10 parts water to 1 part acid
high water cement ratio , fresh concrete not mixed well , the fresh mix not compacted well ,
1 part vinegar to 2 parts water.
mixing cement with water is a irreversible change
Cement reacts with water (this reaction is known as hydration).
Concrete is probably the most important building material today and is used as an alternative for brick/wood since the Roman & Egyptian times. It is composed of cement,stone[gravel], sand and water which is a key ingredient that hardens the concrete. When reinforced with steel bars it is even more useful.

Slump test
Water/cement ratio law states that the strength of concrete is only dependent upon water/cement ratio provided the mix is workable.Strength of concrete primarily depends upon the strength of cement paste.Similarly, the strength of the paste increases with cement content and decreases with air and water content.
Why does concrete mix with low water cement ratio resulted in hardened concrete having higher strength than those with high water cement ratio?
Clay w/fire is brick - - - Concrete + Brick = Brick House Water + Cement = Concrete Clay + Limestone = Cement Stone + Cockleshell = Limestone
0.4
Water cement ratio is defined as the indicator of strength is the ratio of water used compared to the amount of cement.Lower the W/C ratio, higher will be the strength.A minimum of W/C ratio 0.3 should be adopted.
it depends on the type of mix and water cement ratio.
the strength of concrete is effected by water /cement ratio as the water/cement ratio increases the strength of the concrete decreases
