SPT (Complete Set)

 spt equipment   1. Application and characteristic: CT-1 portable penetrometer is used to determine the frequency of layering penetration of foundation. It can used to determine the allowable bearing capacity of normal cohesive soil and plain fill based on the tested hammer bash No. (N10). It is suitable for substantial field working, is more economical and convenient than large type ones.   Allowable bearing capacity of  Cohesive soil (R)

No. of Hammer bash (N10)	15	20	25	30
(R) (t/m2)	10	14	18	22

  Allowable bearing capacity of  Cohesive plain fill (R)
