摘要以低?水泥和膨脹珍珠巖為主要原料,輔之以分散性良好的增強劑聚丙烯纖維,研製出一種新型吸聲材料。The influence of the type and amount of active strengthening agent, cement - blast ratio and cement dispersity have been studied to the property of fly ash blast cement
研究了活性增強劑類型及摻量、灰渣比和水泥分散度對粉煤灰礦渣水泥性能的影響。In addition, impact of superplasticizers to hydration procee were discussed thoroughly. results showed that superplasticizers improved cement hydration process. initial hydration of cement was accelerated by superplasticizers because of their high range water reducing and dispersive action. after that, hydration rate was descended as a result of more initial hydrates and absorption of superplasticizers
高效減水劑由於其高度減水分散作用,水泥初始水化速度加快,但其後由於減水劑分子的吸附及初期水化產物膜的增厚,水化速度降低,從而有利於漿體結構的密實與後期性能的發展。On the basis of theory analysis, the average transmitted light intensity ( correspond to dc value ) was determined as characteristic parameter of raw water using photoelectric method for monitoring the fluctuation of transmitted light and photometric dispersion analyzer ( pda ). the dc value was closely related to both particle concentration and surface area of sand clay simultaneously. the experimental results shows that there is an exponential function relation between dc and surface area of sand clay in unit volume water ( sp ) : dc = asbp in which a and b are empirical coefficients. then the formula of macromolecule flocculant dosage is found to be d = f ( dc ) = e ( dc ) f in which e and / are empirical coefficients and the average correlation coefficient equal to 0. 981. so the model of automatical control system of water treatment plant was established using the formula
應用透光率脈動檢測技術和光散射顆粒粒度分析儀( pda ) ,通過理論分析,將pda的輸出信號之一? ?平均透光強度(對應于dc值)作為原水的特性表徵參數, dc值可以同時反映顆粒濃度和比表面積因素的影響,試驗結果證明, dc值與單位體積水中泥沙顆粒總表面積s _ p之間具有很好的冪函數關系: dc = cs _ p ~ d ,式中c 、 d為經驗系數,進而得到了以dc值為參數的高分子絮凝劑投藥量公式: d = f ( dc ) = e ( dc ) ~ f ,式中: e 、 f為經驗系數,平均相關系數達0 . 981 ,利用所建立的公式,建立了前饋? ?后饋聯合控制的在線自動投藥模型。Dense of structure and development of final properties were benefited from retardation of hydration. in contrast, cement hydration process was controlled better by polycarboxylate superplasticizer than the other three superplasticizers owing to its stereoscopic action. and its adaptability to cement was better, by which the cement particles were
相比之下,聚羧酸鹽高效減水劑由於其良好的空間位阻效應,能夠使水泥顆粒呈完全分散狀態,與其他三種高效減水劑相比可有效控制水泥水化歷程,與水泥適應性較好。The properties of the new superplasticizer were studied by comparison with naphthyl type, including its effects on the fluidity and the slump - loss of cement paste and concrete ; its effects on the strength of the cement was also investigated. it has a good compatibility with cements of different types
