Advanced Concrete and Aggregates
Start Date:May 10, 2021
- To develop in-depth understanding of the influence of concrete components and service environment on its characteristics and performance.
- To provide in-depth review of mechanisms of concrete deterioration and to identify effective measures (both material and structural type) that promote durability
- To review most recent advancements in cement and concrete technologies.
- To integrate research and learning.
- To improve critical thinking as well as written and oral technical communication skills
This course will cover the physico-chemical and engineering properties of concrete at an advanced level by examining the influence of constituent materials (cements, aggregates and admixtures) on the properties and behavior of fresh and hardened concrete under various types of physical and chemical environments
- Physicochemical Properties of Cements and their Hydration: types of cements, influence of compound composition, heat of hydration, effects of alkalis, strength of cement paste.
- Microstructure of Hydrated Cement Paste: volume of hydration products, role of water in hydrated gel, porosity.
- Admixtures: benefits of admixtures, types, dosage, admixture-cement compatibility
- Properties of Aggregates: physical properties, reactivity, gradation requirements, lightweight aggregates.
- Fresh Concrete : Workability, importance of mixing, pumping, vibration, analysis of fresh concrete.
- Hardened Concrete: strength, aggregate-paste interface, maturity, bond to reinforcement, elasticity, creep, shrinkage, fracture, fatigue strength, nondestructive testing.
- Durability: diffusion, absorption, freezing and thawing deterioration, carbonation, sulfate attack, alkali-silica reaction, effects of deicing chemicals, corrosion of reinforcement.
- Supplementary Cementitious Materials: types, reactivity, effects on concrete properties
- High-Performance Concrete: principles, design methods, production, and testing Recent developments in Concrete Science and Technology - Self compacting concrete, nanotechnology.
