Equipment; flow table, Abrams cone, water bucket and broom. The cone filled with concrete, prior to lifting. The diameter of the resulting flow is measured. The flow table test or slump-flow test is a method to determine consistency of fresh concrete. Flow table test is also used to identify transportable moisture limit of solid bulk cargoes. [1]
The low-end test equipment is dominated by few large suppliers, notably Germany's Loviband and Merck, DelAgua & ITS Europe Water Testing of the UK who work globally, and US-based LaMotte. Major manufacturers of in-line equipment include Siemens and Danaher's Hach. Thermo Scientific and Waters are key producers of high-end test equipment. [38]
Environmental testing is the measurement of the performance of equipment under specified environmental conditions. [1] This can include the following: [2] [3] High and low extreme temperatures; Temperature cycling; Sand and dust exposure; Salt spray; High and low humidity; Wet environments; Deep water submersion; Corrosive material exposure ...
To ensure consistency and repeatability, the methods use in the chemical analysis of water samples are often agreed and published at a national or state level. By convention these are often referred to as "Blue book". [4] [5] Certain analyses are performed in-field (e.g. pH, specific conductance) while others involve sampling and laboratory ...
Epoxy moisture control systems can be applied over concrete with relative humidity levels up to 100%, and there are systems available on the market today that can be applied over concrete that is physically damp. In some cases, with the use of an epoxy moisture control system, floor coverings can be installed just 7 days after the slab is poured.
Water is a significant source of outgassing because a thin layer of water vapor rapidly adsorbs to everything whenever the chamber is opened to air. Water evaporates from surfaces too slowly to be fully removed at room temperature, but just fast enough to present a continuous level of background contamination.
Proceq SA of Switzerland is a technology company in the nondestructive testing space. The company name Proceq is taken from a combination of the words “processes” and “equipment”. The main focus is on imaging solutions for non destructive testing of concrete structures, metal hardness testing, paper roll hardness testing and
Issues such as corroded steel, water penetration, and air voids are often embedded within concrete or other solid members. Here, non-destructive testing (NDT) methods must be used to avoid compromising the integrity of the structure. 3D ECT has been used in this field for the non-destructive testing of external tendons on post-tensioned bridges ...
