Uniaxial compression strength (UCS) is a fundamental parameter to carry out geotechnical engineering design and construction. It is simple and efficient to predict UCS using point load strength (PLS) at engineering sites. However, the high dispersion of rock strength limits the accuracy of traditional fitting prediction methods. In order to improve …
A Feature Paper should be a substantial original Article that involves several techniques or approaches, provides an outlook for future research directions and describes possible research applications. ... Making limestone calcined clay cement (LC 3) is a practical choice because clays and limestone are abundantly available all over the world ...
The "absorption" technique used by limestone to filter water makes it a very effective filtering medium. Limestone filtering needs UV light during water disinfection. Thus it is crucial to keep this in mind while dealing with germs and bacteria. The same permeability of limestone enables bacteria, viruses, germs, and protozoa to enter the ...
It is based on limestone, one of the most common materials on the planet." "Biodolomer does not result in any microplastics and reduces CO2 emissions by up to 80 % compared to fossil plastics if burned." Biodolomer is used for a variety of film-based applications, such as grocery bags, aprons, and various farming uses.
3.1 Surface Area. The surface area, pore diameter size and total pore volume of the limestone media was determined using Quantachrome Instruments. The result from BET analysis shows that, the surface area of raw limestone was 11.12 m 2 /g. However, this media exhibited much lower specific surface area than the common …
