penetration. The diffusion of copper varies as an inverse function of carbon composition. Activation energies of carbon diffusion in steel are also found to increase with increasing braze temperatures and the corresponding carbon content [ 2 ]. Yoshida et al

potential of the chitin filler as shown in Table 3 . The weight loss on ignition is a measure of the carbon content lost during combustion and equally an indication of the effectiveness of the material. The higher the value, the greater the reinforcing

that of the specimens of NRS (Natural River Sand) at 28 days of curing [ 21, 22 ]. In another study [ 23 ], two types of FA (Fly ash) were developed with class F (High carbon content) geopolymer fine aggregate (F-GFA) and class C (Low carbon content

element contents were measured with the inductively coupled plasma atomic emission spectroscopy technique after fusion with Li metaborate. The inorganic carbon content was measured volumetrically after HCl treatment. Uncertainties of the measurements were

. Considering chemical formula of PET, it is easy to find out that carbon content in this material is ca. 63% [ 10 ]. However, in spite of this high value, pyrolysis of PET results in significant, ca. 80% or more mass loss, which gives only ca. 20% or less
