摘要基於緊密堆積和顆粒級配理論，研製了一種以工業漂珠為減輕劑、以超細膠凝材料為增強劑的新型低密度、高強度防氣竄水泥漿體系。With the very low water to cement ratio, rpc has ultra - high strength high ductility and low permeability. in this paper, the compressive strength of rpc can reach to a high point with the number approximately 135mpa. as illustrated from the study results, we can approve some fundamental conclusions : there are big effects on rpc with deferent kinds and properties of raw materials and deferent curing conditions ; stress - strain curve shows the process of destroy with rpc samples ; x - ray diffraction analysis indicates that heat treatment at temperatures 90 accelerate the hydration of rpc sharply, therefore, mechanical and microstructural properties of rpc are highly dependent on heat treatment ; it is believed that rpc materials have excellent resistance to chloride permeability ; during the heat treatment, the shrinkage of rpc developed quickly because of chemical reactions ; the rpc with slag mostly has the advantage of rpc without slag about resistance to solutions corrosion
研究結果表明：通過對rpc各組分摻量變化的研究，可以找到rpc的最優配合比；試件成型后的熱養護制度對rpc的性能影響巨大； rpc的抗壓應力?應變曲線可以反映出試件受破壞時微裂紋的擴展情況，剛纖維的摻入可以大幅改善rpc的韌性； rpc在成型后存在較大的收縮，而其中的化學收縮要遠遠大於乾燥收縮； rpc具有很強的抗氯離子滲透性能，漿體的密實度很高；通過x射線衍射實驗，可以發現rpc的膠凝體中ch晶體已經幾乎不存在，膠凝體主要由c - s - h凝膠和未水化水泥顆粒組成；在抗溶液侵蝕的實驗中，摻礦渣rpc的抗溶液侵蝕性能在絕大多數情況下要好於不摻礦渣試件，酸、堿溶液和浙江工業大學碩士學位論文摘要一些鹽溶液都會對rpc的結構產生侵蝕作用，但是機理各有不同。Analytical solution of the nearest surface spacing between neighboring binder grains in fresh cement paste
新拌水泥漿體中鄰近膠凝材料粒子表面最近間距分佈的解析解The study results indicated that, arranged in the order of magnitude, the degrees of the effects on the cementing strengths of the two interfaces were the system, emulsion, main emulsifier, fluid loss control agent and white oil respectively ; the cementing strength would be doubled and redoubled after being cleaned by preflush, especially by the system, emulsion and fluid loss control agent ; and, along with the increase in the mix slurry ratio, the initial and final set times of slurry would be obviously lengthened and the compressive strength of bond cement would be remarkably reduced or the slurry wouldn ' t be even set
