J Ring Flow Test
Evaluating gap permeability! Introducing the workability evaluation criteria for high-flow concrete.
The "J Ring Flow Test" is an evaluation method for the workability (material separation resistance, fluidity, and gap passing ability) required for high fluidity concrete using high-performance AE water-reducing agents containing thickening agents, with a target slump flow of 500 mm or more. By installing a J ring in the conventional slump flow test, the gap passing ability is evaluated based on the obstacles provided by the J ring. 【Evaluation Contents】 ■ Material Separation Resistance ■ Fluidity ■ Gap Passing Ability *For more details, please refer to the PDF document or feel free to contact us.
