HM-64 Self-Consolidating Concrete (SCC) Penetration Apparatus provides a rapid assessment of static segregation resistance of SCC. Poor segregation resistance can cause uneven aggregate distribution and blocking of flow around reinforcing bars or other obstacles, making the Penetration Apparatus useful during mixture development and before placing the SCC in the field.
The Apparatus is placed on top of an inverted slump cone filled with normal-weight, freshly mixed SCC. The penetration depth of the hollow cylinder is then used to correlate the degree of static segregation resistance. Apparatus conforms to ASTM C1712 (SCC Penetration Test) and includes a replaceable measuring scale marked in 1mm increments.
