## Concrete Footing Size & Dimensions - Concrete Network

Source: Table 403.1; CABO One- and Two- Family Dwelling Code; 1995. More footing dimensions: Footing thickness - 8 to 12 inches; Footing depth - varies based on frost line and soil strength (some footings can be shallow, while other must be deep) ; Concrete Calculator - Figure out how much concrete you'll need for your footings.. You can look up the recommended footing size, based on the size

## PRECAST CONCRETE MANHOLES

s = unit compressive stress in the ring (pounds per square foot) H = depth of manhole, feet Using an allowable concrete stress of 45% of the minimum specified compressive strength of 4,000 psi, the allowable compressive stress would be 1,800 psi. Substituting this value for s yields the following: = 3.4 s H 1,800 = 3.4H then H = 530 feet

## Residential Foundation Design Options and Concepts

Concrete is a mixture of cement, water, sand, gravel, crushed rock, or other aggregates. Sometimes one or more admixtures are added to change certain characteristics of the concrete, such as workability, durability, and time of hardening. The proportions of the components determine the concrete mix's compressive strength and durability.

## Basics of Concrete Pavement Thickness Design

Concrete Properties Use average, in-field strength for design (not minimum specified) If specify minimum flexural strength at 28-day of 550 psi & allow 10% of beams to fall below minimum: STEP 1 Estimate SDEV: 9% for typical ready mix. SDEV = 550 * 0.09 = 50 psi STEP 2 S'c design = S'c minimum + z * SDEV S'c design = 550 + 1.282 * 50 S

## Sizing Up a Sump Pump

Only Pump 1 will be able to handle 18 gallons per minute. The other three pumps can't handle any more than 12 gallons per minute. Note that changing to a larger size of pipe in this case might lower the friction head enough to enable you to use a different pump (Pump 2 on the chart). Maintaining the Pump Periodically maintain your pump by
