and silicates into new mineral forms through an exotherm…ic reaction. It takes minutes to days or longer to complete depending on the particular recipe being used and if it is combined with other materials such as those used to make concrete. More: Contrary to popular belief, concrete does not "dry," it cures. When properly mixed, water does not leave the mixture but gets chemically incorporated into the resulting minerals formed by chemical reaction. That is the reason newly poured concrete is often protected from evaporation since evaporation changes the chemical mix near the surface and the deficiency of water changes the final type of material and its properties. We say cement sets or cures when mixed with water to describe a series of hydration chemical reactions. The constituents harden and the interlocking of the crystals gives cement its strength. Using cement or making concrete is a lot like making bread. There is a huge knowledge base based on experience of what ingredients go into it and the process of putting them together and cooking the mixture, but the detailed chemistry of what takes place in the hardening phase is not easy and not completely understood and changes somewhat for different recipes. Making cement is better understood. It takes limestone and silica. The first step is called the calcining of limestone (calcium carbonate) into lime (calcium oxide) which give off carbon dioxide. It takes place in a kiln heated to 1650F (900C). The second reaction is the bonding of calcium oxide and silicates to form dicalcium and tricalcium silicates. This is done at higher temperature. Other minor ingredients may be added to adjust final properties.
