Abstract
A high performance engineered composite cementitious ductile mortar including a predetermined amount of matrix interactive fibers; a water reducer having a plasticizing effect; and a defoamer/plasticizer having a plasticizing effect. A carboxylic acid polymer or carboxylic acid copolymer based superplasticizer are not included in the defoamer/plasticizer or the water reducer.
