Applying gypsum helps reclaim sodic soils where sodium that's attached to the cation exchange complex becomes too high. The most economical way is to add gypsum which supplies calcium. The calcium supplied by gypsum displaces the sodium held on the clay-binding sites. The sodium on the clay binding sites can then be leached from the soil with ...
Gypsum is the name given to a mineral categorized as calcium sulfate mineral, and its chemical formula is calcium sulfate dihydrate, CaSO 4 ⋅ 2H 2 O. However, a broader definition includes all the calcium sulfates, including calcium sulfate hemihydrate, CaSO 4 ⋅ 0.5H 2 O, which is known as plaster or plaster of Paris (POP). Figure 6 summarizes the polymorphism of calcium sulfate; …

Keep both hands on grinder! Blade is solid, balanced. Teeth are thick, so wide cut. Good for carving out. Ordering a 2nd one. Update: Broke one of the teeth on a rock. Still cuts well. Using them on a battery powered grinder which shuts off on a snag. Using 2nd on a low amp grinder since when cutting branches there is a hefty kick back.
Portland cement is made by heating limestone and clay to form clinker, then grinding that clinker and adding a mixture of gypsum. When mixed with water and aggregate, it forms concrete. According to Dr. Jackson, Roman concrete was made using the "antithesis" of this process, meaning there is no cement in the material.
Gypsum board, drywall or plasterboard is a building product used in modern construction for efficient, cost effective fire protection that can be easily installed and decorated. The gypsum board production process generally consists of calcining and or grinding gypsum powder, forming a gypsum panel product and drying off any excess water.

Unfortunately has a variety of grinders. The "bare tool" part means he wants a cordless tool without the battery. So probably 20V MAX. But there is still a variety of types of grinders. I add exactly the tools I want to an Amazon list shared with my wife.
Gypsum is the most commonly used amendment for sodic soil reclamation and for reducing the harmful effects of high-sodium irrigation waters because of its solubility, low cost, and availability. Gypsum added to a sodic soil can cause permeability changes by increasing EC and by cation exchange effects.

Gypsum (CaSO 4.2H 2 O) is the hydrated form of Calcium Sulphate (CaSO 4). Calcium Sulphate is a by-product of the evaporation of lake and seawater and occurs in beds up to several metres thick. Calcium Sulphate Dihydrate (Gypsum) is commonly hydrated by groundwater. The UK is largely self-sufficient in gypsum.
Gypsum is a mineral and is hydrated calcium sulfate in chemical form. Gypsum plays a very important role in controlling the rate of hardening of the cement. During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process. Gypsum is added to control the […]
Gypsum is the neutral salt of a strong acid and strong base and does not increase or decrease acidity. Dissolving gypsum in water or soil results in the following reaction: CaSO 4 ·2H 2 O = Ca 2 + + SO 4 2- + 2H 2 O. It adds calcium ions (Ca 2 +) and sulfate ions (SO 4 2-), but does not add or take away hydrogen ions (H+). Therefore, it does ...
Back-blocking is designed to minimize ridging by placing butt joints between framing members. The drywall is hung perpendicular to the framing members, so that the butt ends can be reinforced along the back of each panel, behind the joint. The panel seams can be reinforced by installing a drywall panel behind the seam (see the drawing below).

Gypsum is 20 to 23% calcium by weight, and also contains also 15 to 18% sulfur by weight. This makes it a great choice to supplement calcium if you are also worried about a lack of sulfur in your soil. (On the other hand, Epsom salt is a good choice if your soil lacks magnesium and/or sulfur). As an added bonus, gypsum will leach sodium from soil.
