How can you make portland cement as quick setting and water resistance cement?
Please note that a key correction in terminology is essential before your question can be answered: use the word "concrete" instead of "cement." The answer is to modify your mix (i.e. Portland cement, sand, gravel, and water) by using hydraulic cement to repace part of the Portland cement. The higher the amount of hydraulic cement you add, the quicker the setting time and the impermeability. However, hydraulic cement sets so quickly that you have limit the amount of total mix so as to be able to pour it and form it before it sets.

Why do you apply cavity varnish on gic cement?
To prevent the cement from: - Dehydration of cement, which prevents - Cracking of cement, which avoids, - Discoloration of cement Additional note: - Since GIC is a water based cement, it is sensitive to water so exposing the GIC is also unwise in the sense that it might get contaminated with water, hence over-hydrating the cement and affecting its physical properties - Note that the varnish is applied during the initial phases of GIC setting reaction to allow it to set comfortably, which means right after placement and before polishing - Also note that some authors say that the polishing burs or any instruments that will be used for instrumentation on GIC should be applied vaseline on their working ends
