How has chemistry changed our daily lives?
All around us are chemical products: paper, cement, drugs, paints, solvents, etc.
How does knowledge of chemistry help architect?
the knowledge of chemistry helps a architect in many ways like: 1)he can use the best qulity cement in the construction work...that is he need to have the knowledge of the behaviour of the magnesium and other constituent elements in the cement 2)he can have better idea in the usage of metals in the construction
What is an example of a mixture in chemistry?
Examples: beer, glass, cement, tooth paste, fried potatoes, lemon, aqua regia, denatured alcohol, etc.
What is the most important ingredient of concrete?
Usually the sand and aggregate (filler stone) is the largest percentage of concrete, however from a chemistry standpoint the cement is, by far, the most important ingredient.
What can you add to Portland cement to make it sulphate resistant?
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.
Why is gypsum added to Portland cement?
Gypsum is added to portland cement to retard C3A hydration
What makes up masonry cement in detailed version?

One of the main components of cement?
The components of cement are,C3S - 54.1 %C2S - 16.6 %C3A - 10.8 %C4AF - 9.1 %
Chemistry of SRC cement?
Sulphate resisting cement:Low C3A ContentLow C4AF contentCa(OH)2 + SO2 ---> CaSO3 + H2OIn the above equation water is evolved, so hydration process is continuous in SRC
What are the chemical properties of sulphate resistant cement?
Advantages of using sulphate resisting cement,It is used in marine constructionUsed in foundations and basements where soil is infested with sulphates.Concrete to be used in construction of sewage treatment works.Used in fabrication of pipes which are likely to be buried in sulphate bearing soil.

How does Portland cement differ chemically from other cement?
I assume you are contrasting portland cement with fly ash to portland cement with powdered slag? (Fly ash is from coal furnaces, powdered slag is from oil-burning furnaces). Slag is very similar to portland cement, and can be used to cheaply replace up to 50% of portland cement in concrete. This is less expensive, and the slag makes the hardened concrete more resistant to de-icers. Fly ash is not similar to portland cement, but is also good to resist de-icers. But since fly ash is not similar to portland cement, only 20 to 30% of portland cement can be replaced by it. The main difference in chemistry are the amounts of oxygen-containing elements. (Called 'oxides'). For example, portland cement has 65% of C2O, Slag cement has 45%, and Fly ash contains 25% For SiO2 portland cement 20%, Slag cement 33%, and Fly ash 37% For Al2O3 portland cement 4%, Slag cement 10%, Fly ash 16%. There are other very minor differences in chemistry.
