礦渣微粉技術
江蘇華冶環保工程有限公司所屬的冶金工程部專門從事礦渣微粉工程設計、工程總承包。公司擁有雄厚的技術.實力,同時也加工制造礦渣微粉系統中除中速磨外的全部主要設備和自動化控制系統。
礦渣微粉是高爐水渣經過研磨得到的一種超細粉末。
其化學成分主要是SiO2、AI2O3、 CaO、 MgO.Fe2O3、TiO2、 MnO2等;含有95%以上的玻璃體和硅酸二鈣、鈣黃長石、硅灰石等礦物，與水泥成份接近。礦渣微粉具有超高活性，用作水泥和混凝土的好的摻和料，是一種新型的綠色建筑材料。礦渣微粉具有潛在水化活性。當與水泥混凝土混合時，活性SIO2.AI203與水泥中C3S和C2S水化產生的Ca(OH)2反應，進-步形成水化硅酸鈣產物，填充于水泥混凝土的孔隙中，大幅度提高水泥混凝土的致密度，同時將強度較低的Ca(OH)2晶體轉化成強度較高的水化硅酸鈣凝膠，顯著改善了水泥和混凝土的一系列性能。
礦渣微粉具有潛在水硬性。礦渣中含有硅酸鹽、鋁酸鹽及大量含鈣的玻璃質(如C2S、CAS2、C2AS、C3A.C2F和CaSO4等)，具有獨立的水硬性，在CaO與CaSO4的激發作用下，遇到水就能硬化，通過細磨后，硬化過程大大加快。
與硅酸鹽水泥按比例混合，生產高性能礦渣水泥。細度為400~ 450m2/kg的礦粉，可配制425, 425R礦渣硅酸鹽水泥;細度為450~500m2/kg的礦粉，可配制525,525R礦渣硅酸鹽水泥。
作為混凝土摻和料，等量取代部分水泥(20%~70%)，耐久性、高性能混凝土。
Slag Powder Technology
Jiangsu Huaye Environmental Project Co., Ltd. belongs to the Metallurgical Engineering Department specializing in slag powder engineering design, project general contract. The company has strong technical strength, at the same time it also processes and manufactures all the main equipment andautomatic control system except medium grinder in the slag powder system.
Slag fine powder is a kind of ultra-fine powder obtained by grinding blast furnace slag.
lts chemical composition is mainly SiO2, Al2O3, CaO, MgO, Fe2O3, TiO2, MnO2 etc., and containsmore than 95% vitreous and minerals such as dicalcium silicate, calcium feldspar, wollastonite and so on,which is close to the cement composition. Slag fine powder is a new kind of green building material which is used as high quality admixture of cement and concrete because of its ultra- high activity. Slag fine powderhas potential hydration activity When mixed with cement concrete, active SiO2, Al203 react with Ca(OH) 2produced by hydration of C3S and C2S in mortar to form hydrated calcium silicate product, which is flled inthe void of cement concrete. The compactness of cement concrete is greatly increased, and the Ca(OH) 2crystal with lower strength is converted into hydrated calcium silicate gel with higher strength, whichimproves a series .of properties of cement and concrete.
Slag powder has potential hydraulic properties. Slag contains silicate, aluminate and a large amount ofcalcium- containing glass (such as C2S, CAS2, C2AS, C2A, C2F and CaSO4, etc.) and has independenthydraulic properties. Under the excitation of CaO and CaSO4, the water can be hardened after finegrinding. The hardening process is greatly accelerated.
High performance slag cement is produced by mixing with Portland cement in proportion. 525,525Rslag Portland cement can be prepared with fineness of 400~ 450m2/kg ore powder.
As a concrete admixture, the cement (20% ~ 70%) is replaced by the same amount to prepare highstrength, durability and high performance concrete.
