以水玻璃,氟硅酸钠为胶结剂的耐酸混疑土,不但具有良好的耐酸性(除HF及300*C的H_3PO_4外)耐水性,耐冷热急变和优良的抗冲击性,而且对强氧化性酸和高温稀酸均有很好的稳定性。 尽管水玻璃型耐酸混凝土,还具有所用材料来源充足,较其它合成非金属材料价格低的优点。但是,其最大缺陷是既不耐碱, The acid-resisting soil with water glass and sodium fluorosilicate as the binding agent not only has good acid resistance (except HF and H_3PO_4 of 300*C), but also has water resistance, rapid change resistance to heat and cold, and excellent impact resistance. Strong oxidizing acid and high temperature dilute acid have good stability. Although the water glass type acid-proof concrete also has a sufficient source of materials, it has the advantage of lower price than other synthetic non-metal materials. However, its biggest drawback is that it is neither alkali-resistant,
