礦棉裝飾吸聲板，是集裝飾、吸聲隔音、防火阻燃、隔冷絕熱、節能絕緣八大特點於一體的高級裝飾（輕體建築）材料。 -
Generally speaking activity of steel - making slag is higher than first grade fly ash. influence of special surface and particle morphology of steel - making slag powder on cementitous property is studied by experiment. results show that cementitous property of steel - making slag powder increase with increase of its special surface, but increase of cementitous property is not obvious when its special surface is beyond 500 m2 / kg
實驗結果表明，提高比表面積可提高鋼渣粉的膠凝性能，但當比表面積超過500m ~ 2 kg時，鋼渣粉的膠凝性能提高已不顯著，鋼渣粉的最佳比表面積應控制在450 500m ~ 2 kg之間；比表面積相近時，表面有細小顆粒吸附且顆粒圓形度高的鋼渣粉有相對較高的膠凝性能。 -
In this paper, the so preparing self - compacting concrete with low and middle strength using super fine mountain sand artifical sand and phosphorus slag is studied systemically. through the study the influence of the shape, the proportion of the dust and the grade of sand to the workability and the mechanical property of self - compacting concrete, it is found that super fine mountain sand artifical sand are not suit to prepare low and middle strength self - compacting concrete, but when they are combined and the additive and assistant band material are used, c20 - c40 high performance self - compacting concrete is prepared ; the corresponding additive is developed to solve the delamination caused by the low proportion of banding material ; the evaluating system for the workability of low and middle strength self - compacting concrete is built ; the controlling method for production, construction and curing was set up. and the result of the research is applied into several projects
通過分析特細山砂和機制砂的顆粒形態、粉末含量、顆粒級配等特性對自密實混凝土的工作性能和力學性能的影響，發現特細山砂、機制砂不宜單獨用於配製中低強度等級自密實混凝土，宜將特細山砂和機制砂進行合理復配，並選擇合適的外加劑和礦物摻合料，優化配合比設計，可生產c20 c40中低強度等級自密實高性能混凝土；研製開發出了具有高效減水、保塑、抗離析功能的外加劑，有效解決了中低強度等級自密實混凝土由於膠凝材料用量少而出現的離析、泌水問題；應用正交設計方法，對因素和水平進行合理選擇，確定了生產中低等級自密實混凝土的最優配合比；建立了中低強度等級自密實混凝土的工作性評價體系；提出了生產、施工及養護的質量控制技術方法。 -
The impermeability experiment under the conditions of high hydraulic pressure in long time shows that the impermeability grade of acic is further beyond p40 and that the steel slag series of acic is better than the fly ash ones
高水壓滲透實驗表明中低標號鋼渣防滲抗裂混凝土抗滲標號高於p40 ，優于同摻量粉煤灰混凝土，滿足深水條件下混凝土的抗滲要求。 -
As a new mineral additive of cement and concrete, ground steel - making slag powder has quite high activity and its activity is obvious higher first grade fly ash and close to blast furnace slag. furthermore, its distribution is very wide and quantity is quit plenty in our country
磨細鋼渣粉作為一種新的水泥混凝土摻合料，它的活性明顯優於一級粉煤灰，與礦渣活性不相上下，而且分佈較廣，數量較多，有較高的應用與研究價值。
