Structure and Composition of Aggregates in Two

Thus, the composition and structure of aggregates, chemical gradients, and the assemblage of microorganisms create distinct microhabitats inside aggregates. The ecological relevance of our approach is to reveal environmental heterogeneity on a finer scale.

What Is Aggregate? Properties of Aggregates

2020-7-23  Chemical Properties Of Aggregates. There are three important chemical properties of aggregates: Soundness. This has been looked into and therefore, recycled concrete aggregate is a recent concept. A chemical and mineralogical composition like porosity, strength, hardness, and thermal properties all depend upon the parent rock itself.

Chemical composition of Mineral Trioxide Aggregates

Background and Aim: In 1993, Mineral Trioxide Aggregates (MTA), a grey-colored material was introduced to dentistry. A similar product in white-color was also produced later. The aim of this study was to review the literature in order to compare the chemical composition of these two different types of MTA. Materials and Methods: Over 600 articles have been published about the properties of MTA,...
