Municipal RPC road traffic stone material and preparation method thereof
The invention provides a municipal RPC road traffic stone material and a preparation method thereof. The road traffic stone material comprises the following components in parts by weight: 100-120 parts of cement, 40-60 parts of silica fume, 3-8 parts of fibers, 0.2-0.7 part of a defoaming agent, 0.2-0.6 part of a plastic expanding agent, 0.1-0.7 part of quartz sand, 2-3 parts of water reducing agents and 100-150 parts of water. Silica fume is doped, and silica fume particles have good sphericity and play a good lubricating role, so that the rheological property is improved, pores among particles with different particle sizes can be filled, and the purpose of densification is achieved; the quartz sand with three particle sizes is more uniform and reasonable in gradation, the particles withdifferent particle sizes can be better wrapped and embedded with one another, the compactness of the aggregate is improved, in addition, the fiber mixing amount is optimized, so that the concrete is better in flowability and better in breaking strength, and a cracking problem is basically solved. The characteristics of higher strength, higher toughness, high durability and the like are realized.
本发明提供了一种市政用的RPC路沿石材料及其制备方法，该路沿石材料包括如下重量份的组分：100‑120份水泥、40‑60份硅灰、3‑8份纤维、0.2‑0.7份消泡剂、0.2‑0.6份塑性膨胀剂、0.1‑0.7份石英砂、2‑3份减水剂和100‑150份水；本发明掺入硅灰，由于硅灰颗粒具有良好的球形，起到很好的润滑作用，从而提高流变特性，同时还能够填充不同粒径颗粒间的孔隙，达到致密的目的；本发明采用三种粒径的石英砂级配更为均匀合理，不同粒径的颗粒能够更好地相互包裹及嵌实，提高了骨料的密实度，另外通过优选纤维掺量，使得混凝土流动性更好，具有较好的抗折强度，基本解决了开裂问题，具有较高强度、较高韧性和高耐久性等特点。
