Concrete Floor Profiling Graph

Velocity versus time graph of a ball of mass 5 0 g rolling on a concrete floor is shown above.

Concrete floor profiling graph. We wanted it to be a quick check profiler for contractors to estimate their ff numbers. If your organization is interested in retiring some of your floor profiling equipment we might be able to help. 0 05 n this question is part of force and laws of motion. One of the biggest mistakes in gardening is failing to prepare the soil properly by loosening the soil and adding organic matter before planting gardeners can set themselves up for success.

Ideal for testing new large 10 000 sq ft slabs. The graphs below represent the motion of 5 different objects. Mechanical profiling is the method of choice. Pulled manually across the floor the f meter can measure up to 2500 linear feet 5 000 point elevation readings per hour a data collection rate 3 to 5 times faster than any other device.

Large or difficult surfaces will usually be mechanically profiled. For concrete polymer modified overlays. The f meter is the finest floor profiling instrument ever made. We ll be adding some more details here soon please check back.

F numbers provide architects and contractors a method of determining the flatness and levelness of a concrete floor slab. They are calculated using the standards set forth in astm e1155 which is the standard test method for determining f f floor flatness and f l floor levelness numbers the american concrete institute indicates acceptable ranges for flatness and levelness in aci 302 1 guide. Velocity versus time graph of a ball of mass 50 g rolling on a concrete floor is shown in the figure below. Fastest unit on the market.

The wood and concrete profiling provided by dustram certified contractors leaves the subfloor clear of dirt protruding staples screws or nails adhesive glues paint spills and even pet stains so it is ready for the brand new flooring the homeowner desires. Calculate the acceleration and the frictional force of the floor on the ball. The most effective reference tool for determining concrete surface profiles is the molded rubber comparator chips available from the international concrete repair institute. To create a desired concrete surface mechanical and chemical methods are used.

With the concrete sound and contaminant free all that s left is to adequately roughen the surface but to what degree. Contractors and manufacturers are split between roughening the concrete by mechanical profiling or acid etching. Claude besson explains the best techniques for concrete profiling. They also complete the whole job dust free at a comparable price for the value.

The truth is the first rolling device ever made to measure concrete floor profiles was developed by the face companies in the late 1980s and early 90s. Let us help you sell your used d meters and f meters. Some are graph of position x in the x. Some are graphs of velocity v in the x direction versus time.
