Why Does Concrete Change Color? Causes Solutions
A low water to cement ratio affects the hydration of the cement which creates a darker color. Concrete surfaces that are troweled too early will increase the water to cement ratio at the surface which lightens the color. Mixture inconsistency can create a wide array of color discolorations based on what''s in the mix and how much.

Volume Changes of Concrete
The volume of concrete begins to change immediately after the water comes into contact with the cement. Early volume changes, within 24 hours, can influence the longterm volume changes and potential crack formation in hardened concrete. Chemical shrinkage refers to the reduction in absolute volume of solids and liquids in paste resulting from cement hydration. The absolute
