3.2 Use in Laboratory
ConcreCem contains some ingredients in rather small quantities. As a dosage of ConcreCem rarely exceeds 1% by mass of cement, the amount of ConcreCem actually used in a mix is very small.
As a result of this when working with ConcreCem in the laboratory, and in order to have representative results from the laboratory tests, the minimum sample size (batch mix size) needs to be adjusted so that a minimum amount of ConcreCem that is used in the preparation of the batch mix in the laboratory is equal to or exceeds a minimum quantity of 40 gram/batch.
Figure 3.3 shows the laboratory preparation of samples and their eventual destructive testing.
