“…The simulations were performed for a specific concrete mix design [39,40]. The specimen size simulated to obtain the microstructure of cement is 100 μm × 100 μm × 100 μm, with the mix as follows: Portland cement with a maximum cement size of 50 μm, a w / c ratio of 0.567, air content 0.6%, and a curing temperature of 20 °C.…”

“…The upscaling of the remaining ten parameters requires further study related to the compression microscale model and, therefore, is not presented in this paper. The experimental data needed as input have been collected from [ 39 , 40 ] and include the following information: At the cement paste (microscopic) scale, the chemical composition was obtained from inductively coupled plasma mass spectrometry (ICP); and the mineralogical composition of the cement was obtained using X-ray analysis (XRD). At the macroscopic level, a uniaxial compression test (at the age of 169 days) was performed on a concrete specimen to calibrate and validate the numerical models at the concrete meso scale.…”

“…In this study, the HYMOSTRUC3 model [ 28 ], which has been validated through experiments (e.g., [ 43 ]), is used to simulate the cement hydration and microstructure of the cement paste. The simulations were performed for a specific concrete mix design [ 39 , 40 ]. The specimen size simulated to obtain the microstructure of cement is 100 μm × 100 μm × 100 μm, with the mix as follows: Portland cement with a maximum cement size of 50 μm, a w / c ratio of 0.567, air content 0.6%, and a curing temperature of 20 °C.…”

Modeling the complex behavior of concrete for a specific mixture is a challenging task, as it requires bridging the cement scale and the concrete scale. We describe a multiscale analysis procedure for the modeling of concrete structures, in which material properties at the macro scale are evaluated based on lower scales. Concrete may be viewed over a range of scale sizes, from the atomic scale (10−10 m), which is characterized by the behavior of crystalline particles of hydrated Portland cement, to the macroscopic scale (10 m). The proposed multiscale framework is based on several models, including chemical analysis at the cement paste scale, a mechanical lattice model at the cement and mortar scales, geometrical aggregate distribution models at the mortar scale, and the Lattice Discrete Particle Model (LDPM) at the concrete scale. The analysis procedure starts from a known chemical and mechanical set of parameters of the cement paste, which are then used to evaluate the mechanical properties of the LDPM concrete parameters for the fracture, shear, and elastic responses of the concrete. Although a macroscopic validation study of this procedure is presented, future research should include a comparison to additional experiments in each scale.

“…In order to validate our methodology, we performed uniaxial compression tests on three types of concrete specimens with a cross section of 100 mm Â 100 mm [see also [28,29]]: two sets of specimens of 100 mm height with LF and HF boundary conditions and one set of specimens of 200 mm height with LF boundary conditions. These experimental results were then compared to LDPM simulations using the following parameters:…”

We propose an upscaled methodology for evaluating the compressive parameters of the Lattice Discrete Particle Model (LDPM) for a multiscale analysis of concrete structures. This methodology is based on mechanical and chemical models on a wide range of concrete scales. We show that the compressive mechanical parameters are related mainly to material compaction that occurs at the scale of cement paste, the scale containing porosity properties. Therefore, these compressive LDPM parameters are subsequently evaluated based on chemical and mechanical simulations at the cement paste level. Finally, the suggested methodology was verified and validated.
