In continuing the previous study, the author reports on the testing of the concrete. The tests of the stored cement were carried out about the 3 zones in the bags, i.e. outher zone, next and central parts. In conclusion, the compressive strength of the concrete of the outer zone showed extraordinary decrement. The decrement of the strength of the concrete was more than that of the mortar by the ordinary method.
