1) Moisture captured in the aggregate voids in the saturated surface dry(SSD) condition is not available for ________________________ , nor does it improve the _______________________ of concrete.

​2) Reducing the ______________________________, increases the strength of the material.  

​3) A ___________________ polymer rebar not only results in a lighter concrete but a stronger material with a higher yield strength.

​4)

Portland cement concrete, steel-reinforced concrete, asphalt concrete and engineered word are examples of ___________________ composites.

5) As the _______________ Ratio in portland cement concrete is increased, the compressive strength is drastically reduced.
