I have found that most contractors use 2500-3000 psi concrete for driveways. Increasing the concrete thickness to 5" and adding rebar increases the compressive, tensile, and flexural strength of the driveway. If you look closely at the invoices, you'll see I get charged $105.00 per yard for 3500 psi 3/4 aggregate mix and $114.50 for 3500 psi 3/8 aggregate mix. Depth (Inches) Tension Load (Pounds) Allowable Bond Strength (Pounds) UBC Allowable Tensile Stress Soil directly under the footing takes the greatest load, and therefore should be thoroughly compacted. GFRC can be cast into thinner sections than precast, and is therefore as much as 75% lighter than similar pieces cast with traditional concrete. For smaller to medium equipment - cars, smaller trucks, nominal rack loading, I used a 5" slab with 4000 psi concrete, fiber reinforcement, and air entrainment. Weight should not exceed 40 lbs/sq ft on an undetermined 4-inch slab. Concrete compressive strength requirements can vary from 2500 psi (17 MPa) for residential concrete to 4000 psi (28 . The answer depends on a few things which you will need to provide: - The strength of the concrete mix. Find nearby slab and foundation contractors to help with your footings. . I can recall in the early 1950's when 2000 or 2500 psi concrete was used in suspended slabs and beams. Depending on the percentage of the portions in the mix , a fully cured slab of concrete should have a compressive strength of between 2200-5000 psi. . The nominal strength of a rectangular section is the sum of concrete strength Vc and reinforcement Chapter 11 11.1The column shown in Fig. Add (1)+ (2)+ (3); 5. As you can see, heavy houses on weak soil need footings 2 feet wide or more. Concrete used in warehouses, factories, and other large-scale commercial properties often requires 4,000-5,000 psi. The compressive strength is calculated from the failure load divided by the cross-sectional area resisting the load and reported in units of pound-force per square inch (psi) in US Customary units or megapascals (MPa) in SI units. The concrete compressive strength must be at the specified minimum at the time of installation. Density *Area. Concrete that exceeds 5,000 PSI is used in special construction projects that require building materials that . Example. I received the concrete mix design shop drawing for a 4000 psi and report from the new structural engineer stating that the concrete section capacity is only 1% less if 4000 psi to be used instead of using 5000 psi. That will get you a live load capacity of 200 psf. P11-1 is made of 4000 psi concrete and Grade-60 steel. u is Poisson's ratio which is set to 0.15 in this module. To determine how thick concrete should be for an RV driveway, you have to consider the soil's bearing capacity, the heaviest load your RV will place on the concrete and the minimum thickness standard. the required square footing size and thickness. 2.) conclud- 973-970-3334.
