Abstract
The weight of aggregate for preparing concrete and mortar is measured while the aggregate is immersed in water contained in a container. The water in the container is discharged and the water in the interstice in the aggregate is also removed. Thereafter the weight of the aggregate is measured again. These measured values of the aggregate are used to determine the quantity of water to be added to the aggregate when it is used to prepare concrete or mortar.
