A simply supported concrete slab given the section depth is 100mm, concrete grade is C30 and reinforcement grade is HPB300. The span of slab is 19=2.38m. The live load applied on the slab is ge=2kN/m2 and the dead load include: 1. Its self-weight given concrete (include reinforcement) bulk density is 28kN/m3 2. Terrazzo floor and fine stone cushion layer is 30mm(bulk density is 22kN/m) and the ceiling plaster mortar is 12mm(bulk density 17kN/m²).

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.
