The effect of permeameter is to measure the seepage-resistant grade that concrete or soil cement etc. permeate slow material.Concrete
Impermeability seepage-resistant grade（P）Or infiltration coefficient represents.Seepage-resistant grade is with the standard specimen of 28d ages, is tried by standard
Maximum water pressure that proved recipe method can bear when being tested determines.GB50164《Standard for quality control of concrete》According to mixed
The maximum water pressure that solidifying soil test specimen can bear in impermeability test, by the seepage-resistant grade of concrete be divided into P4, P6, P8,
Five grades such as P10, P12.It is corresponding to represent when 4 test specimens do not seep water in one group of 6 test specimen during concrete impermeability test not
Same maximum water pressure.
But in permeable experimentation, bad due to sealing under high pressure effect, water is oozed out from test specimen periphery, often
Reseal.The method of sealing is that have in one layer of sealing material of test specimen side roller coating, currently used sealing material：1st, butter
Mix talcum powder；2nd, cement adds butter, its amount ratio is 2.5: 1~3: 1；3rd, silicon rubber.But three of the above method all cannot be fine
Solve the problems, such as leakage.
