Technical and economical analysis on recycled concrete with composite aggregate 再生復(fù)合骨料混凝土的技術(shù)經(jīng)濟(jì)分析
Study on high strength low auto - shrinkage concrete with composite aggregate - auto - shrinkage of high strength concrete with composite aggregate 高強(qiáng)低自收縮復(fù)合骨料混凝土的研究之二
Aminobenzenesulfonic acid super - plasticizer is selected though cement paste test , which be provided with high water - reducing property , low slump loss and good compatibility with cement . according to the request of super high early strength , admixture rf is obtained though tests to compare performances of different accelerators and admixtures . experimental research and analysis are carried out on coarse aggregate ' s grain - size effect and composite aggregate ' s bulk - density to take sensitivity of coarse aggregate into account 通過(guò)水泥凈漿試驗(yàn)比較選擇了減水率高、坍落度損失小、與水泥適應(yīng)性好的氨基苯磺酸鹽高效減水劑;針對(duì)超早強(qiáng)的性能要求,試驗(yàn)比較了不同早強(qiáng)劑及早強(qiáng)性摻合料的性能表現(xiàn),研制了早強(qiáng)性能顯著、與高效減水劑和水泥相容性較好的rf摻合料;考慮到修補(bǔ)混凝土對(duì)粗集料粒徑的敏感性,對(duì)粗集料粒徑效應(yīng)及混合集料堆積密度進(jìn)行試驗(yàn)研究與分析;并對(duì)修補(bǔ)混凝土的抗折、抗壓、新老界面粘結(jié)強(qiáng)度以及抗凍性等進(jìn)行了試驗(yàn)研究。
