High-thermal-conductivity cement mortar for improving temperature nonuniformity of wave-absorbing concrete pavement and preparation method of high-thermal-conductivity cement mortar
The invention discloses high-thermal-conductivity cement mortar for improving temperature non-uniformity of a wave-absorbing concrete pavement and a preparation method of the high-thermal-conductivity cement mortar, and a certain amount of carbon fibers and graphite are added as fillers to prepare the high-thermal-conductivity cement mortar when the cement mortar is prepared. According to the microwave-absorbing concrete, the cement mortar is subjected to rapid heat conduction in the microwave-absorbing concrete, heat in the concrete can be effectively transferred from a high-heat area to a low-heat area in a short time, the temperature difference in the concrete is effectively reduced, the surface temperature gradient of the concrete is reduced, and heating is uniform. Under the condition, when microwave deicing is carried out on the wave-absorbing concrete pavement, the high-thermal-conductivity mortar in the wave-absorbing concrete pavement enables the wave-absorbing concrete pavement to be uniformly heated, so that the influence of temperature stress generated in the long-term deicing process in winter on the deterioration of the service performance of the wave-absorbing concrete pavement is reduced, and the service life of the wave-absorbing concrete pavement is prolonged.
本发明公开了改善吸波混凝土路面温度不均匀性的高导热水泥砂浆及制备方法，本发明在制备水泥砂浆时加入一定量的碳纤维和石墨，作为填料制备高导热水泥砂浆。使水泥砂浆在吸波混凝土内部进行快速的热量传导，可以在短时间内有效的将混凝土内部的热量有高热量地区传递到低热量地区，有效地减小了混凝土内部的温差，是其表面温度梯度减小，受热均匀。在这种情况下，当吸波混凝土路面进行微波除冰时，其内部的高导热砂浆使吸波混凝土路面受热均匀，从而降低在冬季长期除冰过程中产生的温度应力对其使用性能劣化的影响，并延长其使用寿命。
