Multiscale hydro-thermo-mechanical model for early-age and mature concrete structures

Temperature and early-age mechanical properties in hydrating concrete structures present a significant risk for cracking, having a major impact on concrete durability. In order to tackle these phenomena, a multiscale analysis is formulated. It accounts for a high variety of cement properties, concrete composition, structure geometry and boundary conditions. The analysis consists of two steps. T...

Efficient thermo-mechanical model for solidification processes

A new, computationally efficient algorithm has been implemented to solve for thermal stresses, strains, and displacements in realistic solidification processes which involve highly nonlinear constitutive relations. A general form of the transient heat equation including latent-heat from phase transformations such as solidification and other temperature-dependent properties is solved numerically...

Concrete Block Pavement for Low Volume Roads

Concrete block pavement (CBP) is a durable pavement for carrying light as well as heavy loads, and it is being used widely for construction of city streets, parking places, gas stations, container stacking yards, residential areas and low volume roads. This paper presents the findings of a laboratory investigation on structural behaviour of CBP. Plate load and Accelerated Pavement tests were ca...

Measuring and Analyzing Pavement Texture Concrete Pavement Surface Characteristics Program

Introduction Pavement texture is defined by the irregularities on a pavement surface that deviate from an ideal, perfectly flat surface. As shown in Figure 1, the World Road Association (PIARC) has established standard categories of texture, classified by wavelength. These categories include microtexture (wavelengths up to 0.5 mm), macrotexture (0.5 to 50 mm), megatexture (50 to 500 mm), and ro...

The Influence of Graphene Oxide on Mechanical Properties and Durability Increase of Concrete Pavement

Herein, the performance of graphene oxide (GO) in improving mechanical properties and subsequently reducing the permeability of cement composites used in concrete pavement, is studied. A polycarboxylate superplasticizer was used to improve the dispersion of GO flakes in the cement. The mechanical strength of graphene-cement nanocomposites containing 0.1–2 wt% GO and 0.5 wt% superplasticizer was...
