Abstract

Neutron diffraction studies of the static structure factor S(Q) of water confined in the pore space of cement samples have been carried out for temperatures from 170 to 293 K. At high temperatures, when the water in the pores is liquid, a fraction of the water molecules are strongly bound to specific adsorption sites on the crystalline components of the cement. On cooling, the water in the pore space solidifies at 245 K into a cubic structure different from that of bulk water at similar temperatures.
