在混凝土中加入粉煤灰、礦粉等活性礦物摻合料,不僅可以解決這些工業(yè)廢渣的再利用問題 ,有利于環(huán)境保護(hù),還能夠節(jié)約資源 、降低能源消耗, 同時(shí)還能夠改善混凝土的工作性、提高抗壓強(qiáng)度和耐久性能。混凝土生產(chǎn)中使用粉煤灰和礦粉, 能有效保護(hù)環(huán)境的同時(shí)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.

　　礦粉作用

Mineral powder action

　　1、節(jié)約水泥用量 30-60% （包括水泥砂漿），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，增加混凝土抗壓、抗拉、抗彎、抗剪強(qiáng)度。

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

　　3、顯著降低混凝土水化熱，改善混凝土的和易性，減少離析和泌水，減小大體積混凝土溫差變化及內(nèi)應(yīng)力，抑制溫差而產(chǎn)生的裂縫。

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、能夠抑制堿骨料反應(yīng)，顯著地提高了混凝土抗堿骨料反應(yīng)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，改善混凝土中的孔結(jié)構(gòu)，使孔徑得以細(xì)化和均化，提高混凝土的抗?jié)B性、抗凍融性和耐久性。

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、可以顯著減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蝕性能，抵抗硫酸鹽的侵蝕。特別適用于抗海水工程、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、用水量不變的情況下，可配制塑性混凝土，避免因鋼筋密集，振搗不善而發(fā)生質(zhì)量問題。在同一條件下，能使混凝土呈流態(tài)狀入模，減少混凝土泵體、管道及模具的磨損，延長其使用壽命。

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，抹灰水泥砂漿和低標(biāo)號水泥。在滿足強(qiáng)度要求的情況下，不但可節(jié)約水泥，同時(shí)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、適合于制作環(huán)境相容型水泥基材料和高性能混凝土的摻合料。

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