Introduction to concrete and its constituents


Overview
This training standard is an introduction to the constituents of concrete and their impact on the strength, durability, handling and placing of concrete.

CITB has developed this standard in discussion with industry

Duration

Minimum 1 day of 6 learning hours

Purpose/Scope

This training standard is an introduction to the constituents of concrete and their impact on the strength, durability, handling and placing of concrete.

Scope:

  • binders
  • aggregates
  • admixture
  • water
  • reinforcement including fibres
  • specification for strength, durability
  • rheology, handling and placing
  • batching
  • testing fresh and hardened concrete.

Occupational relevance

Training delivered against this standard would be relevant to the following occupational group(s):

  • operative and craft
  • supervision
  • management and leadership.

Candidate pre-requisites

There are no candidate pre-requisites as part of this standard. However a basic knowledge and experience of concrete would be beneficial.

Instruction/Supervision

As a minimum, course instructors must be able to demonstrate that, in relation to this standard, they have:

  • a train the trainer or instructional techniques course certificate
  • successfully completed training to this standard
  • at least 2 years relevant industrial experience

Approval date

November 2018

Review cycle

Either on request or in 3 years from approval date.

Learning outcomes

The candidate will be able to: Additional guidance to support learning outcome
List constituents
Describe effects on strength and durability Effects of changes in cement content and type,  water content, use of admixtures etc
Describe placing and handling of concrete in relation to consistence Pumping, skip, slip-form, chute sprayed etc 
Explain test methods and outcomes Test tolerances
