Abstract :
[en] Modeling studies of the effect of cement type, aggregate type and w/c ratio on the bound water amount and shielding properties against neutron ionising radiation of concretes are presented. The change of cement or aggregate type had an significant influence on the bound water amount and neutron linear attenuation coefficient (NLAC) calculated in Monte Carlo N-Particle Transport Code. The multiple regression analysis for the dependent variable NLAC suggested no correlation between w/c ratio and examined parameter.. Data gained in ionic chamber implies an influence of cement type on the concrete shielding properties.
