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
1.2
Fresh concrete is tested and analysed to determine the proportions of a
concrete mix.
Range
1.3
workability tests include but are not limited to – slump test,
compacting factor test, vebe consistometer test, flow test.
analysis methods include but are not limited to – buoyancy, rapid
analysis machine, pressure filter.
Methods of testing hardened concrete are described in terms of testing for
saturated density, compressive strength and tensile splitting strength and
flexural strength.

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.
