1. The materials shall be measured in conformance with the requirements of the ASTM Specification C94. Weight-batch apparatus for conventional, type mixers shall also meet the same requirements. 2. Bulk cement shall be. weighed on scales having a degree of control and accuracy such that the delivered weight shall be correct within one percent. The scale and weight hopper shall be separate and distinct from those used for other materials. Cement may be batched on a bag basis; the weight of a bag of Portland Cement (U.S.) shall be taken as 94 pounds and only whole units are to be used with this method.
3. Aggregates shall be weighed or; scales having a degree of control of accuracy such that the delivered weights are correct within two percent. /'"■oisture, both free and absorbed, shall be corrected for and the free moisture shall be taken into account when dispensing the mixing water. 4. Water shall be measured by volume or weight with an accuracy and control within a one percent tolerance. 5. When, the outdoor temperature is below 40°? or is likely to fall below 40°F during the 24-hou.r period after placing, adequate equipment shall be provided for heating
