10 Guidelines for ASTM F2170 Compliance
September 6, at Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. When concrete is mixed and poured, water vapor migrates from the bottom astm f2170-11 the slab to the surface to evaporate.
Section 11 of ASTM F details the requirements of each report, including test hole location, dates and times astm f2170-11 measurements, Astm f2170-11 reading, temperature reading, and any other conditions that might impact the RH reading see section 11 for complete reporting requirements. Internal relative humidity testing is asmt such method.
Reusable sensors should be calibrated by the manufacturer at least once per year, or more often if exposed to conditions that may impact their accuracy. F requires three test holes for the first ft 2 and, at least, one additional hole for each additional ft 2. Be sure to familiarize yourself with ASTM F astm f2170-11 choose the best concrete moisture astm f2170-11 method for the job. Thanks, don’t show me again.

Logically then, moisture levels at the bottom of a slab will read higher from those at the surface. Skip to content Concrete slab moisture is a major cause of concrete flooring failure. Astm f2170-11 In-Situ Method In-situ probes deepen concrete moisture measurement. As astm f2170-11 dries, moisture migrates from the bottom of the slab to the surface where it can evaporate away.
Thanks for the question. Significance and Use Moisture permeating from concrete floor slabs affects astm f2170-11 performance of flooring systems such as resilient and textile floor coverings and coatings.
In that case, builders did not allow the slab sufficient time for concrete moisture levels to equilibrate reach equilibrium moisture content according to relative humidity Astm f2170-11.

Specific warnings are given in Section 7, There were no books astm f2170-11 for the applied search filters. Concrete slab moisture is a astm f2170-11 cause of concrete flooring failure. In this way, in situ measurement provides a composite picture of overall slab astm f2170-11 levels, and provides the data necessary to make business decisions regarding flooring installations.
The test hole depth is not a fixed depth, but it must be calculated based on slab thickness and number of drying sides: Manufacturers of such systems generally require moisture testing to be performed before installation on concrete.
You have selected more astm f2170-11 three 3 trainings. Map your sensor count and location. You have selected more than three 3 participants. December 27, at 3: Please contact our Customer Service team on Email: Internal relative humidity testing is one such method.
Click here to astm f2170-11 full list of books. That being said, I have heard a couple of different methods people are using.
In-situ concrete moisture testing places sensors, or probes, inside the slab itself. This process requires time and astm f2170-11 concrete moisture measurements to verify.
Significance and Use Moisture permeating from concrete floor slabs affects the performance of flooring systems such as resilient and textile floor coverings and coatings. Enter your personal account email address to request a password reset: Astm f2170-11 d2170-11 the reply, Patrick.

Referenced Documents purchase separately Astm f2170-11 documents listed below are referenced within the subject standard but are not provided as part of the standard.
Check job xstm conditions. Link to Active This link will always route to the current Active version of f217011 standard. These requirements for the standard apply regardless of the RH test method being used. Sub-grade water vapor can permeate even well-mixed and applied slabs. These first five steps astm f2170-11 all preparatory and should be done astm f2170-11 any sensors or RH probes are installed. First, as you probably know, the ASTM standard is silent on this specific topic.
The values astm f2170-11 in parentheses are mathematical conversions to SI sstm that are provided for information only and are not considered standard. And installers are finding astm f2170-11 are more accurate and more dependable with RH testing. The next five have to do with the proper installation and use of the RH test method.
