Pricing Concrete Work

The concrete work in a project usually holds a high-end cost in terms of cost and value of the work. It becomes an important step in calculating the cost associated with concrete while preparing the project scale. The cost of making concrete depends on the cost of building materials, mixed materials, labor, and machinery. A concrete contractor builds structures from concrete, usually managing all the steps of the process from assembling ingredients to building a holding structure and preparing the mixture. This person or team oversees the delivery and unloading of goods to ensure that they are done properly. Nowadays, most of the concrete in the United States comes from manufacturers working abroad, usually with branches and plants within the provinces. Contributions can range from pre-mixed concrete to basic ingredients, the consumer company then mixes it. Many American-based concrete companies, however, offer concrete products, such as ballads, bricks, countertop, concrete pipe, and building products, as well as concrete construction and installation materials. This article covers both types of suppliers for this set of building materials.

You want to increase the sustainability of a concrete mixture by replacing 35% of the portland cement by mass with a locally available natural pozzolan that can be used in place of ordinary portland cement (CEMPOZZ). The quantity of cement in the concrete mixture is 620 lb/yd3. You can assume that the specific gravity of portland cement and CEMPOZZ are the same for this problem. What is the quantity of CEMPOZZ for the mixture? Round to the nearest whole number and do not include units when entering your answer.
