Concrete Materials, Mixture Proportions, and Specifications
Classify ASTM C150 cement Types I through V and C595 blended cements by composition, heat of hydration, and sulfate resistance, then match each type to a described project exposure.
Differentiate C618 Class C and Class F fly ash, C989 slag cement, and C1240 silica fume by their effect on set time, early versus late strength gain, permeability, and sulfate resistance.
Evaluate a C33 aggregate submittal: check gradation against the size-number limits, compute fineness modulus from a sieve analysis, and apply C127/C128 bulk specific gravity and absorption values to a batch weight calculation.
Distinguish C494 admixture Types A through G and C260 air-entraining agents by function, and predict the field symptoms of overdose, underdosing, and cement-admixture incompatibility.
State C1602 mixing water limits and map ACI 318 exposure classes (F, S, W, C) to their required maximum w/cm and minimum f'c.
Your checkpoint
A one-page reference table of cements, SCMs, and admixtures (type, standard, function, caution) plus a 40-question Domain 1 quiz scored at 80% or higher.
Concrete Materials, Mixture Proportions, and Specifications
Compute a complete ACI 211.1 absolute-volume mixture proportion (cement, SCM, water, fine, coarse, air) for a specified f'c, slump, air content, and nominal maximum aggregate size.
Correct laboratory batch weights to field batch weights using aggregate moisture content and absorption, and explain why saturated-surface-dry is the reference condition.
Interpret ASTM C94 requirements for ready-mixed concrete: batching tolerances, discharge time and drum revolution limits, and when water may be added at the job site.
Trace how a specification flows from ACI 301 and ACI 318 into the submittal, verification, and acceptance sampling frequency an inspector must enforce.
Your checkpoint
Two hand-worked mix proportioning problems (one air-entrained, one non-air-entrained) including absolute volumes, SSD weights, and moisture-corrected field weights, with no more than one arithmetic error across both.
Sampling and Fresh Concrete Testing (slump, air content, temperature, unit weight)
Execute ASTM C172 sampling correctly: number and location of samples, remixing, and the minimum sample size needed for the required tests.
Perform and interpret ASTM C143 slump, including proper lift, rodding, timing, and recognition of shear and collapse slumps.
Compare ASTM C231 pressure-meter air content with ASTM C173 volumetric air content and select the correct method for lightweight, highly porous, or high-slump concrete.
Measure concrete temperature per ASTM C1064 and calculate unit weight, yield, and relative yield per ASTM C138, then judge whether the batch meets the specified values.
Your checkpoint
A 30-question fresh-concrete problem set with all calculations shown, including three full unit weight/yield computations and five slump-versus-air decision scenarios, scored at 85% or higher.
Specimen Preparation, Curing, and Compressive Strength Testing
Contrast ASTM C31 field-made specimens with ASTM C192 laboratory specimens in terms of sampling, consolidation, and number of layers and strokes per layer.
Demonstrate correct consolidation by rodding versus internal vibration for 4 by 8 in. and 6 by 12 in. cylinders, and identify the defects created by over- and under-consolidation.
Apply ASTM C511 curing environment tolerances (temperature and humidity for moist rooms and saturated lime water) and state the initial curing limits for field-stored cylinders.
Document specimen identity, transport, and protection so that a cylinder can be traced from sample to test report without ambiguity.
Your checkpoint
A written specimen preparation and curing procedure card, cross-checked line by line against C31 and C511, plus a 25-question Domain 3 quiz scored at 80% or higher.
Specimen Preparation, Curing, and Compressive Strength Testing & Field Inspection, Quality Control, and Acceptance Decisions
Prepare and test cylinders per ASTM C39: verify specimen dimensions, apply the correct load rate, record the maximum load, and compute strength to the required reporting precision.
Select between sulfur mortar capping (C617) and unbonded neoprene pads (C1231), and diagnose invalid breaks from the fracture pattern.
Characterize fracture types (cone, cone and shear, shear, columnar, cap or end-grain) and decide whether a result must be flagged or discarded.
Interpret ACI 318 strength evaluation rules: the three-consecutive-test average, the single-test lower limit, and the core criteria of 85% average and 75% individual core.
Your checkpoint
A cylinder data workbook covering ten test sets: computed strengths, fracture type, validity call, and pass/fail against a stated f'c, with a short written rationale for each acceptance decision.
Field Inspection, Quality Control, and Acceptance Decisions
Build a pre-placement inspection checklist covering formwork, reinforcement cover, embedments, construction joints, and approval to place.
Audit a delivery ticket against the approved mix design: batch weights, water added, admixture amounts, time of batching, and revolutions at discharge.
Apply hot-weather (ACI 305) and cold-weather (ACI 306) limits to placing, finishing, and protection, and specify when the inspector must stop the placement.
Verify curing method, duration, and start time against the specification, and record nonconformances so they can be closed out.
Your checkpoint
A field inspection packet for one simulated placement: completed pre-placement checklist, three audited delivery tickets, and a nonconformance log with at least two entries and their corrective actions.
Field Inspection, Quality Control, and Acceptance Decisions & Safety, Test Standards, Records, and Reporting
Differentiate acceptance, referee, and informational testing, and explain how sampling location bias and technician variability affect a dispute.
Evaluate low-strength results and prescribe the correct follow-up sequence: review of records, additional testing, core extraction per ASTM C42, and load test or engineering evaluation.
Outline the safety controls for respirable crystalline silica (OSHA 1926.1153 Table 1), cylinder handling and lifting, wet-testing electrical hazards, and hazard communication on a concrete site.
Determine which test standards are referenced for each field activity and what happens when the wrong standard, wrong specimen size, or wrong curing regime is used.
Your checkpoint
A written low-strength investigation memo (one page) with a defensible acceptance recommendation plus a 20-question safety and standards-reference quiz scored at 85% or higher.
Safety, Test Standards, Records, and Reporting & Concrete Materials, Mixture Proportions, and Specifications & Sampling and Fresh Concrete Testing (slump, air content, temperature, unit weight) & Specimen Preparation, Curing, and Compressive Strength Testing & Field Inspection, Quality Control, and Acceptance Decisions
Compile the record set required for a complete concrete test report: project and mix identification, sampling and test dates, specimen age, test method, results, and technician certification.
Identify and correct the gaps in a sample report so it satisfies ASTM C39, C31, and C143 reporting requirements without missing fields.
Diagnose personal weak areas from the cumulative quiz and problem-set error log, then re-drill the two weakest domains to demonstrated mastery.
Complete two full-length timed practice exams under exam conditions and analyze every missed item by domain and root cause.
