Study of water movement in concrete

摘要: An investigation on the movement of water in 100% Portland cement concretes is presented. The diffusion and sorptivity tests, together with accelerated permeability test, are performed to determine transport parameters that characterise mechanisms diffusion, concrete respectively. effects pore humidity, ambient temperature, environmental relative applied hydrostatic pressure gradient water-cement ratio also explored. results obtained from tests show good agreement those reported literature. study has practical implications prediction distribution aggressive chemical agents concrete, as well development rational quantitative durability assessment for structures exposed different climatic conditions.
