12月(yue)13日，中國建筑(zhu)工程總公司所屬中建西部建設自主(zhu)研(yan)發的“寬溫域聚羧酸減水劑合成技術(shu)的開發與應用”，中建三局研(yan)發的“建筑(zhu)工業化混凝土預制構件生(sheng)產線(xian)研(yan)究(jiu)與應用”經湖(hu)北(bei)省住建廳鑒定，達到國際先進(jin)水平。
聚羧酸減(jian)水(shui)劑(ji)(ji)作為(wei)一(yi)種新型(xing)高(gao)性能減(jian)水(shui)劑(ji)(ji)，有著摻量低、減(jian)水(shui)率(lv)高(gao)、坍(tan)落度損失小等優點，已在(zai)施(shi)工(gong)(gong)中(zhong)(zhong)廣泛應(ying)用(yong)(yong)，但(dan)目前(qian)都(dou)是在(zai)較高(gao)溫(wen)度下(xia)合(he)成，工(gong)(gong)藝(yi)復雜、能耗較高(gao)。“寬溫(wen)域聚羧酸減(jian)水(shui)劑(ji)(ji)合(he)成技術的開發(fa)與應(ying)用(yong)(yong)”實現了(le)5-50℃變溫(wen)條件下(xia)聚羧酸減(jian)水(shui)劑(ji)(ji)的可控合(he)成，打破了(le)長期以來的加熱引發(fa)合(he)成的固定模式，實現了(le)常溫(wen)自發(fa)反(fan)應(ying)，整個合(he)成過程中(zhong)(zhong)無(wu)需加熱，工(gong)(gong)藝(yi)簡(jian)單，能耗低，無(wu)“三廢”排放，且產品性能穩定，可滿足不同混凝土(tu)的工(gong)(gong)作性能和使用(yong)(yong)要求，具(ju)有顯著的經濟和社會(hui)效益。
