essential goods which were threatened by the war. Glanville's first investigation at the Building Research Station (BRS) was to study how the water permeability of concrete varied and, with Duff Abrams, was one of the first to attribute this primarily to the water-cement ratio and not to the type and proportions of aggregate used. He also found that concrete became much more impermeable when cured by immersion in water, compared with the more popular air curing method. He continued his work in this field, investigating the bond between concrete and steel reinforcement, shrinkage of the material and creep and flow under load. Glanville's work was among the first scientific research into reinforced concrete, the design and installation of which had previously been governed almost entirely by practical experience rather thean scientific theory. Glanville's became an associate member of the Institution of Civil Engineers in 1925. In 1925 the BRS moved to Garston near Watford. After the move Glanville's focus switched to development of new methods of testing building materials, designing and installing new testing equipment at the BRS and carrying out research on concrete, structural steel, brickwork and the acoustic properties of materials. His work on the creep and flow of concrete led to a PhD from the University of London in 1927. Glanville was appointed head of the BRS' engineering section ("Chief Engineer") in 1928. His responsibilities encompassed all of the BRS's engineering work including the management of its research, development of equipment and investigations of structural failures as well maintenance and expansion of the station. Glanville continued his own research into concrete and received, in 1930, a DSc degree from the University of London. In later life he reflected on this period of his career as his happiest and most professionally rewarding. In 1931 he was consulted by London County Council on the drawing up of a code of practice for the use of reinforced concrete in buildings. The report, drawing heavily on Glanville's research, was published in 1933 and later incorporated into British Standards code 114. His research covered almost every aspect of concrete use in construction and included shrinkage stresses, creeping, and permeability as well as work on indeterminate structures, timber roofs, and curved bracing members. Some of his later work in the field focussed on continuous reinforced concrete beams and portal frame structures and he was the first to show that apparent increased in load-bearing
