The first chart shows that fixed costs remain $50,000 at all production levels from 100 units to 1,000 units. The second chart shows that the fixed cost per unit decreases as production increases. Hence, when 100 units are manufactured, the fixed cost per unit is $500 ($50,000 100).
Plastic Roofing Cements. What is âPlastic Roofing Cementâ? Plastic Roofing Cement is composed of asphalt, fiber, solvent vehicle and sometimes rubber polymer as well as. water displacement additives.
Plasticizers (often called super-plasticizers) are chemical admixtures which cut the electrostatic attraction in cement. This allows the cement to become more evenly dispersed in the concrete mix, and creates a stronger concrete as a result. Another significant benefit to using a super-plasticizer is the increased workability of the concrete. The mix doesnât stick together so much; it is more fluid and liquid, without adding more water (too much water weakens concrete substantially).
