Concrete Technology

Aggregates for concrete and mortars. Mineral binders: cements, lime and gypsum. Mixing water for concrete. Additions and admixtures for concrete. Concrete according to the standard EN 206-1 Concrete – Part 1: Specification, performance, production and conformity. Properties of fresh and hardened concrete and their testing. Concrete mix design calculations. Technological processes in concrete production.

Description:

The purpose of this module is to: introduce classification, properties and testing of technical properties of concrete constituents, fresh and hardened concrete; teach how to select proper concrete constituents and design concrete composition; describe processes in concrete production.

Requirements:
