An example of this is in the case of NaCl (table salt), where the ionic bonds between sodium and chloride ions join to make isometric crystal lattice structures at the microscopic level, collectively making the mineral to the human eye appear isometric in shape (cube shaped). Therefore, the...
Mineral Class: Quartz Locality: Found mainly in Burma, Sri Lanka, South Africa, China, USA, Tanzania, Madagascar, India and Australia Garnets are a group of silicate minerals that have been used since the Bronze Age as gemstones and abrasives. All species of garnets possess similar physical ...
General table of mineral basic structure types 来自 Springer 喜欢 0 阅读量: 14 作者: J Lima-De-Faria 摘要: Now that we have produced the three volumes of the structural classification of minerals, we might care to provide a bird's-eye view of the main mineral structure types. To do ...
Charoite, apurple to violet silicate mineral, is known for its striking appearance and vibrant colors. When you first lay eyes on it, you’ll be captivated by its unique range of purple shades, which can vary even within a single specimen. This mineral is beautiful and displays interesting ...

Generally, alkali–silica reaction (ASR) is considered as an internal chemical reaction between the alkaline components in the cement and active silica–silicate based mineral constituents of some aggregates. The use of aggregates susceptible of ASR in concrete can cause a severe degradation of the...
Therefore, the main aim of this research is to evaluate the influence of cement mortar type on fresh mortar (slump flow test), and hardened mortar (apparent density, compressive strength and modulus of rupture) by using mineral admixtures (silica fume), as a partial replacement (8%) by ...
