掺矿粉混凝土配制技术研究

Mixing technolgy of mineral powder in concrete

本文介绍了掺矿粉混凝土的配制技术,重点研究了掺加矿粉对混凝土工作性和力学性能的影响,确定了在混凝土中掺加矿粉合理可行的配制方法、适宜掺量以及注意事项;建议在实际应用中采取矿粉和粉煤灰复掺的方式以充分发挥二者之间的“优势互补效应”,配制性能更为优异同时成本更为经济的混凝上,并针对矿粉和粉煤灰复掺确定了二者之间适宜的水泥取代率和复配比例。

Mineral powder in concrete shas good workability and mechanicability, it introduced the mixing technolgoy in the paper, including method, dosage and attentons. In practical application, mincral powder mixed with fly-ash can give better effects ad lower cost with the appropriate cement substitute ratio and mixture tratio..
