Presently about 200 million tons of urea fertilizer is produced worldwide to meet supply and demand However a quarter of the urea applied to soils is lost to the environment due to poor efficiency
This team led by Hamid Assilzadeh with the critical involvement of Yi Cao Mohamed Amine Khadimallah and Mohd Ahmed has produced a seminal study titled "Enhancing Structural Analysis and Electromagnetic Shielding in Carbon Foam Composites with Applications in Concrete Integrating XGBoost Machine Learning Carbon Nanotubes and Montmorillonite "
Enhancing structural analysis and electromagnetic shielding in carbon foam composites with applications in concrete integrating XGBoost machine learning carbon nanotubes and montmorillonite By integrating Carbon Nanotubes CNTs and Montmorillonite It is typically used to fill bridge bearings in soft soil areas backfill foundation
In the beginning of the 20 th century there was usage of hydrated lime as an admixture in poured concrete Mira et al 2002 Lime was used as the basis for the pozzolanic material in concrete
Following the American Concrete Institute guidelines foamed concrete prepared with IBA as a fine aggregate can be used as medium strength concrete resulting in improved performance and sustainable construction Oren et al [48]
Glass fibers in concrete can be used for more modern and aesthetically pleasing lower weight structures like furniture or architectural claddings on buildings Synthetic fiber in concrete is made up of one of two types of fibers microfibers or macrofibers The use of microfibers in concrete reduces shrinkage cracks and are commonly made of
Finally co calcination of kaolinite and montmorillonite with alkali and alkali earth metal hydroxides NaOH KOH and Mg OH Much research does confirm this and suggests that many reclaimed ashes can be used in concrete without major concerns [55] [108] [109] Reclaimed fly ashes may not help with certain durability measures such as
The researchers at MIT are working on scaling up their carbon cement supercapactor so it can be used in a number of different applications Credit Getty Images
Due to the widespread use of concrete in the world the demand for aggregates is increasing As a result sand with high quality is increasingly difficult to mine Besides the high quality with different contents of montmorillonite was used C1 C2 C3 and C4 represent respectively the aggregate in which 0 3% 8% and 16% montmorillonite are
A total of 12 billion tons of concrete materials are produced annually about 2 tons per person More sustainable buildings are thus needed to decrease the carbon footprint of concrete infrastructures in the context of climate change Crack formation is a major flaw of concrete structures Although cracks are usually small and do not necessarily induce building
The water molecules that occur between the layers in smectites are called low temperature water which can be driven off by heating from 100 to 150°C Grim 1968 It has been shown that the water on the surface between the montmorillonite layers is in a physical state different from liquid water Low 1961 A multitude of studies of this water between the layers
As mentioned in earlier sections improvement in enhancing performance and durability of concrete can be achieved by using nano materials In this sub sections discussion on the nano materials reported by previous researchers and its use in UHPC will be further elaborated Nanoclay is made of montmorillonite mineral deposits known to have
The use of lightweight aggregate is one of the best ways to output light weight concrete research on the use of manufactured lightweight aggregate is still few in the production of lightweight cement free concrete Abdulkareem et al [1] used fly ash class C as pozzolanic material and natural sand and expanded clay as
It is reported indeed that Bauxsol TM a sea water neutralised bauxite residue can replace natural sand up to 10 wt % by cement mass improving concrete durability properties viz carbonation chloride ingress sulphate attack and salt scaling without detrimentally affecting the strength alkali aggregate reactivity modulus of elasticity
Trümer and Ludwig put forward the thesis that one of the obstacles to the wider use of calcined clays in cement and concrete technology is the lack of information on the long time behaviour of the concrete They used clays of various mineralogical composition which they subjected to the process of thermal activation and used in concrete
Montmorillonite can be easily added to your daily ration of food in small quantities This is an excellent idea as it will replicate the Koi feeding continuously off minute mineral rich particles on the floor of mud dams Use calcium bentonite for Koi food Montmorillonite is used directly in the pond water each week in a recommended dosage
Montmorillonite with chemical formula Na Ca Al Mg 2 Si 4 O 10 OH 2n H 2 O is a very soft phyllosilicate group of minerals was first described in 1847 for an occurrence in Montmorillon in the department of Vienne France more than 50 years before the discovery of bentonite in the US [1] Its structure is well known nearly 7 decades [2] Several classification
Due to the widespread use of concrete in the world the demand for aggregates is increasing As a result sand with high quality is increasingly difficult to mine Besides the high quality with different contents of montmorillonite was used C1 C2 C3 and C4 represent respectively the aggregate in which 0 3% 8% and 16% montmorillonite are
The composite exhibited a good thermal and chemical reliability when subjected to 3000 thermal cycles Besides the prepared composite can be successfully utilized into mortar and concrete Montmorillonite as supporting material for PCM Bentonite or montmorillonite group is a natural industrial mineral [83]
Geological disposal is the preferred option for the final storage of high level nuclear waste and spent nuclear fuel in most countries The selected host rock may be different in individual national programs for radioactive waste management and the engineered barrier systems that protect and isolate the waste may also differ but almost all programs are
Metakaolin MK is known to be a highly pozzolanic material that can be used in concrete MK is usually produced by heating kaolin containing clays within the temperature range of about 600 900 ℃ 2 1 layered clays such as illite and montmorillonite can be used but tend to show lower pozzolanic activity
The use of montmorillonite has been investigated as a delivery system for active substances and few studies report discussions and visualization of publications on this topic Thus the objective of this study is to explore related research fields from a bibliometric perspective characterize current trends and present visual representations of the last
The properties of self compacting concrete SCC can be manipulated by the addition of nano montmorillonite NMMT clays This paper presents the results of an experimental investigation on
