Who invented concrete

romans

Early form of concrete

pozzolana

Combination of Pozzolana

quicklime, water, sand, gravel

Cementing Material, reactive siliceous material to hydrated cement,

such as asphalt, resins, etc.

binder

Granular Material; such as Sand, Gravel, Crushed Stone, etc.

aggregate

Lightweight aggregates occupies _% of the volume of concrete

60-70

Distribution of particle sizes present in an aggregate

grading

A Structural Concrete with Pre-stressing tendons (steel) or Non-Prestressed Reinforcement

reinforced concrete

A Structural Concrete with no (or less) reinforcements. It also has no admixture

plain concrete

Type of cement that sets & hardens by chemical interaction w/ Water. It is Incapable underwater (example: Portland Cement & Ground Granulated Blast–Furnace Slag)

hydraulic cement

Type of hydraulic cement made of Pulverized PC Clinker, combination w/ Calcium Sulfate

portland cement

Type 1 Portland Cement

general purpose

Type 2 Portland Cement that has lower generation of heat during hydration and moderately sulfate resistant

moderate sulfate resistance

Type 2 Portland Cement are typically used in

foundations, piers, retaining walls, pavements, and water structures.

Type 3 Portland Cement where reduced curing is required; faster schedule

high early strength

Type 3 Portland Cement are typically used in

cold weather, concrete repairs, precast construction

Type 4 Portland Cement where temperature rise and thermal cracking are major concerns.

low heat of hydration

Type 4 Portland Cement are typically used in

dams, nuclear plant

Type 5 Portland Cement that has High Sulfate Concentration

sulfate-resistant
