Concrete aggregates awareness


Overview
This training standard will enable trainees to develop their knowledge of aggregates, how and when they’re used, and the practical impacts and consequences of using different aggregates.

CITB has developed this standard in discussion with industry

Duration

Minimum 1 day of 6 learning hours

Purpose/Scope

This training standard will enable trainees to develop their knowledge of aggregates, how and when they’re used, and the practical impacts and consequences of using different aggregates.  

Scope:

  • different types of aggregates
  • impact on value
  • quality dimensions
  • environmental impacts
  • sustainability
  • do's and don'ts.

Occupational relevance

Training delivered against this standard would be relevant to the following occupational groups:

  • operative and craft
  • supervision
  • management and leadership.

Candidate pre-requisites

There are no candidate pre-requisites as part of this standard. However experience of using and testing 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
  • a verifiable CV.

Delivery

Delivery may be in an on or off the job environment.

All materials and equipment must be of a suitable quality and quantity for candidates to achieve learning outcomes, and must comply with relevant legislation.

The class size and candidate/instructor ratio must allow training to be delivered in a safe manner and enable candidates to achieve the learning outcomes.

The following delivery methods may be used in the delivery of this standard:

  • classroom
  • a blend of classroom and e-learning

This standard is considered to contain 51% or more theoretical learning.

Assessment

Methods of assessment considered appropriate for training delivered against this standard are: For the successful completion of training, the trainer must be satisfied that the candidate has achieved all of the learning outcomes. 

Quality assurance

Quality assurance against this standard will require initial approval of the training organisation and their content mapped to the standard.

CITB will also conduct an approval intervention, either desk-based or centre visit, to ensure the training organisation can meet the requirements of the training standard.

Approved training organisations (ATOs) will be required to present information on records of training and assessment upon request to CITB for desk based analysis. They will also be visited annually by the CITB quality assurance team.

Renewal/refresher

Non-mandatory refresher every 5 years.

Approval date

November 2018

Review cycle

Either on request or 3 years from approval date.

Learning outcomes

List some of the do’s and don’ts

DO use aggregate that's in compliance with ASTM C 33, "Standard specifications for concrete aggregates." 

DON'T exceed limits for deleterious material content in fine and coarse aggregates. Some specifications may require more stringent limitations.

DO monitor moisture contents of coarse and fine aggregates on a regular basis to promote batch-to-batch consistency and uniformity. https://www.astm.org/Standards/C566.htm

DO make sure stockpiles are properly managed.
