“…* corresponding author; e-mail: nbozkurt@beu.edu.tr Sarıyer et al [3] investigated neutron shielding properties of concrete and suggested the usability of ferro-boron in concrete in a form of particle alloy. Özavcı and Çe-tin [4] emphasized that with the growing population, the amount of waste also increases. For this reason, they worked on the evaluation of waste recycling.…”

This paper reports an experimental study on the design of self-compacting lightweight concrete using acidic pumice with different powder materials. For this aim, nine self-compacting lightweight concretes were designed with inclusion of two different fine aggregates and different powder materials. This way, two groups of concrete were designed. First group was composed of single type of aggregate which is acidic pumice from Bitlis Region with barite powder, fly ash powder and pumice powder inclusion, while the second group was generated with river sand as a fine aggregate and acidic pumice from Bitlis Region, as a coarse aggregate with the same powder addition. In the design process, slump-flow, V-funnel and L-box tests were applied to determine the fresh properties of selfcompacting lightweight concrete. After the design, test of compressive strength, which is one of the most important parameters of concrete, was applied to all self-compacting lightweight concretes in early age. Moreover, ultrasound pulse velocity test was also performed on all concrete series at the same ages.

Adsorption is a method of treatment, although adapted to remove a variety of toxic compounds in our environment [9,10]. Several studies in this field are mentioned, the clay minerals have already been extensively investigated to remove various organic pollutants and metal ions, and how to improve their adsorption capacity is critical to practical application.…”

This paper includes the modification of the attapulgite by precipitation of iron and aluminum compounds . Attapulgite (Atta) and modified attapulgite (Atta-m) clays are characterized by many techniques ( FTIR , XRD ,SEM with EDX ) .The attapulgite clay before and after modification were used as the adsorbents for adsorption of methyl green (MG) . The results Indicate ,that the percentage of removal (MG) at equilibrium by using (Atta) and (Atta-m) clay were reached to 94% and 97% respectively. Indicating that the clay modification process was in addition to a relative improvement in the adsorption potential of the clay after modification.

The aim of this study is to investigate the gamma ray radiation absorption properties of bismuth oxide (Bi2O3), and determine the effect of lead oxide (PbO) additive in the shielding of Bi2O3. For this reason, the radiation absorption parameters such as mass attenuation coefficient (MAC), linear attenuation coefficient (LAC), half value layer (HVL), tenth value layer (TVL) and mean free path (mfp) were calculated theoretically for the Bi2O3, PbO, and 50% Bi2O3-50%PbO. The all parameters results were obtained by using the GATE/Geant4 (Geant4 Application for Tomographic Emission) simulation code in energy range 511 keV, 662 keV, 1173 keV, 1274 keV, and 1332 keV. Also, the gamma ray protection parameters were calculated by using the XCOM program in the energy range from 1 keV to 1 GeV. Thus, the simulated the GATE/Geant4 results were tested for correctness using the XCOM program. On the other hand, theoretically were calculated values of all parameters of the shielding materials were compared with each other. These results indicate that the GATE/Geant4 results were in good agreement with the XCOM results.
