Specifications for Structural Concrete



   Course overview

Decisions regarding the choice of constituent materials and mix proportions are frequently left to the contractor.  Concrete specifications are notoriously very brief and seldom go further that a compressive strength, although the number of possible properties is huge.

An understanding of the requirements of a particular structure need to be assessed and specified, then properly interpreted by the contractor in order to price a tender correctly and construct a high quality structure.

The properties of concrete are variable and change with structural and environmental conditions.  A workshop will be conducted as part of the course where different types of structure and environments will be assessed and their needs defined.

Course description

The contents of this two-day course will be of great interest to structural designers and contractors as the parties responsible for the design of concrete mixes and selection of materials is poorly defined.  The course will discuss the most important properties of concrete from a practical structural perspective and assist attendees with the identification of the concrete requirements and their achievement in terms of the specification.

Course outline

·         Selection of constituent materials to achieve concrete properties - aggregates, cement, elastic modulus, admixtures and water

·         Site processes on concrete - temperature, plastic shrinkage, batching, mixing, transport, placement, compaction

·         Processes in the green state - curing, finishing

·         Properties of concrete in the final hardened state - characteristic strength, statistical margin, testing in compression, flexural strength, elasticity & creep, abrasion resistance, drying shrinkage, durability

·         Formwork and falsework - design, effect of materials, effect of compaction, striking of formwork, care of formwork, types of formwork precautions

·         Common concrete defects that affect structural performance and their avoidance - different material interface, thermal cracking, moisture and thermal expansion and contraction, distribution steel, mechanical and chemical attack

·         Case studies workshop where different types of structure and the requirements of the concrete will be discussed between delegates

Course outcomes

·         An ability to foresee the requirements of the concrete material during the design stage and specify accordingly

·         Expertise in the production of concrete to suit the requirements of a specification

·         Skills in the identification of the cause of defects and the most probable consequences

·         Understanding the importance of constituent material selection and its effect on concrete properties

Who should attend?

·         Designers of reinforced concrete structures who wish to understand the properties of the materials they use

·         Constructors of reinforced concrete structures who interpret the needs of a specification and translate that into the correct material selection and mix design with a high standard of workmanship

·         Supervisors and project managers responsible for the quality control of the project

·         Client and government bodies who want to understand the design and construction process for which they are financially responsible
