This approach considered the variation in properties of type I Portland cement for 0, 5, 10, and 15% volume fractions of two kind of glass microspheres; one was high density with high crushing strength, and the other with a relative lower density. Using a suite of software called Virtual Cement and Concrete Testing Laboratory (VCCTL), the microstructural details were determined for 80% degree of hydration of the cement mixture for these different volume fractions. The VCCTL-generated three dimensional heterogeneous microstructures with various micro-constituents, such as the C-S-H gel, tricalcium silicate, and other cement byproducts, were explicitly modeled in ABAQUS© commercial finite element code. The representative volume element (RVE) in ABAQUS was a 100x100x100 μm3 cube. Since the symmetry as well as the anisotropy of the cementitious material system is not fully established, iso-strain based boundary conditions were applied to this RVE towards determining various elements of the elastic tensor. The computationally calculated elastic moduli compared reasonably well with data from quasi-static compression tests for various volume fractions of the glass microspheres.","abstract_html":"The effect of volumetric replacement of cementitious materials by an inert filler known as hollow glass microspheres on elastic properties is evaluated in this study through a combined computational and experimental approach.
