There are five different types of cement in the dental field each is versatile in their properties, uses, and mixing techniques. Many were traditionally used for routine cementation through the nineteen ninety’s and since have been replaced by newer makeup and mixing techniques. The selection of cement for a specific procedure requires knowledge of the…

PORTLAND CEMENTChemical composition. Portland Cement is made up of four main compounds: tricalcium silicate (3CaOSiO2), dicalcium silicate (2CaOSiO2), tricalcium aluminate (3CaOAl2O3), and a tetra-calcium aluminoferrite (4CaO Al2O3Fe2O3). In an abbreviated notation differing from the normal atomic symbols, these compounds are designated as C3S, C2S, C3A, and C4AF, where C stands for calcium oxide (lime), S…

Analysis The purpose of Part 1 of this laboratory is to construct a table listing the reduction potentials of a series of metal ions in order of ease of reduction. The series of half-cells is constructed by placing a piece of metal into a 1.0 M solution of its ions for each metal in the…

1.0 INTRODUCTION This report is a practical experience acquired by me in the course of my industrial training at Druckfarben Nigeria Limited (DFN) under the student industrial work experience scheme (SWIES). In the earlier stage of science and technology education in Nigeria, students were from their respective institutions without any technical knowledge or working experience….

One important quality of water that supports life on Earth is its unique ability to have floating ice. This occurs because when water freezes, hydrogen bonds form between water molecules, creating a crystalline structure. This structure allows each molecule to bond with four neighboring water molecules. Compared to liquid water, solid water has bonds that…

Acid rain is perhaps the most well-known and recognizable form of pollution that is affecting the world today. Acidity is measured using a pH scale with 7 being neutral. So anything below 7 is considered to be acidic. but as far as acid rain goes. the baseline for identifying acid rain is generally below the…
