§ 15.01.1120. Handling and measurement of materials.

Materials shall be stockpiled and batched by methods that will prevent segregation or contamination of aggregate and ensure accurate proportioning of the ingredients of the mix. Cement and aggregate shall be measured as follows:

1.

Cement. Cement shall be measured by weight or in bags of ninety-four pounds each. When cement is measured in bags, no fraction of a bag shall be used unless weighed.

2.

Aggregate. Aggregates shall be measured by weight. Mix proportions shall be based on saturated, surface-dry weights. The batch of each aggregate shall be the required saturated, surface-dry weight plus the weight of the surface moisture it contains.

3.

Water. Water shall be measured, by volume or by weight, to an accuracy within one percent of the total quantity of water required for the batch.

4.

Admixtures. Admixtures shall be measured within a limit of accuracy of three percent.
