CEMENT-MORTAR LININGS FOR DUCTILE IRON PIPE

Standards From 1922 to 1929, many installations were made under various manufacturers' specifications. In 1929, ASA Sectional Committee A21 on Cast Iron Pipe issued a tentative standard for cement-mortar linings. This standard was published by AWWA as a tentative standard in 1932. After various revisions and refinements, it was

Flow table test - Wikipedia

The flow table test or flow test is a method to determine consistency of fresh concrete. Flow table test is also used to identify transportable moisture limit of solid bulk cargoes. It is used primarily for assessing concrete that is too fluid (workable) to be measured using the slump test, because the concrete will not retain its shape when the cone is removed.
