Concrete - Australia - Onorio

In Australia, two different types of concrete are specified and are:

– Normal-class;

– Special-class.

The Normal-class should have some attributes as defined in the AS 1379 and specified through some basic parameters. The parameters are:

– standard strength grade;

– slump at the point of acceptance;

– maximum nominal size of aggregate;

– method of placement;

– (if required) project assessment;

– (if required) level of air entrainment up to a maximum of 5%.

Concrete other than Normal-class shall be specified asSpecial-class and by strength grade (if applicable).

If the strength grade is applicable, the concrete shall be specified through some prefixes that are:

S, where compressive strength testing is required;

SF, where flexural strength testing is required;

ST, where indirect-tensile strength is required.

Where concrete is specified as Special-class and one of the exposure classification B1, B2, C1, C2 or U, as per AS 3600, is applicable, the following prefixes should be specified:

SB. for concrete in exposure classification B2;

SC, for concrete in exposure classification C1 or C2;

SU, for concrete in exposure classification U.

For the above SB, SC or SU the properties to be further specified shall include:

– the aggregate durability class, as per AS 2758.1;

– relevant requirements of AS 3600.

  1. Unquestionably imagine that that you stated. Your favorite reason seemed to be on the web the
    simplest factor to understand of. I say to you, I definitely get annoyed even as other
    people think about worries that they plainly don’t recognise about.
    You managed to hit the nail upon the highest and defined out the whole
    thing without having side effect , other folks can take a signal.
    Will likely be back to get more. Thanks
