Concrete is a composite material with a variety of inhomogeneities. Its composite behavior may be studied analytically using the mesoscopic approach which treats the concrete as a three-phase system consisting of coarse aggregate, mortar matrix with fine aggregate dissolved in it, and interfacial zones between the coarse aggregate and the mortar matrix. For such mesoscopic study, it is first necessary...
At mesoscopic scale, concrete may be regarded as a three-phase composite consisting of coarse aggregate, mortar matrix and interfacial zones. Its composite behavior can be studied by generating a random aggregate structure which resembles the mesoscopic structure of concrete and analyzing the interaction between the three phases using the finite element method. A method of generating random aggregate...
