在混凝土中加入粉煤灰、矿粉等活性矿物掺合料,不仅可以这些工业废渣的再利用问题 ,有利于环境保护,还能够节约资源 、降低能源消耗, 同时还能够改善混凝土的工作性、提高抗压强度和耐久性能。混凝土生产中使用粉煤灰和矿粉, 能有效保护环境的同时改善混凝土工作性, 降低混凝土成本。

Adding active mineral admixtures such as fly ash and mineral powder to concrete can not only solve the problem of reusing these industrial waste residues, which is beneficial for environmental protection, but also save resources, reduce energy consumption, and improve the workability, compressive strength, and durability of concrete. The use of fly ash and mineral powder in concrete production can effectively protect the environment while improving the workability of concrete and reducing its cost.

　　矿粉作用

Mineral powder action

　　1、节约水泥用量 30-60% （包括水泥砂浆），降低水泥和混凝土工程成本。

1. Save 30-60% of cement usage (including cement mortar) and reduce the cost of cement and concrete engineering.

　　2、具有火山灰作用，增加混凝土抗压、抗拉、抗弯、抗剪强度。

2. It has the effect of volcanic ash, increasing the compressive, tensile, flexural, and shear strength of concrete.

　　3、显著降低混凝土水化热，改善混凝土的和易性，减少离析和泌水，减小大体积混凝土温差变化及内应力，抑制温差而产生的裂缝。

3. Significantly reduce the hydration heat of concrete, improve its workability, reduce segregation and bleeding, reduce temperature differences and internal stresses in large volume concrete, and suppress cracks caused by temperature differences.

　　4、能够抑制碱骨料反应，显著地提高了混凝土抗碱骨料反应的能力。

4. It can suppress the alkali aggregate reaction and significantly improve the ability of concrete to resist alkali aggregate reaction.

　　5、能以微集料的形式存在于混凝土中，改善混凝土中的孔结构，使孔径得以细化和均化，提高混凝土的抗渗性、抗冻融性和耐久性。

5. It can exist in the form of micro aggregates in concrete, improve the pore structure of concrete, refine and homogenize the pore size, and enhance the impermeability, freeze-thaw resistance, and durability of concrete.

　　6、可以显著减少水泥混凝土的泌水量，改善水泥混凝土的和易性。

6. It can significantly reduce the bleeding of cement concrete and improve its workability.

　　7、可有效提高水泥混凝土抗海水和淡水的侵蚀性能，抵抗硫酸盐的侵蚀。特别适用于抗海水工程、地下工程和路面工程。

7. It can effectively improve the corrosion resistance of cement concrete to seawater and fresh water, and resist sulfate corrosion. Especially suitable for seawater resistant engineering, underground engineering, and pavement engineering.

　　8、用水量不变的情况下，可配制塑性混凝土，避免因钢筋密集，振捣不善而发生质量问题。在同一条件下，能使混凝土呈流态状入模，减少混凝土泵体、管道及模具的磨损，延长其使用寿命。

8. Under the condition of constant water consumption, plastic concrete can be prepared to avoid quality problems caused by dense steel bars and poor vibration. Under the same conditions, it can make the concrete flow into the mold, reduce the wear of the concrete pump body, pipeline, and mold, and extend its service life.

　　9、可配制砌筑，抹灰水泥砂浆和低标号水泥。在满足强度要求的情况下，不但可节约水泥，同时提高了施工可操作性。

9. Can be used to prepare masonry, plastering cement mortar, and low-grade cement. Under the condition of meeting the strength requirements, not only can cement be saved, but also the operability of construction is improved.

　　10、适合于制作环境相容型水泥基材料和高性能混凝土的掺合料。

10. Suitable for producing environmentally compatible cement-based materials and admixtures for high-performance concrete.
