Polyurethane (PU) is one of the largest polymer products in the plastic family. Structural and
non-structural applications of PU and its variants have become a common and effective …

Asphalt pavement often suffers from rutting, aging, cracks, and pits during the life cycle.
Although traditional polymer modifiers can improve asphalt properties to some extent, its …

This paper presents a mesoscopic discrete modeling approach for studying compression
and fracture behavior of concrete. A modified piecewise linear sieve curve was proposed to …

In this paper, a method for concrete three-dimensional random polyhedral aggregate
mesostructure is proposed. Moreover, a concrete discrete element fracture mesoscopic …

The sustainable performance of asphalt pavement depends on the quality and mix design of
road aggregates. Identifying aggregate morphology and size is a prerequisite step for …

In many exposure environments, capillary absorption of water controls the rate of
deterioration of concrete. This paper presents a three-dimensional numerical investigation of …

Uniaxial tensile behavior of concrete plays an important role in the behavior of concrete
specimens as well as structural elements. A 2D mesoscale analysis is performed to …

A complete understanding of the geometrical structure of concrete is important. Based on the
geometrical characteristics of concrete, hypothesizing that graded aggregates have a fractal …

Over the past few decades, research has been conducted to develop high-strength concrete
(HSC) for high-rise structures and bridge decks. The research discussed in the study …

The characteristic of coarse aggregate is an important factor affecting the building
performance of concrete, so it is of great significance to measure and characterize it. In this …
