Moisture Measurement for aggregates and sand using Hydronix ...

Modern plants can weigh aggregates with an accuracy of up to ± 0.5%. If the amount of moisture in a batch of sand or aggregates varies from between 2% to 10% then this will affect the accuracy and proportions of the weighed materials since water is effectively being weighed and not dry materials.

Effects of moisture variation on concrete mixes and ...

Table 2 shows the same mix design made with a moisture variation of 0.2%. This gives a total water value of 179kg which gives the actual water/cement ratio as 0.51. Again if the calculation is reversed to ive the correct water/cement ratio, it is shown that the g total cement needed is 179/0.5 = 358kg, so an extra 8kg of cement is needed.
