GBT25993-BSplitting and tensile testing device for permeable pavement bricks Concrete pavement brick tensile fixture Road tile splitting tensile fixture Splitting tensile fixture Splitting tensile pressure plate

1、 Product Introduction:

This equipment is suitable for the test method of splitting tensile strength of permeable pavement bricks. The workbench has a suitable area and a smooth surface made of hard material. It can only be put into use after passing the verification with a level ruler. comply with standardsGBT25993Requirements for permeable pavement bricks and permeable pavement panels.

2、 Technical parameters:

1The contact surface radius is75±5mm

2Thickness of gasket4±1mm

3Width of gasket15±1mm

3、 Sample processing:

1The entire pavement brick is used as a test piece. When there are irregular irregularities or bumps on its side, the base needs to be cut or polished to make the side of the test piece flat.

2The stress and shear force of the splitting tensile test of permeable pavement bricks should meet the following conditions

aFor rectangular permeable bricks, the stress section should be parallel or perpendicular to each side of the specimen.

bThe force is intercepted and passes through the centroid of the top surface of the permeable brick.

cThe length of failure of the stress sectionLIt should be as long as possible.

3Use crayons and steel rulers to draw the position lines of the stress section on the top and bottom surfaces of the pavement bricks.

4Grind a line with a width greater than20mmThe upper and lower surfaces that are required to be ground are parallel, and are verified on the workbench using a level ruler and a steel gasket. The grinding depth should be as small as possible. For road tiles with a flat top surface, the one-way grinding depth should not exceed2mmThe grinding depth of the permeable brick surface layer with concave convex non planar layers can be greater than2mm.

5Measure the thickness of the specimen at two loading points using a vernier caliperTMeasure the width of the loading area with a steel ruler.

6Immerse the specimen in（20±5）In water at ℃, （24±3）hAfter removal, wipe off the surface moisture and immediately start the experiment.
