Improves water-use efficiency: Gypsum application increases water-use efficiency of crops. Improved water infiltration rates, improved hydraulic conductivity of soil, better water storage in the soil all lead to deeper rooting and better water-use efficiency.
NOTE: Remember to adjust the home elevator system’s manufacturer’s shaft framing dimensions to accommodate thicker interior clad; advise the elevator system manufacturer (and your local Fire Marshal) of your specific intentions in regard to home fire safety methods and materials early-on.

The results of determining the activity-level of finely-ground grit and waste glass by-products show the weak level of binding these additives have with calcium oxide – quite separately from the specific surface areas of these additives and the Portland cement. These means that these additives need to be used in GFP alongside microsilicates. It follows, therefore, that complex silica-based additives has a synergetic effect, and the microsilicates in it can be considered to be the component that guarantees the long-lasting durability of the products made with it. The presence in complex silica-based additives of super-plasticisers or other kinds of surfactants moves them up into the category of organic mineral modifiers. They contribute to an intensified mechanical activation while shortening the duration time of the activation process. The resulting GMM not only gives the gypsum binder hydraulic properties, but also regulates the other binder properties in a desirable direction too. Examples include slowing the setting time, lowering average density, boosting strength under tension or pressure, impact resistance, burst instability, and other factors. Production of GMM could be organised on a centralised basis – for example, at plants which produce dry building material mixes. Thanks to these universal modifiers, the GMM capabilities of composite gypsum binders and available through their application acquire a whole new range of possibilities which are more typically characteristic of Portland cement. However, they continue to have the same primary benefits of gypsum binders – rapid setting and hardening. Alongside this GFP also has low demands on water – thus opening up opportunities for manufacturing which does not involve any heat treatment processes.
Prevents crusting of soil: Gypsum application can decrease and prevent the crust formation on soil surfaces which result from rain drops or from sprinkler irrigation on unstable soil. It can prevent crusting that result when acid soils are limed and the gypsum is coapplied with the lime.
Gypsum’s debut exhibition, ’Spectral Days’, is an unusual photography curation from international artist, Setareh Shahbazi. Born in Tehran in 1978 but forced into exile to Germany in 1985, Shahbazi presents a collection of her own family photographs from around this time, which have been revived and revamped through various experimental digital techniques. Exploring the remembrance of the past, captured in old photographs, there’s a powerful, overarching meaning behind the exhibition.
