測試水泥的方法.水合熱.半絕熱法Methods of testing cement - part 9 : heat of hydration - semi - adiabatic method
水泥的試驗方法.第9部分:水合熱.半絕熱法Methods of testing cement - part 9 : heat of hydration - semi - adiabatic method ; german version en 196 - 9 : 2003
水泥的檢驗方法.第9部分:水合熱.半絕熱法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。The research of this text is about stopping " alkali - aggregate reaction ", reducing concretes exothermic peak, controling the internal concrete adiabatic storage and using the microexpansivity of magnesia to make up the shrinkage production in the later harden
