GBT32987-9Test device for permeability of concrete pavement bricksGBT32987Test method for performance of concrete pavement bricks

1、 Product Introduction

The permeability test device for concrete pavement bricks meets the requirements《GB/T 32987-2016The test method for performance of concrete pavement bricks "states that the columns are made of stainless steel material, and the upper and lower pressure plates are made of steel plates coated with high transparency organic glass tubes with electrostatic paint, with clear markings.

2、 Product Information

Applicable specimen size:100×200×50mmor100×200×60mm

Scale tube size: inner diameter60mm±2mmheight300mmabove

Bottom plate hole area:50%above

3、 Operating instructions

1Stand the sample sideways in the water tank(This set of instruments does not include a sink)The interval between the samples shall not be less than20mmThe injection temperature is10~30°CThe water level should be about higher than the sample when soaked in water20mmSoak24HTake the sample out of the water and use a sponge or a wrung out wet towel to wipe off any water adhering to the surface.

2Place the specimen in the middle of the upper and lower pressure plates, place a rectangular silicone pad on the upper part of the specimen, and tighten it with a wrench6A nut.

3Inject a temperature of into the glass cylinder10~30°CThe water, in1MINAdd water to the glass cylinder inside200mmHigh.
