Civil Engineering Materials

What you'll learn

• Interpret stress–strain curves, time and temperature effects, and test statistics, and explain how specifications, sampling and acceptance testing control material quality.
• Characterize aggregates by gradation, fineness modulus, relative density, absorption and durability tests, and correct batch masses for stockpile moisture.
• Explain how portland cement is made and hydrates, compare cement types, and describe the roles of supplementary cementitious materials and admixtures.
• Proportion a concrete mix by the absolute volume method, setting the required average strength and the w/cm from ACI 318 exposure categories.
• Test fresh concrete for slump, air, density and temperature, and plan placing, consolidation, curing and hot- and cold-weather protection, including maturity-based strength estimates.
• Evaluate hardened concrete by cylinder and core acceptance criteria and explain durability mechanisms: freezing and thawing, scaling, alkali–silica reaction, sulfate attack and chloride ingress.
• Relate steel production, chemistry and processing to strength, ductility, toughness and weldability, and review mill certificates against grade requirements.
• Explain the electrochemistry of steel corrosion, estimate section loss, and select coatings, galvanizing, weathering steel, cathodic protection or corrosion-resistant reinforcement.
• Describe asphalt binder behavior and aging, interpret performance-grading tests, and select a binder grade for a climate and traffic level.
• Calculate asphalt mix volumetrics, determine a Superpave design binder content, and interpret moisture, rutting, cracking and in-place density tests.
• Explain the anisotropy, moisture behavior, grading and durability of wood, estimate shrinkage, and compare engineered wood products including glulam and CLT.
• Compare materials by embodied carbon using EPDs, life cycle concepts and material indices, and recommend durable, lower-carbon material choices.
