(1) the volume of freshly mixed concrete produced from a known quantity of ingredients; (2) the total mass of ingredients divided by the densitymass of the freshly mixed concrete; (3) the number of units produced per bag of cement or per batch of concre
the first engineering stress in a test in which stresses and strains are determined for a material that exhibits the phenomenon of discontinuous yielding, of which an increase in strain occurs without an increase in stress.
the stress at which a material exhibits a specific limiting deviation fromthe proportionality of stress to strain.
(1) a tie or clamping device around column forms or over the top ofwall or footing forms to keep them from spreading because of the lateral pressure of fresh concrete; (2) part of a structural assembly for slipforming that keeps the forms from spreading
