Effect of Gamma Irradiation on Pore-Space of Hardened Cement Paste
Popis výsledku v původním jazyce
Hardened cement paste (HCP) has been exposed to ?-irradiation up to a dose of 1 MGy and then the changes of properties of the porous space were studied by mercury porosimetry and adsorption of nitrogen. This properties were pore size distribution of pores and mesopores, specific volume and specific area of pores and micropores, mean (average) pore and micropore diameter, median pore diameter, porosity, body density and skeleton density. The samples were prepared as a blend of Portland cement and water with w/c ratio of 0.4. The mixture was cast into moulds of size 0.08 x 0.16 x 0.01 m and demoulded 24 hours later. After six month of curing and ageing all samples were relocated to the irradiation chambre and exposed to ?-irradiation up to a dose of 1 MGy. Changes in porous space are in this paper interpreted by two independent phenomena: the shrinkage due to radiation drying and the radiation carbonation.
