Sample Questions

Question 1
What defines self-consolidating concrete (SCC) according to ACI 237R?
Highly flowable, non-segregating concrete that can spread into place, fill formwork, and encapsulate reinforcement without mechanical consolidation
Concrete with a slump of 8 inches or greater measured per ASTM C143
Concrete containing at least 10% supplementary cementitious materials
High-strength concrete with compressive strength greater than 8,000 psi
Question 2
Which ASTM standard covers the slump flow test for self-consolidating concrete?
ASTM C1611/C1611M
ASTM C143/C143M
ASTM C1621/C1621M
ASTM C1610/C1610M
Question 3
When performing the slump flow test per ASTM C1611, the final spread is calculated as:
The average of two diameters measured approximately perpendicular to each other, to the nearest 1/2 in.
The maximum diameter measured in any direction
The diameter measured parallel to the longest axis of the spread
The circumference of the spread divided by pi
Question 4
A typical target slump flow range for most SCC applications per ACI 237R is:
18 to 30 in. (455 to 760 mm)
4 to 8 in. (100 to 200 mm)
8 to 12 in. (200 to 300 mm)
32 to 40 in. (815 to 1015 mm)
Question 5
During the slump flow test, the T50 time is:
The time, to the nearest 0.2 s, from first movement until the concrete spread first touches the 500-mm (20-in.) circle
The total time from raising the mold until flow stops
The time for concrete to drop 50 mm inside the slump cone
The time required to fill the slump cone
