GHOST S1 fits a spec that meets the requirements of a hardcore gamer in terms of cooling, storage and full-length GPUs. However, it could be configured in different sizes by adding a TopHat of your choice, making space for extra 3.5″ HDDs, tons of 2.5″ SSDs, additional case fans, 120 and 240 mm AIOs, or just have it as a neat glove compartment

The ASTM Spec. C150 [1] provides for eight types of Portland cement: Types I, IA, II, IIA, III, IIIA, IV, and V, where the "A" denotes an air-entraining cement. These cements are designed to meet the varying needs of the construction industry. Cements used in wells are subjected to conditions not encountered in construction, such as wide ...

Ground calcium carbonate used in the manufacturing of roofing, flooring, and other building materials. Ground calcium carbonate is often used to increase durability and reduce costs by displacing or "extending" other raw materials that are more expensive. It is the ideal raw material as it has low absorption qualities, consistent particle size distribution and color.

the major raw material component. India is endowed with large deposits of limestone. The estimated total re-serves of limestone are 95.623 billion tones. However, ... turers specifications, limestone for cement making, should contain more than 45% CaO; Fe2O3 as well as Al2O3 1% to 2%; free silica less than 8%; combined

limestone than through sand, is troublesome because it renders the batch less fusible. If the sand is derived from indurated sandstone the latter should be friable or easily crushed. In examining sand, in order to ascertain its value for glass-making purposes, inspection with a magnifying glass is the best preliminary test.
