Obtain the sample after a minimum of 1/2 m3 (1/2 yd3) of concrete has been discharged. Perform sampling by passing a receptacle completely through the discharge stream, or by completely diverting the discharge into a sample container. Take care not to restrict the flow of concrete from the mixer, container, or transportation unit so as to cause segregation. These requirements apply to both tilting and nontilting mixers.

Procedure for Concrete Sample Preparation | Concrete

Compaction is the removal of air from fresh concrete. Proper compaction results in concrete with an increased density which is stronger and more durable. Concrete is placed in the mold, in three layers of approximately equal volume. Each layer is compacted with 25 strokes with the rounded end of the rod (as specified by ASTM standards).

This paper numerically investigates the required superplasticizer (SP) demand for self-consolidating concrete (SCC) as a valuable information source to obtain a durable SCC. In this regard, an adaptive neuro-fuzzy inference system (ANFIS) is integrated with three metaheuristic algorithms to evaluate a dataset from non-destructive tests. Hence, five different non-destructive testing methods
