摘要
研究了用石粉及其与矿渣复合配制早强、高强混凝土。结果表明,石粉掺量在15%以下时有利于抗压强度和抗折强度的发展。用10%的石粉和10%的矿渣的复合时,复合效应优良,当胶凝材料用量为540kg/m3时,7d抗压强度达到了90MPa,28d抗压强度在100MPa以上。
The paper studys high-strength concrete made with limestone powder and slag was studitd.The result shows that it is favorable to compressive strength and flexural tensile strength when the amount of limestone powder is below 15%.The compound of 10% limestone powder and 10% slag can exert good effect,When cementious material content is 540 kg/m3,7 d compressive strength attained 90 MPa,28 d strength is above 100 MPa.
