Gamma radiation determination of absorption coefficients of cement sand block
Abstract
Three bands of cement with different trade names, Dangote, UNICEM, and Eagle cement were separately molded into cement-sand blocks at different proportions of cement sand ratio of 2:3, 3:7 and 1:4 by weight for each of the cement brand were prepared and allowed to cure. We exposed the blocks to gamma radiation for the determination of attenuation coefficient, half thickness, and mass absorption coefficient. We also determined density values for the blocks. The results for the cement samples show that the higher the cement content in the cement sand block, the higher the density value and the gamma attenuation coefficient, suggesting that cement sand block with a high proportion of cement content makes for a good shielding in gamma radiation exposed environment, Gamma radiation attenuation the method can equally be a useful technique for cement sand block quality control in building construction industry.
