Phase-change temperature-control internal curing functional aggregate for high-strength concrete and preparation method of phase-change temperature-control internal curing functional aggregate
The invention discloses a phase-change temperature-control internal curing functional aggregate for high-strength concrete and a preparation method of the phase-change temperature-control internal curing functional aggregate, and belongs to the technical field of building materials. The preparation method comprises the following steps: preparing raw material powder from carbon fibers, graphite powder, super absorbent resin, fly ash, phosphorus slag powder, slag powder and quick lime in proportion, and preparing raw material liquid from polyacrylamide, saturated clarified lime water and an additive; the inclination angle is adjusted, and prepared raw material powder and granular paraffin are put into a disc type ball forming mill; adjusting the water yield and angle of a water spraying device, and adding the prepared raw material liquid into a water storage tank; the number of revolutions is adjusted, a disc type ball forming mill is started, the raw material powder and the particles rotate in a disc, the raw material liquid is sprayed out through atomization, and the granular paraffin gradually condenses the raw material powder and the raw material liquid and rolls into balls; and airing the prepared spherical object, and then transferring into a curing room for curing. The problem of cracks caused by shrinkage and high temperature is effectively solved when the concrete is applied to high-strength concrete.
本发明公开了一种高强混凝土用相变控温内养护功能骨料及其制备方法，属于建筑材料技术领域。其步骤如下：按比例将碳纤维、石墨粉、高吸水树脂、粉煤灰、磷渣粉、矿渣粉、生石灰配制成原料粉，将聚丙烯酰胺、饱和澄清石灰水、外加剂配制成原料液；调整倾斜角度，在盘式成球机中投入配制好的原料粉和颗粒状的石蜡；调整喷水装置的出水量和角度，将配制好的原料液体加入储水罐；调整转数，启动盘式成球机，原料粉和颗粒在盘中旋转，原料液通过雾化喷出，颗粒状石蜡逐渐凝聚原料粉和原料液，滚动成球；将制成的球状物晾干后移入养护室养护。其运用于高强混凝土有效解决由于收缩和温度高引起裂缝的问题。
