FE Civil Engineering Materials Questions
with Complete Solutions
Cement Paste cement + water
Mortar cement paste + water
Concrete cement, water, sand, and aggregate
Hydration The chemical reaction between cement particles and water
Entrapped voids These are trapped air due to PCC handling of the cement. They decrease
strength and increase permeability.
Entrained air These are produced by microbubbles and increase the durability of the cement.
Setting This refers to stiffening or change from plastic to solid state in cement.
Hardening This refers to the strengthen gain of the cement paste.
