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.
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.

Home Fire Safety – Home Elevator Design, Fire Safety Guidelines A home elevator shaft, or hoistway shall be framed with lightweight, or cold-formed, steel – not wood, where exterior surfaces are available for wallboard application, exterior walls. It shall be finished with not less than 1 layer-5/8” Type-X gypsum wallboard glued, screwed and taped and shall be mudded not less than 3 coats, paying particular attention to screw pocks which shall be taped, too.
The clay which the gypsum attracts comes from many sources. The main source is soil erosion. This can occur in rain runoff, from bare croplands, and from over-grazed pastures. A crop cover on the surface of the soil helps prevent this erosion. Livestock on a shoreline or wading in a pond can also suspend sediment, as well as add manure. Ducks, geese, and bottom-feeding fish can affect turbidity. Unusual weather conditions sometimes also stir up sediment. Shallow water allows windy conditions to keep the sediment stirred up.
Pulverised fuel ash can be reduced to a fine powder far more easily than silicate granulate, and its binding activity level is notably higher. When using normal Portland cement and fuel ash crushed to a fineness of 900 m2/kg, the ratio required of Ash to Cement is 1.5. If both of these components are are ground for a similar period (ten minutes) then their specific surface area will be exactly equal to – cement 550, and ash 1312 m2/kg. When using this level of grinding, the required proportion of the components drops to 1:1.
