选用粉煤灰、低活性矿渣粉、玻璃粉、磨细磷渣粉四种矿物掺合料，进行水泥胶砂试验。通过掺合料种类、掺量变化的胶砂强度对比，探索低活性矿渣粉、玻璃粉、磨细磷渣粉三种工业废渣作为矿物掺合料在建筑材料领域应用的可行性。结果表明：低活性矿渣粉、玻璃粉、磨细磷渣粉可以不同掺量地取代现供应紧张的矿物掺合料粉煤灰等制备高性能建筑材料，在早期主要发挥颗粒填充效应，在后期可以不同程度地参与水泥基材的水化反应，以缓解现有矿物掺合料的供应紧张局面。
選用粉煤灰、低活性礦渣粉、玻璃粉、磨細燐渣粉四種礦物摻閤料，進行水泥膠砂試驗。通過摻閤料種類、摻量變化的膠砂彊度對比，探索低活性礦渣粉、玻璃粉、磨細燐渣粉三種工業廢渣作為礦物摻閤料在建築材料領域應用的可行性。結果錶明：低活性礦渣粉、玻璃粉、磨細燐渣粉可以不同摻量地取代現供應緊張的礦物摻閤料粉煤灰等製備高性能建築材料，在早期主要髮揮顆粒填充效應，在後期可以不同程度地參與水泥基材的水化反應，以緩解現有礦物摻閤料的供應緊張跼麵。

Fly ash, low activated slag, glass powder and phosphorous slag were used to prepare cement-based composites in this investigation. Mechanical tests of different cement mortar samples with different mineral admixtures were executed, which were used to explore the feasibility of these industrial waste residues as mineral admixture in building materials field application. The results reveal that it is possible to use low activated slag, glass powder and phosphorous slag to replace for fly ash to produce high performance cementitious composites; filling effect at early ages and hydrating reaction at later ages for these industrial waste residues would happened. All these showed that low activated slag, glass powder and phosphorous slag would have significant importance for alleviating scarce supply of the existing mineral admixtures and promoting green production of building materials.
