Introduction to the permeability test of permeable concrete using the constant water level method established by the Geotechnical Engineering Society.
This test follows the constant water level method established by the Geotechnical Engineering Society. However, to verify and confirm whether the seepage flow follows Darcy's law, we will change the hydraulic gradient, measure the flow rate, and graph the results. To enhance the reliability of the permeability coefficient, we will perform a linear regression analysis based on the relationship between the hydraulic gradient and flow rate that is believed to be within the laminar flow region (i≦0.1, including the theoretical values of hydraulic gradient i=0 and flow rate v=0). 【Overview】 ■ Sample Type: Permeable Concrete ■ Sample Number: No.1 ■ Type of Cement Used: NP ■ Name of Admixture Used: Beacon + S *For more details, please refer to the PDF document or feel free to contact us.
