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.
Claims24
A method of preparing aggregate to be utilized to prepare concrete or mortar, comprising the steps of:
- loading aggregate in a container;
- pouring water into said container to a level to completely immerse said aggregate therein;
- weighing aggregate while it is being immersed in said water to determine the volume of the aggregate;
- discharging the water from said container;
- and
- removing water remaining in the interstice of said aggregate to adjust said aggregate to at least a capillary state.
An apparatus for preparing aggregate to be utilized to prepare concrete or mortar comprising:
- a container having an aggregate loading opening at the top thereof;
- means for pouring water into said container;
- means for weighing aggregate while it is being immersed in said water;
- means for discharging water from said container;
- and
- means for removing water remaining in the interstice of said aggregate.
