Natural factors related to the differential heating of aggregates exposed to microwaves

Novel Processing Methods of Low-Clinker Multi-Component Cementitious Materials—A Review

“…The specimens' microwave heating characteristics can be varied by the secondary material's propensity to absorb, transmit, or reflect MW-T [119]. It has been proven that microwave-assisted heating can cut processing times and lower the expenses of additive manufacturing [104][105][106][107][108]120,121]. Combining these approaches for the best materials processing could be plausible (Figure 10), and it would follow the properties of power ultrasound, microwave, and magnetic processing stated in the preceding chapters.…”

“…Because of its significant benefits of non-contact heating, volumetric and selective heating, user-friendly control, clean heating processes, and no formation of secondary waste, MW-T has recently received much attention [104][105][106][107][108]120,121]. Unfortunately, this may significantly impede the implementation and advancement of such technology in the pavement engineering of the typical cement concrete's low microwave absorption efficiency, which may reduce the microwave heating speed [104][105][106][107][108][109]122].…”

Microwave heating mechanism and self-healing performance of asphalt mixture with basalt and limestone aggregates

“…Asphalt pavement is paved with asphalt mixture composed of asphalt, mineral aggregates and filler [5], the service life of asphalt pavement is closely related to the mechanical strength and shape of aggregates [6]. Aggregates ensure the stable structural strength of the asphalt mixture [7], so there are higher requirements for aggregates in the design of asphalt pavement.…”
