Abstract:Expansive cement motar can be used in construction with Type 1 cement motar to develop a composite beam, which after curing will have residual compressive stresses on the tensile surface which can result in significantly increased flexural strength. The magnitude of the increased flexural strength, for a particular beam geometry and a particular expansive cement, depends on the relative thickness of the layers of the two mortars.
