TL;DR: A comprehensive review of the scientific and technical achievements of microwave-assisted concrete treatment can be found in this article, where the theoretical fundamentals for the microwave assisted concrete heating process are investigated in detail, covering areas such as the microwave heating characteristics, governing equations, dielectric properties and multi-field coupling effects.

TL;DR: In this article, a new model to predict the permanent strain of unbound gravel mixture was proposed based on the performance of single-size gravels and the contribution of coarse and fine aggregate in the gravel mixture.

TL;DR: In this paper, the authors investigated the heating process of aggregate-mortar interfaces under microwave irradiation and provided a contribution and reference for the further application of microwave-assisted aggregates recycling.

TL;DR: In this paper, the effect of compaction energy was considered in frozen stage under closed system, and the results showed that frost-heave ratio first increased with the increase in fine content, and then decreased with the increasing in fines content.

TL;DR: In this paper, the authors investigated the fracture behavior of commonly used coarse aggregates: granite and basalt were investigated by microwave heating tests and found that basalt fracture occurred with more damage at higher power level.
