TL;DR: In this article, the authors detect the healing effect of asphalt mastic and porous asphalt concrete caused by induction heating and conclude that the self healing rate of both mastic beams and asphalt concrete can be increased by induction heat.

TL;DR: In this paper, a surface modification method was proposed to introduce strong polarity groups to rubber surface to generate a strong chemical bond between the rubber and the cement matrix, which greatly improved the interfacial bonding strength between crumb rubber and cement paste.
155 citations
TL;DR: In this paper, the authors evaluated the induction healing effect of steel wool reinforced porous asphalt concrete and found that induction heating increases the healing rate of the beams and that the healing is highly micro-strain-dependent with higher healing rate under high microstrain level.

TL;DR: In this paper, a sedimentological core and petrographic characterisation of samples from eleven boreholes from the Lower Carboniferous of Bowland Basin (Northwest England) is presented.
Abstract: Deposits of clastic carbonate-dominated (calciclastic) sedimentary slope systems in the rock record have been identified mostly as linearly-consistent carbonate apron deposits, even though most ancient clastic carbonate slope deposits fit the submarine fan systems better. Calciclastic submarine fans are consequently rarely described and are poorly understood. Subsequently, very little is known especially in mud-dominated calciclastic submarine fan systems. Presented in this study are a sedimentological core and petrographic characterisation of samples from eleven boreholes from the Lower Carboniferous of Bowland Basin (Northwest England) that reveals a >250 m thick calciturbidite complex deposited in a calciclastic submarine fan setting. Seven facies are recognised from core and thin section characterisation and are grouped into three carbonate turbidite sequences. They include: 1) Calciturbidites, comprising mostly of highto low-density, wavy-laminated bioclast-rich facies; 2) low-density densite mudstones which are characterised by planar laminated and unlaminated muddominated facies; and 3) Calcidebrites which are muddy or hyper-concentrated debrisflow deposits occurring as poorly-sorted, chaotic, mud-supported floatstones.

TL;DR: In this article, an encapsulated healing agent was embedded in the mortar matrix to obtain self-healing properties, and upon crack appearance, the capsules break and the healing agent is released, causing crack repair.
Abstract: It has been estimated that, in Europe, 50% of the annual construction budget is spent on rehabilitation and repair of the existing structures [1] . Therefore, autonomous crack healing of concrete, a construction material that is highly susceptible to cracking, would be desirable. In this research, an encapsulated healing agent was embedded in the mortar matrix to obtain self-healing properties. Upon crack appearance, the capsules break and the healing agent is released, causing crack repair. By means of Computed Tomography and visual observation of the crack faces, filling of the cracks with healing agent was observed. It was seen that more than 50% of the original strength and stiffness could be regained after self-healing. It was also found that the water permeability could be reduced by a factor 102 to 104 due to autonomous crack healing. As a consequence, the proposed technique may be used for partial restoration of concrete properties after cracking.

TL;DR: In this article, it is explained that the changes in the self-healing rates with temperature can be related by means of the Arrhenius equation, and an apparent activation energy for healing is needed.
