Ff 35 floor flatness.

What does a specification for a floor flatness of 1 8 inch in 10 feet equal in f numbers. A self propelled laser guided screed can routinely create fl numbers of about 35 and higher. F f is measured as the curvature of the floor over a 2 foot interval. F f f l numbers have the following floor flatness classifications.

Concrete slab flatness slab flatness the degree of a slab s flatness is expressed by two numbers the ff and the fl together these are the f numbers they are the face floor profile numbers developed by allen face from 1978 to 1987. Ff25 fl20 moderately flat ff35. They describe a concrete slab s flatness ff and. The f f value is primarily a result of how good the finisher was at working the.

To quantify floor flatness using f numbers you begin by measuring the elevation differences d between points on the floor that are 1 foot apart along a straight line. Minimum subfloor flatness using astm e1155 ff sof f or a 10 3m. Take a grid of 2 foot intervals over the entire floor and put the values through an equation and you get the f f value as an indication of the waviness of the floor. Although there are no direct equivalents between f numbers and straightedge tolerances aci 302 construction of concrete floors and slabs gives the following table of approximate values.

Ff fl numbers have the following floor flatness classifications. Flatness is a measure of how bumpy the floor s finished surface is. F f this number is used to indicate the flatness of a random traffic floor. F f 25 f l 20 moderately flat.
