Engineer Concrete study guide
Engineer Concrete · Work through your exam, one topic at a time.
The Engineer Concrete credential is a professional-level qualification for civil and structural engineers who design, specify, and supervise reinforced and prestressed concrete work. It suits engineers moving from general practice into concrete-focused roles, and it is also taken by materials engineers, QA/QC leads, and senior site engineers who need design-level judgement rather than code-lookup familiarity. The Engineer Concrete study guide has 9 sections and about 3,020 words.
01Concrete Materials and Mix Proportioning
This domain tests whether you can choose constituents and proportion a mixture that satisfies strength, durability and placeability at once, and whether you can defend the water-to-binder ratio, binder content and air content against ACI 211 proportioning, ACI 318 durability limits and the project specification. Cement type per ASTM C150: Type I general purpose, II moderate sulfate resistance and lower heat, III high early strength, V high sulfate resistance; ASTM C595 blended cements are now common.
415 words, about 2 min02Fresh Concrete: Workability, Placement, and Consolidation
This domain tests whether you understand workability as a rheological property rather than a single number, and whether your placement and consolidation decisions would leave the hardened concrete free of voids, cold joints and segregation. Slump (ASTM C143) measures yield stress only and is unreliable above about 190 mm; high-flow mixes need slump flow and T50 (ASTM C1611), J-ring or L-box for passing ability.
352 words, about 2 min03Curing, Finishing, and Early-Age Behavior
This domain tests the link between early-age moisture and temperature history and long-term performance: strength gain, permeability, cracking and surface durability. Questions usually ask what to do, when to do it, and what goes wrong if you are early or late.
350 words, about 2 min04Hardened Concrete Properties and Testing
This domain tests the relationship between specimen, test method and the number you are allowed to use in design: cylinder versus cube, standard versus field curing, and single results versus statistical acceptance. Compressive strength uses 150 by 300 mm cylinders (ASTM C39) moist cured at 23 plus or minus 2 degrees C and tested at 28 days.
322 words, about 2 min05Structural Design of Reinforced Concrete Members
This domain tests strength design to ACI 318: whether you can carry out flexure, shear, development, serviceability and seismic detailing checks with the correct assumptions and resistance factors. Factored load combinations begin with U = 1.2D + 1.6L.
350 words, about 2 min06Prestressed Concrete and Special Structural Systems
This domain tests the mechanics and detailing of prestressed members: how prestress is applied, how losses accumulate, how service stresses are verified, and where post-tensioned slabs, precast systems and shear walls differ from ordinary reinforced concrete. Pretensioned members are stressed in a plant against a bed and bonded to the concrete at transfer; post-tensioned members are stressed after the concrete hardens, through ducts that may be grouted (bonded) or left unbonded.
306 words, about 2 min07Durability, Deterioration, and Service Life
This domain tests deterioration mechanisms and whether you can convert an exposure condition into concrete requirements and a defensible service-life estimate rather than simply specifying higher strength. Chloride-induced corrosion: chlorides reach the steel, depassivate it and the steel corrodes with volume expansion that spalls cover.
306 words, about 2 min08Construction Practice, Inspection, and Quality Control
This domain tests the field side of concrete: what to inspect, how often to test, which records prove compliance, and how to handle nonconformance without compromising the structure. Before placement, review mix designs, mill certificates, placing drawings, formwork and shoring design, and curing plans.
311 words, about 2 min09Repair, Rehabilitation, and Forensic Evaluation
This domain tests diagnosis and repair strategy: how to survey a deteriorated structure, how to select a repair compatible with the substrate, and how to build a defensible root-cause argument rather than a plausible story. Use a cover meter for reinforcement depth, half-cell potential per ASTM C876 (readings more negative than about minus 350 mV against a copper-copper sulfate electrode indicate high corrosion probability), phenolphthalein to map carbonation depth, chloride profiles by ASTM C1218, ultrasonic pulse velocity, ground-penetrating radar and petrography per ASTM C856.
