PLS胶凝材料系统,主要采用火山灰质材料、钙镁质氧化物和硫酸盐类工业废渣混合而成。这一胶凝系统的基本原理是在碱、硫酸盐等激发剂的共同作用下,火山灰质原材料的潜在火山灰活性得到充分发挥,成为可以高掺量甚至完全替代水泥的一种胶凝材料。本文利用工业废渣——粉煤灰、电石渣及硫酸钠组成的PLS胶凝材料作为低等级农村公路路面硬化新型材料有着广阔的应用前景,不仅能大大降低工程造价,而且在节约土地、环境保护方面也具有深远意义。 PLS cementitious materials system, the main use of pozzolanic materials, calcium magnesium oxide and sulfate mixed industrial waste. The basic principle of this gelling system is that the pozzolanic activity of the pozzolanic raw material is fully exerted under the co-action of the activating agent such as alkali and sulfate to become a cementitious material capable of high dosage or even completely replacing the cement. In this paper, PLS cementitious material, which is composed of industrial waste residue-fly ash, carbide slag and sodium sulfate, has broad application prospects as a new type of material for road surface hardening of low-level rural roads. It not only can greatly reduce construction cost, but also save land and environmental protection Also has far-reaching significance.
