Construction & Electrical Materials Distribution: 014 - Aggregates & Blocks
This module examines in detail the products involved in construction, including both their properties and application. This area is fundamental to building work, but is often overlooked because it requires specialist product knowledge. However, even though it is usually the professional who orders these items, sales are often considerable so it is important to have a sound working knowledge of the specifications and developments in this area.
