One of the major limitations of the F number system is that it does not control the surface regularity at joints. Because joints are statistical anomalies, the standard test method forbids measurements within 24 inches. The designer specifying by F number has two methods to accommodate the problem.The first solution is to locate joints at locations where surface regularity is not important. The second solution is to design specifications for the joints themselves.

The TR 34 tolerances for defined traffic floors

The TR 34 System divides defined traffic floors into three categories:

a)Superflat

b)Category 1

c)Category 2

For each category, the TR 34 System specifies limits for three properties:

Property 1 is the difference in elevation between two points 12 inches apart, measured in the direction of vehicle traffic. This is the levelness tolerance.

Property 2 is the difference in slope over 24 inches measured in the direction of vehicle traffic. This is the flatness tolerance. It is identical as the 24 inch curvature utilized in the F number system.

Property 3 is the difference in elevation between opposite points in the left and right wheel path, measured perpendicular to the direction of vehicle traffic. As with Property 1, it is a levelness tolerance. The TR 34 System specifies different values for Property 3 depending upon whether the distance between left and right wheel paths is more or less than 5 nominal feet

The Superflat category is intended for very narrow aisle warehouses where the highest standards are required. Category 1 is suggested for very narrow aisle warehouses where the vertical lift height is between 26 and 43 feet. Category 2 is for very narrow aisle warehouses where the vertical lift height is under 26 feet and the use of low rise, automatically controlled vehicles. No matter which category of surface regularity is specified, it is accomplished by measuring elevations on 12 inch centers.This is very similar to an F number survey, but with an important distinction. In an F number survey, the elevation profiles are made on the floor at random. With the TR 34 System, the survey measurements are made on the actual paths of the vehicles that will utilize the floor.

Improving the wear resistance of concrete floors by grinding with the SFG10E SURFACE GRINDER

Poor wear resistance can often be traced back to a surface that is weaker than underlying levels of the pour. This occurrence can result from bad finishing techniques, improper curing or early freezing.

Where surface weakness is a problem, grinding can be a solution. The process is similar to the early age technique. The grinding depth is typically 1/16 to 1/8 inch. A large project should not be attempted until a small test area has proven that the technique will produce the desired results. Usually only a square yard of floor is ground with the normal wear tests performed.

Repair costs can be minimized by grinding only those floor areas that accommodate traffic. For example, in a pallet rack warehouse, it may be necessary to grind only the aisle areas and not under any of the racks.The grinding process can adversely affect the surface regularity. Where specific properties are important, it may be necessary to survey the floor during the grinding process to ensure that flatness and levelness specifications are maintained.

Cleaning concrete floors to improve the wear resistance with the SFG10E SURFACE GRINDER

Clean concrete floors have a longer service life than dirty, poorly maintained floors. Loose debris produces three-bodied wear by allowing particles to roll between the traffic and the floor surface. With some types of debris, especially when lodged in vehicle wheels, wear can be immediate and severe.

The SFG10E SURFACE GRINDER can be utilized with a number of multi accessories to clean and extend concrete floor service life. The SCRAPE-R-TACH® floor coatings removal system readily removes food, oil and rubber accumulations from high traffic floor areas. The Clean Sweep™ silicon impregnated, rotary brushes along with a biodegradable detergent applied to floors removes ground in dirt and debris from shop and industrial floors.Dry diamond segmented discs and blocks can be utilized to remove surface imperfections.
