Improvement of Kaolinite Clay Subgrade Using Coir Fiber Waste
Abstract-Since highways are widely used modes, it is necessary that it should be maintained properly. Subgrade being the support for the whole pavement, it needs the utmost care in its construction. Many suggestions have been put forward by various scientists to improve the subgrade. The usually adopted methods are stabilization methods. This paper deals with the improvement of properties of ka...
متن کاملThe Kaolinite Clay Minerals Using Infrared Emission Spectroscopy
Abs t rac t -The dehydroxylation of a series of the kaolinite clay minerals, kaolinite, halloysite and dickite, has been investigated by Fourier transform in situ infrared emission spectroscopy over a temperature range of 100 to 800 ~ at both 50 and 5 ~ intervals. Excellent correspondence was obtained between the high temperature emission spectra and FTIR absorption spectra of the quenched clay...
متن کاملAdhesion of the clay minerals montmorillonite, kaolinite, and attapulgite reduces respiration of Histoplasma capsulatum.
The respiration of three phenotypes of Histoplasma capsulatum, the causal agent of histoplasmosis in humans, was markedly reduced by low concentrations of montmorillonite but was reduced less by even higher concentrations of kaolinite or attapulgite (palygorskite). The reduction in respiration followed a pattern that suggested saturation-type kinetics: an initial sharp reduction that occurred w...
متن کاملHeterogeneous reactions of gaseous HNO3 and NO2 on the clay minerals kaolinite and pyrophyllite.
Airborne clay mineral particles have long atmospheric lifetimes due to their relatively small size. To assess their impact on trace atmospheric gases, we investigated heterogeneous reactions on prototype clay minerals. Diffuse reflectance infrared spectroscopy identified surface-adsorbed products formed from the uptake of gaseous nitric acid and nitrogen dioxide on kaolinite and pyrophyllite. F...
متن کاملAdsorption of Cu ( II ) and Ni ( II ) in Aqueous Solution using Biofilm Supported with Kaolinite Clay
Adsorption of each of the ions Cu (II) and Ni (II) on Escherichia coli ATCC25922 and Staphylococcus epidermidis RP62A supported by kaolinite clay in a batch system was investigated. Equilibrium adsorption capacity was determined to be a function of the solution pH, contact time, and initial metal concentrations. The results obtained from the adsorption experiments were used to understand the dr...
