Concrete Slab Cost A typical concrete slab costs 4 to 8 per square foot with most homeowners spending between 535 to 617 per square foot or 113 to 126 per cubic yard for both materials and installation Your final cost will depend on the slabs size thickness and if you any special reinforcement such as wire mesh or rebar...
Concrete in the member represented by a core test shall be considered acceptable if the average equivalent cube strength of the cores is equal to at least 85 percent of the cube strength of the grade of concrete specified for the corresponding age and no individual core has a strength less than 75 percent...
Concrete strength also comes into play but most slab concrete is around 3000 to 4000 psi so it s not a major factor The tensile strength of concrete is typically taken as 10 to 15 of the compressive strength so only about 400 or 500 psi Compare that to the tensile strength of Grade 60 rebar which is 60 000 psi...
The quality of resulting concrete is much better than the site-mixed concrete ie both the hand mixed and machine mixed concrete Ready mix concrete is particularly useful on congested sites or in road construction where there is little space or no space available for a...

IS 456-2000 has designated the concrete mixes into a number of grades as M10 M15 M20 M25 M30 M35 and M40 In this designation the letter M refers to the mix and the number to the specified 28 day cube strength of mix in N/mm 2...
Mar 25 2018 0183 32 I d probably go 8 concrete and 1/2 rebar on 18 or 2 centers 4 000 psi mix If you ve got tracked equipment pouring railroad rails in the concrete is really nice like some other guys suggested with the top 3/8 just barely out of the concrete so you can still sweep it...
The concrete slab thickness is determined based on estimated wheel and axle loadings and soil subgrade design factors Table 54 shows the thickness of concrete needed for various axle loads Reinforcing schedules for a mixing and loading pad floor slab on grade with one layer of reinforcing are shown in Tables 55 alternate and 56...
