Lateral Formwork Pressure for Self-Compacting Concrete—A

2.1. Concrete Mix Design Concrete mix design is an important factor affecting the formwork pressure [26,35]. Aggregate grading, cement type, type of chemical admixtures, amount of superplasti-cizer, and water to cement ratio are certainly some of the most crucial parameters affecting the maximum formwork pressure [12].

Materials | Free Full-Text | Study on Adaptability of Test

To ensure the quality of concrete construction, the workability of fresh mix measured by rational test methods is critical to be controlled. With the presence of steel fibers, whether the test methods and evaluation indices of fresh self-compacting concrete (SCC) are adaptable for self-compacting steel fiber reinforced concrete (SFRC) needs to be systematically verified.

Methods of Testing Self Compacting Concrete Workability

May 09,  · When the flow of concrete stops the height of the concrete mix (h 2) at the end of the flow is measured along with height (h 1) in the vertical box next to the obstruction. The ratio h 2 /h 1 is a measure of the passing ability of self-compacting concrete (SCC). The blocking value for self-compacting concrete (SCC) should be between 0.80 to 1.0.
