CONE 240 Exam Questions AND Correct Answers
3 Stages of Concrete - ✔✔- fresh or plastic state
- setting stage
- harden state
28 days for concrete to reach max strength
Absorption Capacity - ✔✔Moisture content of
aggregate when all water accessible
Aggregate Moisture States - ✔✔Aggregates absorbs /
gives off a lot of water
Aggregate Properties - ✔✔shape, texture, soundness,
toughness, absorption, specific gravity, strength and
modulus, gradation, deleterious materials and
cleanness, alkaline reactivity, affinity for asphalt
Aggregate Uses - ✔✔Stability, Drainage, as fillers
usually under foundations
,aggregates - ✔✔absorbs / gives off a lot of water
Alkali-Aggregate Reactivity - ✔✔Silica in some agg.
reacts with alkalis (Na_2O, K_2O) in portland cement
- causes excessive expansion
-cracking
-popouts
Angle of Friction - ✔✔Resistance to soil slip, and the
more load, the more bonding
Apparent Solid - ✔✔Voids amongst aggregate particle
Voids within aggregate particle
Apparent solids - ✔✔Are apparent because we are
unaware of any water impermeable pores inside the
solids
, Apparent Specific Gravity - ✔✔functional definition,
mass of oven dry agg / volume of agg
Apparent Unit Weight - ✔✔weight of solids / apparent
volume of solids
Apparent Volume - ✔✔Volume based on the
assumption of voids in the cement
Apparent Volume - ✔✔Volume of apparent solids
apparent volume is used - ✔✔because of the voids that
could be in the aggregate
Asphalt Affinity - ✔✔affects the bond between asphalt
binder and aggregate
Asphalt is the best when - ✔✔N = 0.5 on fuller's scale
