Foundations cast at the same elevation as the soil grade are known as: -
ANSWERShallow
What causes concrete to set and become hardened? - ANSWERHydration
Cement forming chemical bonds with water molecules, which sets things in motion to
become an extremely hardened material. - ANSWERHydration Process
In general, how long does it take for concrete to move from a plastic state to a hardened
state, depending on weather and admixtures? - ANSWER30 minutes to 5 hours
Many project specifications consider concrete rejectable after it has bee what? -
ANSWERBatched for 90 minutes
, Hydration is "exothermic", meaning what? - ANSWERIt produces heat.
What are pozzolans? - ANSWERsiliceous or siliceous/aluminous materials which have
little to no cementitious value alone; react with lime and water to form a product similar
to C-S-H.
Aggregates not conforming to ASTM C33 or C330 must be what? - ANSWERShown by
test or actual service to produce concrete of adequate strength and durability and
approved by the building official.
Aggregates make up what percent of concrete? - ANSWER60-80%

ASTM C33 is divided into 2 Categories. What are they? - ANSWERCoarse & Fine
What is honeycomb? - ANSWERVisible voids in the concrete
What are the parameters for maximum coarse aggregate size permitted in concrete
mix? - ANSWER1/5 the narrowest dimension between sides of forms, 1/3 the depth of a
slab, 3/4 the minimum clear spacing between individual reinforcing bars, tendons, or
ducts
Water for concrete mixing must conform to what ASTM standard? - ANSWERC1602
Non-potable water can be used in concrete without any kind of testing. True or False? -
ANSWERFalse.
Potable water can be used without testing.
When is concrete considered batched? - ANSWERWhen water is added
The amount of water in pounds divided by the amount of cement in pounds. -
ANSWERWater/cement ratio
