E – 1323 Tropical Engineering: Concrete, Wood, Metals

Description

This course provides an introduction to the application of concrete, wood and metal materials and products in construction for tropical climates where humidity, weather and seafront locations are considerations. Concrete materials, reinforcement, accessories, curing, structural precast concrete, prestressed concrete, and cast-in-place concrete are discussed. Concrete masonry units (CMU), both solid and hollow, used in general construction are included. Structural steel and metals of a generic nature are considered but not specific products. Wood construction covers rough carpentry, heavy construction timber, finish carpentry, plywood, wood treatments, prefabricated structural wood and its uses and prefabricated plastics. Rough hardware, particle board and treatment and use are also included.

This course will give structural and civil engineers and other design and construction professionals an introduction to tropical engineering using wood, metal and concrete construction materials and products.

• Learn the importance of minimizing the salt content of both the water and aggregates (especially coral) used in the concrete mix;
• Learn how the density of aggregates affects concrete strength, cement and water content, workability, and porosity of the concrete, all of which indirectly influence steel corrosion;
• Learn how air-entraining agents are used to improve workability of concrete;
• Learn about the precaution to be observed when using galvanized reinforcement;
• Learn the significance of water infiltration of concrete masonry units in the tropics;
• Learn why it is important to avoid corrosion of metals caused by galvanic action between two dissimilar metals; and
• Learn how to base selection of wood for exterior lumber and timber on strength and treatability.
