AS 1012.3.5:2015 PDF Download

AS 1012.3.5:2015 standard provides guidelines for testing the consistency of self-compacting concrete (SCC). The standard specifies the procedure for determining the slump flow, which is the measured diameter of spread when the flowing concrete exceeds 500 mm. It applies when the nominal size of the aggregate used in the concrete does not exceed 20 mm.

Additionally, the standard outlines the method for measuring the T500 time, which refers to the time it takes for the slumping and flowing SCC to reach a diameter of 500 mm. This parameter helps assess the workability and flowability of the concrete. The standard also includes guidance on the J-ring passing ability, which measures the ability of SCC to flow through a J-ring.

Furthermore, the standard covers the assessment of the stability and resistance to segregation of SCC. This is important in ensuring that the concrete maintains its consistency and homogeneity during transportation, placement, and curing.

It's important to note that this standard may involve hazardous materials, operations, and equipment. Therefore, proper safety precautions should be followed when conducting the tests outlined in this standard.
