摘要
本文介绍矿渣粉的试验研究和应用情况,试验研究表明:在混凝土中掺入部分矿渣粉,对混凝土在长时间内保持良好的工作性能,对降低水化热、减少收缩裂缝非常有利,矿渣粉可以改善硬化后混凝土的力学性能、抗渗性能和抗碳化性能等。矿渣粉在京福高速公路三明段混凝工程中的应用效果良好,具有较强的应用价值。
The experimental study of slay powder and its application is introduced, it shows that mixing slay powder partly will be very favorable for concrete to keep good workability within long time, to reduce heat of hydration and shrinking crack, the slay powder can improve the mechanics performance, impervious performance and carbonization - resistance performance etc. of concrete after hardening. The application result of the slay powder in Sanming Section Concrete Project of Jingfu Expressway is good, it has perfect application value.
