study of water permeability in concrete by neutron and gamma-ray techniques

Water infiltration in various building materials, namely concrete used for buildings basement and underwater construction is the main concern of the studies performed in this thesis. The studies aim to develop concrete mixes with different additives capabWater infiltration in concrete samples with different percentages of silica fume and submerged in tap and seawater for different periods of time was studied by neutrons and gamma techniques. Also, water propagation in mortar samples made of sand, cement a
