Attenuation Gamma Rays Properties of Cement Paste-Waste Paper Composites

In this study, cement composites were produced with CEN reference sand, cement, water, and waste paper. Waste paper were used as partial replacement 0-0.50 ratios of sand weight which was tagged as CK and WPCK, and the cement-to-sand ratio was kept constant at 1:3. Mix design was based on the standard of TS EN 196-1. The infrared spectra were recorded by accumulating 64 scans each in 4000-400 cm(-1) range with a resolution of 4 cm(-1) with KBr pellets at room temperature. The linear attenuation coefficients of composites were measured using the gamma spectrometer system containing NaI(Tl) detector. The measurements were performed at 1173 and 1332 keV, which was obtained from Co-60 radioactive sources.
