According to Baidu Library, the mold of impervious test block is usually made of cast iron, and its characteristics of high hardness, wear resistance and corrosion resistance can ensure that the mold will not be deformed after long-term use. Mold size:
(1) overall dimensions: length× width× height =150mm×150mm×150mm.
(2) Inner hole size: length× width× height =100 mm×100 mm×100 mm. ..
(3) Wall thickness: about 10mm, so as to ensure that concrete does not leak slurry during pouring.
(4) Bottom design: The bottom is plane design, which needs to be thickened to ensure that the concrete will not be deformed during pouring.
The weight of impermeability test block mold is usually about 16kg, which is convenient for testers to carry and operate.
