There is one mistake in the diagram of reaction No. 5. Fe2O3 is on both sides of the reaction, which is incorrect. On the right side, It should be Fe3O4.

This is the best explanation ever for cement hydration that's available online! Your efforts in putting this together are truly appreciated! I am here to refresh some theoretical concepts before my comprehensive exam next week! Wish me luck!

I'm taking an Environmental Geochemistry college class and this is a great explanation of pourbaix diagrams, although in our class we refer "potential/V" as "Eh" so we call the diagrams "Eh-pH diagrams" instead, maybe its a colloquial thing.

Why is anybody surprised that CO2 is produced by heating the ingredients for Portland Cement. The limestone is literally from dead sea creatures ... the process is liberating the carbon from the dead sea creatures and returning it to the atmosphere where new life can use it to grow.

You said surface tension is acting towards bulk liquid Then why is it said that direction of surface tension is along the surface ?

Why do we need to CaOH2 during the reaction of Limestone and Aluminate sources with water, is it because we need a Calcium source other than Limestone, if so why is Limestone not enough as Calcium source?
@chandrasekarramaiah21262 ай бұрын
Because the Carbonate ions in the limestone are captured by highly reactive C3A to form AFm phases, the Ca in limestone cant directly react...simply CH + Alumina forms a reactive compound whereas Limestone isn't, which later is displaced.

5:35 if final concrete has 4.5% porosity then why aren't we using this material as water purification filters? instead they sell ceramic filters which are much more expensive. But with one bag of cement you can make hundreds of water filters. Why isn't cement used as water filter?

you should use no mortar if you want it to last 1000 years. dry stack your stones.
