Beryllium | Definition of Beryllium by Merriam-Webster

Beryllium definition is - a chemical element of the alkaline earth metal group with atomic number 4 that occurs naturally in minerals such as beryl and is steel-gray in color, light and strong but brittle, and is used chiefly as a hardening agent in alloys.

Calcium oxide - Wikipedia

Calcium oxide that survives processing without reacting in building products such as cement is called free lime. Quicklime is relatively inexpensive. Both it and a chemical derivative (calcium hydroxide, of which quicklime is the base anhydride) are important commodity chemicals.

Cements made with sodium silicates are used for lining and laying refractory units,preparing foundry molds and cores, laying brick in sulfite digesters for chemical wood pulps,and construction of acid-proof masonry.

Fly ash - Wikipedia

Fly ash often replaces up to 30% by mass of Portland cement, but can be used in higher dosages in certain applications. In some cases, fly ash can add to the concrete's final strength and increase its chemical resistance and durability. Fly ash can significantly improve the workability of concrete.

Beryllium - Be - Water Treatment and Purification - Lenntech

Beryllium as a chemical element occurs naturally in soils in small amounts, but human activities have also increased these beryllium levels. Beryllium is not likely to move deeper into the soil and dissolve within groundwater. In water, chemicals will react with beryllium, causing it to become insoluble. This is a good thing, because the water ...
