Explanatory notes

    Legislation and publications relevant to this unit standard include: Health and Safety in Employment Act 1992;

    NZS 3111:1986 Methods of test for water and aggregate for concrete; NZS 3112:1986

    Methods of test for concrete Parts 1, 2, 3, and 4, available from Standards New Zealand (http://www.standards.co.nz).

Outcomes and evidence requirements

Outcome 1

Test fresh and hardened concrete.

Evidence requirements

    1.1 Methods of sampling fresh concrete are described in terms of the workability

    tests used.

    Range workability tests include but are not limited to slump test,

    compacting factor test, vebe consistometer test, flow test.

    1.2 Fresh concrete is tested and analysed to determine the proportions of a

    concrete mix.

    Range analysis methods include but are not limited to buoyancy, rapid

    analysis machine, pressure filter.

    1.3 Methods of testing hardened concrete are described in terms of testing for

    saturated density, compressive strength and tensile splitting strength and

    flexural strength.

    Range testing methods include but are not limited to cubes, cores,

    flexural strength tests, surface absorption test, compression

    testing.

    1.4 Hardened concrete is tested to determine density, strength and flexibility.

    1.5 Fresh concrete is tested to determine air content and yield.

Outcome 2

    Outline the requirements for specialist tests for concrete.

Evidence requirements

    2.1 Methods of sampling aggregates in concrete are described in terms of

    determining aggregate properties.

    Range aggregate properties include but are not limited to flakiness, clay,

    silt, dust, density, water absorption, voids, bulking, moisture

    content;

    sampling methods include but are not limited to sieve analysis,

    field settling test, pycnometer, calculation, over-drying method,

    siphon-can method, modified drying method, ‘speedy’ method.

    2.2 Non-destructive tests for hardened concrete are described in terms of methods

    and purposes.

    Range methods and purposes include but are not limited to rebound

    hammer, ultrasonic pulse velocity, electromagnetic covermeter,

    gamma radiography, internal fracture test.

    2.3 Core testing is described in terms of procedures for drilling, preparing and

    compression testing of cores.

    Range core testing includes but is not limited to calculating in-situ cube

    strength, actual and potential strengths.

Consent and Moderation Requirements (CMR) reference 0048

    This CMR can be accessed at http://www.nzqa.govt.nz/framework/search/index.do.

Please note

    Providers must be granted consent to assess against standards (accredited) by NZQA, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment.

    Industry Training Organisations must be granted consent to assess against standards by NZQA before they can register credits from assessment against unit standards.

    Providers and Industry Training Organisations, which have been granted consent and which are assessing against unit standards must engage with the moderation system that applies to those standards.

    Requirements for consent to assess and an outline of the moderation system that applies to this standard are outlined in the Consent and Moderation Requirements (CMR). The CMR also includes useful information about special requirements for organisations wishing to develop education and training programmes, such as minimum qualifications for tutors and assessors, and special resource requirements.
