摘要巴東長江公路大橋橋面鋪裝，通過採取預埋橋面粘接鋼筋、噴塗無機界面粘結劑、用微膨脹劑替代部分水泥、在混凝土中摻入適量的聚丙烯纖維等措施來提高橋面板與鋪裝層間的界面粘結強度和給橋面抗裂增韌。The expansion agents can only make up the shrinkage to some extent, and the compensation effects would be reduced when the retardener and fly - ash are used. the expansion agents are not panaceas to avoid the shrinkage cracking as expansion can also reduce the concrete soundness. under bad curing condition, the polypropylene fibrillated film fiber can improve concrete ' s anti - crarking property, while the nominal steels have very unobvious effects. to reduce the concrete shrinkage thus avoid the cracking, the former factors must all be taken into account in concrete proportion design to develop sound concrete
研究結果表明，水泥的品種和用量是影響混凝土收縮值的主要因素之一，當混凝土中水泥用量超過470kg / m ~ 3時，混凝土的收縮值超過400 10 ~ （ - 6 ） ，在約束狀態下存在高開裂風險；採用細砂使混凝土單位用水量顯著提高，收縮值也大幅增加；優質粉煤灰總體上能抑制混凝土的收縮，以超量方式摻入其抑制作用更加明顯，但粉煤灰混凝土早期的粘聚性較差，應注意養護，以免失水產生龜裂；早強減水劑和緩凝減水劑都會使混凝土收縮值增加；膨脹劑只能補償混凝土部分收縮，同時受緩凝劑和粉煤灰的抑制，而且膨脹使混凝土的體積安定性增加了不確定因素，膨脹劑不是解決混凝土收縮裂縫的良方。Following is the factors ideating with the surface of old concrete in different way ( including brushing surface, chiseling surface, cleaving surface ), adherence agent ( including cement slurry, cement sand slurry, cement slurry with the u expansion agent ), the freeze - thaw circulation times and air - entraining. as a result, we found that the roughness influence on the adhesion capability of the new on old concrete to a large degree. the larger rougeness is, the larger the splitting tensile strength on the adhension face is. the kind of adhesion agent is also influence on the adherence capability of new on old concrete. the circulation times of freez - thaw have a large influence on the splitting tensile strength of adherence face of new on old concrete. the analysis of tests give some advices to the practical engineering
主要考察了老混凝土表面不同處理方式（刷毛面，鑿毛面，劈裂面） 、界面粘結劑類型（水泥凈漿，水泥砂漿， u型膨脹劑水泥漿） 、凍融循環次數等對新老混凝土粘結面劈拉強度的影響，以及凍融作用下新混凝土加氣對粘結面劈拉強度的影響。試驗結果表明，粗糙度對新老混凝土粘結性能有重要影響，隨著粘結面粗糙度的增大，粘結面劈拉強度不斷增加；界面粘結劑類型對新老混凝土粘結性能有一定影響，在凍融作用下， u型膨脹劑水泥漿粘結效果不如水泥凈漿和水泥砂漿；凍融循環對粘結面劈拉強度有較大影響，加氣能明顯改善新老混凝土粘結面的抗凍能力。The surface area of crystalline clay minerals is highly dependent on the extent of lattice expansion.
結晶粘土礦物的表面積主要依賴于晶格膨脹的程度。The lack of fine fractions in the expanded clay necessitates the addition of other aggregates.
