少熟料高标号复合水泥的性能

Study on properties of high strength blended cements with small amount of clinker

工业废渣用于水泥混合材的研究一直是水泥研究领域的热点问题。从实际应用看 ,活性高的混合材 ,如矿渣已得到充分的利用。而活性低的混合材 ,如粉煤灰 ,利用率较低。针对矿渣、磷渣和粉煤灰的特点 ,通过强度和孔结构测试 ,研究了少熟料高标号复合水泥。强度和孔结构研究表明 ,利用混合材的优势互补原理 。

Adding industrial refuses to cement as mixing materials is a hot topic in the cememt industry. In the practice viewpoint, high active mixing materials, such as slag have been used effectively. However, the mixing materials of low activity, have not been used effectively. Blended cements of high strength with small amount of clinker and large amount of mixing materials such as blast furnace slag, phosphorous slag and fly ash were studied in this paper. By means of analysis of strength and pore structure, results showed that blended cements of small amount clinker, have good properties, it can be made by making use of some advantages of additives and adding admixtures.
