This training course covered various topics related to concrete engineering including: 1. The main materials used to produce concrete such as cement, aggregates, water, and additives. 2. Factors that influence the strength and properties of concrete including water-cement ratio, curing methods, and mix design. 3. Laboratory testing procedures and standards for evaluating concrete strength and quality. 4. Non-destructive field testing techniques to assess concrete structures. 5. The importance of proper mixing, placing, compaction and curing of concrete to achieve the desired strength and durability of the final structure.
