ASTM C230/C230M-21 PDF Download

The ASTM C230/C230M-21 standard describes the requirements for the flow table and accessory apparatus used in flow tests for consistency of mortars in tests of hydraulic cement. The flow table is made up of a rigid iron frame and a circular rigid table top, both of which are described in detail in the specification. The specification also discusses the conical mold used for casting the flow specimen and the caliper used for measuring the diameter of the mortar after it has been spread by the flow table.

The purpose of this standard is to provide guidelines for the design and construction of the flow table and accessory apparatus to ensure accurate and consistent flow tests for hydraulic cement. The flow tests measure the consistency of mortars, which is an important property in determining the workability and performance of hydraulic cement.

It is worth noting that the specification includes a drawing (Figure 1) for informational purposes only, which helps clarify the design of the flow table and accessory apparatus. This drawing is referenced in Note 1 of the standard.
