### Mesoscale Modeling Of Cement Matrix Using The Concept

Calcium silicate hydrate (csh) gel is the cohesive phase in cement paste and critically controls the cement hydration. atomistic models can reproduce reasonable structural and mechanical properties of csh gel at the nano scale. however, the length and time scale of such allatom modeling technique are restrained by limited computing power. under this.

### Mesoscale Modeling Of Chloride Penetration In

In the mesoscale model, concrete is treated as a threephase composite material consisting of coarse aggregates, mortar matrix, and interfacial transition zone (itz) between the aggregate and the mortar matrix. the diffusivities of each phase, (i.e., water and chloride diffusion coefficients) is separately characterized and quantified in terms.

### Mesoscale Modeling Of Concrete: Geometry And Numerics

Mesoscale analysis is a promising discipline for concrete mix design and damage prediction. besides many other aspects, its success crucially depends on accurate modeling of the mesoscale geometry and efficient numerical analysis of high resolution, to both of which this article contributes.

### Mesoscale Modeling Of Cement Matrix Using The

Mesoscale modeling of cement matrix using the concept of building block volume 1759. here, we regard the building block of cement as ellipsoid and develop a coarsegrained model of cement matrix based on the gayberne (gb) potential. emphasis of the present paper is on the parameterization and interpretation of the gb potential formula.

### Mesoscale Modeling Of Concrete Timedependent Behavior

Mesoscale modeling of concrete timedependent behavior. creep and shrinkage of concrete are timedependent deformations that influence primarily the serviceability, and in some cases also the safety, of reinforced concrete structures with and without prestressing. shrinkage is mainly driven by both selfdesiccation and moisture drying if.
