技術(shu)特點(dian)
        其(qi)原理是：該產(chan)(chan)品摻(chan)入混(hun)(hun)凝(ning)(ning)(ning)(ning)(ning)土(tu)(tu)(tu)(tu)中，由膨(peng)脹組分(fen)產(chan)(chan)生(sheng)的(de)特殊膨(peng)脹源，能同步補償混(hun)(hun)凝(ning)(ning)(ning)(ning)(ning)土(tu)(tu)(tu)(tu)各齡(ling)(ling)期(qi)的(de)不同因素引起的(de)收(shou)(shou)(shou)縮，保證了混(hun)(hun)凝(ning)(ning)(ning)(ning)(ning)土(tu)(tu)(tu)(tu)各齡(ling)(ling)期(qi)的(de)凈收(shou)(shou)(shou)縮值(zhi)(zhi)始(shi)終小于(yu)混(hun)(hun)凝(ning)(ning)(ning)(ning)(ning)土(tu)(tu)(tu)(tu)的(de)極限拉伸值(zhi)(zhi)，這樣混(hun)(hun)凝(ning)(ning)(ning)(ning)(ning)土(tu)(tu)(tu)(tu)在各齡(ling)(ling)期(qi)都處于(yu)不開裂的(de)安全狀態中；由減縮組分(fen)產(chan)(chan)生(sheng)的(de)特殊減縮源，可相應降(jiang)低(di)混(hun)(hun)凝(ning)(ning)(ning)(ning)(ning)土(tu)(tu)(tu)(tu)中各齡(ling)(ling)期(qi)的(de)收(shou)(shou)(shou)縮絕對值(zhi)(zhi)，降(jiang)低(di)混(hun)(hun)凝(ning)(ning)(ning)(ning)(ning)土(tu)(tu)(tu)(tu)中毛(mao)細孔洞的(de)表面張(zhang)力(li)，從而(er)進一(yi)步保證了混(hun)(hun)凝(ning)(ning)(ning)(ning)(ning)土(tu)(tu)(tu)(tu)各齡(ling)(ling)期(qi)收(shou)(shou)(shou)縮和(he)膨(peng)脹的(de)動態平衡，有效提高(gao)(gao)了混(hun)(hun)凝(ning)(ning)(ning)(ning)(ning)土(tu)(tu)(tu)(tu)的(de)抗(kang)裂性(xing)能；由防滲組分(fen)產(chan)(chan)生(sheng)的(de)特殊凝(ning)(ning)(ning)(ning)(ning)膠物質，有效填充(chong)和(he)阻斷混(hun)(hun)凝(ning)(ning)(ning)(ning)(ning)土(tu)(tu)(tu)(tu)毛(mao)細通道，降(jiang)低(di)各分(fen)子(zi)之間的(de)表面張(zhang)力(li)，提高(gao)(gao)混(hun)(hun)凝(ning)(ning)(ning)(ning)(ning)土(tu)(tu)(tu)(tu)組成材料界面之間的(de)粘結性(xing)能，提高(gao)(gao)混(hun)(hun)凝(ning)(ning)(ning)(ning)(ning)土(tu)(tu)(tu)(tu)的(de)密實度，使得混(hun)(hun)凝(ning)(ning)(ning)(ning)(ning)土(tu)(tu)(tu)(tu)耐腐蝕(shi)(shi)性(xing)和(he)耐化學侵蝕(shi)(shi)性(xing)得到大幅度提高(gao)(gao)。
        其(qi)優(you)點在于堿含量低(di)、膨(peng)(peng)脹率大、后期強度(du)高、干縮率小；混凝(ning)土(tu)坍(tan)落度(du)損失小，摻膨(peng)(peng)脹劑的(de)混凝(ning)土(tu)施工(gong)養護方(fang)法與規范規定的(de)普通混凝(ning)土(tu)養護方(fang)法基本相同(tong)，是一(yi)種能在工(gong)程中廣泛應用(yong)的(de)，耐久性好的(de)新型膨(peng)(peng)脹劑。
