The Structural Engineer

THE subject of creep occupies an important, place in the literature on concrete of recent years. Creep is the non-elastic deformation which, under sustained load, will increase for several years with a magnitude of several times the initial elastic strain on loading. The major part of this deformation is due to colloidal seepage and so is not really a true creep in the accepted sense. In unstressed concrete, shrinkage is largely due to the same cause, but under stress the seepage is accelerated; colloidal water is forced out of the gel under pressure into the capillary channels and thence to the surface where it is evaporated and an increased deformation is the result.

The PRESIDENT(Lt.-Colonel C.H. Fox, O.B.E., B.Sc., F.S.I,) commented that Dr. Glanville had gained a great reputation by reason of his work, and the members of the Institution were glad to have a second opportunity to hear him discuss the subject of strength tests for cement.

THE CHAIRMAN (Sir George Humphreys, K.B.E., M.Inst.C.E., President of the British Section of the Societe des Ingenieurs Civils de France), opening the proceedings, drew attention to the fact that the occasion was the 71st ordinary general meeting of the British Section of the Societe des Ingenieurs Civils de France held jointly with the Institution of Civil Engineers and the Institution of Structural Engineers. To all the members of the two latter Institutions he extended, on behalf of the members of the British Section of the French Societe, a cordial welcome; and he tendered to the Council of the Institution of Civil Engineers the grateful and appreciative thanks of all present for its hospitality and kindness in placing the lecture theatre at their disposal.

THOUGH Soil Mechanics is not by any means a new science it is only of recent years that a serious attempt has been made to study the foundation soil by practical as well as by theoretical means. The recent progress has been truly phenomenal. F.L.D. Wooltorton
