1.1 This guide focuses on obtaining the comparative moisture condition within the upper 1.0 in. (25.4 mm) stratum in concrete, gypsum, anhydrite floor slabs and screeds for field tests. Due to the wide variation of material mixtures and additives used in floor slabs and screeds, this methodology may not be appropriate for all applications.
It is used to control the setting time of cement but if it is in excess it may unsound the cement concrete because of sulfate Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite .
Make sure this fits by entering your model number.; Perfect and convenient to determine the moisture content of the wood or building materials. Moisture detector measure range of 6% -40% for wood, and 0.0% -8.5% for building materials (cement screed,concrete,plaster,anhydrite, cement mortar, …
Tiling onto Calcium Sulfate (anhydrite) screeds Posted by Philip Jenkins on 15th July 2015 Calcium Sulfate or anhydrite screeds have grown in popularity over the last decade as they offer substantial benefits over traditional sand:cement screeds.

Anhydrite is a mineral—anhydrous calcium sulfate, CaSO 4. It is in the orthorhombic crystal system, with three directions of perfect cleavage parallel to the three planes of symmetry . It is not isomorphous with the orthorhombic barium ( baryte ) and strontium ( celestine ) sulfates, as might be expected from the chemical formulas.
Anhydrite: Anhydrite from Balmat, New York. This specimen of massive anhydrite has a typical gray color and a sugary appearance on broken surfaces caused by exposure of cleavage faces. This specimen of massive anhydrite has a typical gray color and a sugary appearance on broken surfaces caused by exposure of cleavage faces.
In addition, anhydrite is slightly harder and denser compared with gypsum and may have a bluish tint. Both gypsum and anhydrite are used as soil additives and in portland cement. Because of its use in drywall manufacturing, gypsum is more economically desirable. gypsum crystals
Anhydrite cement causes significant heterogeneity within the San Andres reservoir of the Vacuum Field where it is associated with faults, fractures, karst zones and highly cemented dolomite intervals. The primary reservoir rocks within the Central Vacuum Unit of the Vacuum Field are dolomitized peloidal packstones, skeletal and ooid grainstones and fusulinid packstones.

Anhydrite screeds are not compatible with cement based adhesives, which is the majority of them. The chemicals in the screed (the sulphates) can react with those found in cement (the aluminates). This results in the production of a powder (ettringite) which can critically damage the screed itself, as well as weaken the bond to the floor tile ...
Anhydrite cement is common in sedimentary rocks, yet its origin is poorly understood. The high concentration of sulfate in sea water and the lack of appreciable sulfate in most other natural waters suggests that anhydrite cement may have a marine origin, but the relatively late timing of most ...
