This guide identifies the various classes of floors based on use, construction design details, necessary site preparation, concrete type, and other related materials. In general, characteristics of the concrete slab surface and joint performance have a powerful impact on the serviceability of floors and other slabs.
Plastic sheet test (ASTM D 4263) and calcium chloride test (ASTM F 1869) are used to measure concrete moisture and vapor. The former provides qualitative measure whereas the latter gives quantitative result.
The quality of a concrete floor or slab is highly dependent on achieving a hard and durable surface that is flat, relatively free of cracks, and at the proper grade and elevation. Properties of the surface are determined by the mixture proportions and the quality of the concreting and jointing opera-tions.
How to Test Moisture in Concrete Floors 1. Install Smart Logger and Log 48 Hours Before Testing. Use one per zone of conditioned space where concrete will be tested. 2. Use Concrete Moisture Meter to Identify Areas with the Highest Comparative Moisture. Use only on smooth surfaces.
Concrete Construction and Standard A23.2-14 Test Methods and Standard Practices for Concrete describes the standards and test methods respectively, this document is intended as a guideline to provide additional commentary regarding best practices which can be used for field testing and sample collection.
17 Ιουλ 2023 · A definitive test that measures the amount of moisture released from the concrete requires a calcium chloride kit or a relative humidity meter. Testing with either method will tell you precisely how much moisture is present, making it possible to choose surface flooring that is appropriate.
This design guide presents a method for assessing floor vibrations guaranteeing the comfort of occupants. This document is based on recent research developments (RFCS-Project “Vibration of floors”). Guidance for the structural integrity, given in this document, is based on common approaches.
