Stabilization of Subgrade Soil for Highway by Recycled Polyester Fiber
Subgrade soil stabilization is one of the primary and major processes in the construction of any highway; also environmental authorities are concerned about the growing amount of polyethylene (PET) bottles produced by household sectors. This research in order to study effect of adding recycled polyester fiber on soil engineering properties, especially shear strength and California Bearing Ratio...

متن کاملThermal stability and structural changes of double-walled carbon nanotubes by heat treatment
We describe, for the first time, the sequential structural changes of bundles of double-walled carbon nanotubes (DWNTs) as a function of heat treatment temperature. DWNTs (inner diameters >0.9 nm) are structurally stable up to 2000 C. Above 2100 C, the outer walls of adjacent DWNTs start coalescing into large diameter tubes. At temperatures higher than 2100 C, three different types of structure...
متن کاملEffect of Heat Treatment on Structural and Magnetic Properties of Nanocrystalline SrFe12O19 Hexaferrite synthesized by Co-Precipitation Method
Nanocrystalline strontium hexaferrite (SrFe12O19) powders have been successfully synthesized using the facile Co-precipitation method. The ferrite precursors were achieved from mixtures of strontium and ferric chloride in an aqueous medium without any surfactant and soft template. The as-received powders were calcined at 800 and 1000 ˚C for 2 hours in air. The final powders were characterized b...
متن کاملStructural adjustments induced by heat treatment in ilvaite
Ilvaite is a mixed-valence Fe-bearing sorosilicate, typically occurring as a late forming mineral in Ca-Fe-Si skarn deposits (Burt 1971). Its chemical composition does not differ significantly from the ideal end-member, Ca Fe2Fe (Si2O7)O(OH), except for a considerable amount of Mn, mainly substituting for Fe and, to a lesser extent, Ca (Carrozzini 1994); minor replacement of Fe and Fe by Mg and...
