A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel-reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving (see below). [1] [2]
Pouring a concrete foundation (aka slab) costs between $5,000 and $40,000, depending on your home’s square footage. An average size home’s foundation costs around $10,000. You can expect ...
The advantages of this approach are the further reduction of manual labour time and cost per unit area of slab and a simple and systematic building technique. The disadvantages of this approach are the necessary high lifting capacity of building site cranes, additional expensive crane time, higher material costs and little flexibility.
Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of construction allows for a large portion of the work to be completed at ground level, negating the ...
In the simplest case, where cost is linear in output, the equation for the total semi-variable cost is as follows: [6] = + where is the total cost, is the fixed cost, is the variable cost per unit, and is the number of units (i.e. the output produced).
Average variable cost (AVC/SRAVC) (which is a short-run concept) is the variable cost (typically labor cost) per unit of output: SRAVC = wL / Q where w is the wage rate, L is the quantity of labor used, and Q is the quantity of output produced. The SRAVC curve plots the short-run average variable cost against the level of output and is ...
Slabs are one of the greatest consumers of concrete in many buildings, [14] so reducing the slab mass can make a relatively large difference to the environmental impact of a building's construction. Biaxial slabs may be marginally cheaper than solid slabs, partly due to the lower mass.
Marginal cost (MC): Marginal cost is obtained from the additional cost that results from increasing output by one unit. It is the additional cost per additional unit of output. [7] Cost curves: It is the graphical presentation of the costs of production as a function of total quantity produced [8] [9]
