About this Exam

Prepare with the ACI Concrete Field Testing Technician - Grade I practice quiz. This question bank includes 50 questions covering concrete, astm, aggregate, surface, and content. Use it to review important concepts, identify knowledge gaps, and build confidence for the related exam, course, or assessment.

Sample Questions

Question 1
According to ASTM C136/C136M, what is the primary reason for performing a sieve analysis on fine and coarse aggregates?
To determine the moisture content of the aggregate
To measure the resistance of the aggregate to abrasion
To determine the particle size distribution (grading) of the aggregate
To calculate the specific gravity of the aggregate
Question 2
A technician is tasked with determining the bulk density (unit weight) of a coarse aggregate sample by rodding, in accordance with ASTM C29/C29M. The procedure involves placing the aggregate into a calibrated measure in how many approximately equal layers?
One continuous layer
Two layers
Three layers
Four layers
Question 3
Which of the following properties is determined using the Los Angeles (L.A.) abrasion test (ASTM C131)?
The percentage of voids in an aggregate sample
The resistance of coarse aggregate to degradation by abrasion and impact
The amount of material finer than the 75-µm (No. 200) sieve
The absorption capacity of fine aggregate
Question 4
A laboratory is testing a coarse aggregate sample for specific gravity and absorption according to ASTM C127. The aggregate is soaked for a prescribed period and then dried to a saturated-surface-dry (SSD) condition. What does the SSD condition signify?
The aggregate has been oven-dried to a constant mass.
The aggregate's permeable pores are filled with water, but the surfaces of the particles are dry.
The aggregate is completely submerged in water.
The aggregate contains no moisture in its pores or on its surface.
Question 5
When an accurate determination of the material finer than the 75-µm (No. 200) sieve is required for an aggregate sample, ASTM C136 states that dry sieving alone is insufficient. Which test method should be performed prior to the dry sieve analysis?
ASTM C29 (Unit Weight)
ASTM C127 (Specific Gravity and Absorption of Coarse Aggregate)
ASTM C131 (L.A. Abrasion)
ASTM C117 (Materials Finer than 75-µm Sieve by Washing)
