Description

混凝土专用辅料
技术领域
本发明涉及建筑材料，是一种混凝土专用辅料。
背景技术
目前混凝土中使用的辅料，大多数是单一组份，例如粉煤灰、硅灰或磨细矿渣粉等。它们的不足在于：粉煤灰的一级灰数量少，应用受限制，而三级灰则相对较粗，在相同坍落度下用水量较多，早期强度低；硅灰的产量少，价格昂贵，使混凝土成本较大幅度增高；磨细矿渣粉的能耗高，且难度大、生产成本高，工程的应用面较窄等。采用这些单一辅料配制混凝土，均无法使混凝土达到较高的性能。
发明内容
本发明的目的是提供一种混凝土专用辅料，它采用工业废料配制，可大量取代水泥，使配制的混凝土强度高，抗渗性能及抗冻性能好，抗碳化能力达到碳化深度比小于95％，价格柢。
本发明为实现上述目的，通过以下技术方案实现：混凝土专用辅料，按重量份计，它的组份及用量范围是：混合粉65-75份、矿渣粉6-16份、石灰石粉3-7份、石膏粉2-6份、锂矿渣粉1-3份、稀土微粉1-3份和硅灰4-8份，所述的混凝土专用辅料，混合粉采用一级、二级、三级粉煤灰按重量比1.5-2.5∶6-7∶0.5-1.5混合均匀。
所述的混凝土专用辅料，按重量份计，它的组份及用量范围是：混合粉70份、矿渣粉12份、石灰石粉5份、石膏粉2份、锂矿渣粉3份、稀土微粉2份和硅灰8份。
所述的混凝土专用辅料，按重量份计，它的组份及用量范围是：混合粉75份、矿渣粉7份、石灰石粉3份、石膏粉5份、锂矿渣粉1份、稀土微粉3份和硅灰6份。
本发明的辅料，经过各种试验知，具有如下优点：50％取代水泥、减水剂0.75％，用水量170Kg时，坍落度230mm，和易性良好；强度好，与已有混凝土相比，7天强度达70％，28天强度达到100％，抗渗高度比小于75％。同条件下，测试结果碳化深度比小于95％，并具有较好的抗渗性能，造价低，取材广泛，可大量取代水泥。
本发明辅料所述的混合粉可以是一级粉煤灰和三级粉煤灰的混合物，也可以是二级和三级粉煤灰的混合物，本发明的生产工艺为将一级、二级、三级粉煤灰分别按组份和重量要求混合均匀、备用。再将矿渣、石灰石、石膏、锂矿渣，分别粉碎、烧干，按上述组份和重量要求混合均匀后，采用粉磨机粉磨至450-750m2/Kg，最后。按本发明组份重量要求，将混合粉、稀土微粉、硅灰一同送入粉磨机混磨均匀即成为本发明产品。
