required in the basic 'design. Assuming the sand in the example to have a 4.0% . free moisture, the corrected sand scale weight is found by multiplying SSD weight. of sand by one plus %free moisture in decimal form. Therefore, 1055 lbs. (SSD} multiplied by 1.04 equals 1097 lbs. moist sand scale weight.
Quality Management System for Ready Mixed Concrete Companies
Prior to batching the first load of concrete each day, component materials must be loaded into the plant; trucks must be in place; and instructions must be communicated to the concrete batch personnel and/or computer. Once a day the Plant Manager, or delegate, should perform a walk through inspection of the concrete plant.
