low-slag cement 中文意思是什麼
low-slag cement
解釋
低礦渣水泥-
Anti penetration of hardened mortar can reach 10 - 7cm / s. adopting sulfate - aluminum cement, phosphorus slag, flying ash, yellow slag and ect raw materials, the optimized mixture program of dmm is a3b3c2 ( cement 480 m2 / kg, phosphorus slag352 m2 / kg, activated agent 3 % ), 28 strength is low, due to cement alkality, resulting in activity of phosphorus slag and flying ash small
採用硫鋁酸鹽水泥，磷渣、粉煤灰、黃砂等原武漢理工大學碩士學位論文料配製抗滲干拌砂漿最優配料方案為: a3b3c2 （水泥比表面積4som ， / kg ，磷渣比表面積352mz / kg ，激發劑3 % ） 。 -
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。 -

( 3 ) the feasibility of manufacturing dry - mortar is discussed, replacing yellow sand with phosphor slag. ( 4 ) the feasibility of producing dry - mortar is analyzed, replacing sulphur aluminate low alkalinity cement by silicate cement. ( 5 ) study impact of the water quantity of sand on the strength of dry - mortar, and it is concluded that water quantity of sand can influence strength effectively and must be controlled seriously in production
（ 3 ）試驗研究了用磷渣替代黃砂配製干拌砂漿的可行性； （ 4 ）試驗研究了用硫鋁酸鹽低堿水泥替代硅酸鹽水泥配製干拌砂漿的可行性； （ 5 ）試驗研究了砂含水量對干拌砂漿影響，發現砂的含水量對干拌砂漿的強度影響較大，在生產中必須嚴格控制砂的含水量。
