Tensile Tests of Cement and an Appliance for More Accurate Determinations

Abstract

For the purpose of ascertaining tensile strength, Lipowitz of Germany, in his work on Portland Cement, advises the use of briquettes having a form and size of breaking section 3 × 6 centimetres. I understand that the area of rupture used by French Engineers is commonly 4 × 4 centimetres, though an area of 3 × 4 centimetres is sometimes employed. In England the usual inches. This size is extensively used by Engineers in this country. Sometimes the form is changed, keeping the area the same.
