Study of Chemical and Mineralogical Composition of Sylvinites of Tubegatan Mine
No full textThe study delves into the chemical and mineralogical composition of sylvinites extracted from the Tubegatan mine. Through x-ray analysis of various components, including sylvinite samples and insoluble residues obtained during experimental melting processes, the research investigates the intricate composition of these materials. By scrutinizing the results of the x-ray analysis, the study unveils crucial insights into the chemical makeup and mineralogical properties of the sylvinites. Furthermore, the research scrutinizes the process of melting different samples of sylvinite to elucidate potential variations in composition and behavior under thermal conditions. This comprehensive analysis provides valuable knowledge essential for understanding the characteristics and properties of sylvinites from the Tubegatan mine, contributing to advancements in the field of mineralogy and facilitating informed decision-making in mining and processing operations
INGREDIENT OF PORTLAND CEMENT
No full textPortland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout. It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and is usually made from limestone. It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker, grinding the clinker, and adding 2 to 3 percent of gypsum. Several types of portland cement are available. The most common, called ordinary portland cement (OPC), is grey, but white Portland cement is also available. Its name is derived from its resemblance to Portland stone which was quarried on the Isle of Portland in Dorset, England. It was named by Joseph Aspdin who obtained a patent for it in 1824. However, his son William Aspdin is regarded as the inventor of "modern" portland cement due to his developments in the 1840s
