煤粘泥 的英文怎麼說
中文拼音 [méiniánní]
煤粘泥
英文
coal slime-
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。It is made of sand, cement and lightweight aggregate, etc. some of the lightweight aggregates include pumice, stuff, expanded clays ( haydite ), etc. lightweight aggregate concrete can provide the same strength as the normal concrete with less weight
輕骨料混凝土是一種用量較大的新型混凝土，其密度在850kg m ~ 3至1950kg m ~ 3之間，由粘土陶粒，粉煤灰陶粒等粗骨料以及常用的砂，水泥，水等材料製作而成。The equipment gives pressure to both sides and makes use of industrial wastes, slags, flying ash ， lime sand, fluvial sand and gangues with a little cement to produce the standard bricks, blind hole unburned bricks and clay - sintered bricks for all kinds of specification
該設備雙面加壓，利用工業廢渣、礦渣、粉煤灰、石粉、沙子、煤矸石等原料加少量水泥製成各種規格的標磚、盲孔免燒磚、粘土燒結磚。This machine used in crushing material in small. the material can be clay, shale, gangue, limestone, cement, iron, ore, etc
該機適用於粘土、頁巖、煤矸石、石灰石、水泥熟料、鐵礦石等物料的中細破碎。Match ratio tests are done by using cement and fly - ash as curing agent, which include making soft clay with different water content into different mixing ratio cement - stabilised clay, and mixing cement and fly ash to make different cement - fly ash stengthened clay to soft clay with ascertaining water content. afterwards unconfined compression strength is tested at different curing age. the microstructures and mechanisms of cement soil and cement - fly ash soil are studied by mean ", of x - ray and scanning electron microscope ( sem ) technology
採用水泥和粉煤灰為固化劑在室內進行其配合比試驗，對含水量不同的軟粘土製成不同摻入比的水泥土以及對含水量值固定的軟粘土製成水泥、粉煤灰摻入量分別不同的水泥-粉煤灰加固土，並在不同齡期時進行無側限抗壓強度試驗；運用x射線衍射和掃描電子顯微鏡技術，對水泥土及水泥-粉煤灰加固軟土的微觀結構和機理進行分析。By using wind - blown soil, fly ash, clay, a small amount of cement and addition agent as raw materials in this paper, the optimum dispensation formula and spreading theory about filling and pre - grouting of composite filling material were studied to have important practical significance to large filling and pre - grouting project
本文利用風積土、粉煤灰、粘土、少量水泥和其它外加劑為原材料，研究復合充填注漿材料的最佳配比及其擴散充填注漿理論，對于大型充填注漿工程具有重要的現實意義。Based on analyzing and determining basic characteristics of every raw material, the dispensation tests had been performed about clay - cement paste, fly ash - cement paste, fly ash - clay - cement paste and wind - blown soil - clay - cement paste, and their performance figures were tested systematically and obtained perfectly so that a reasonable dispensation formula was get to be used in filling project
在分析測試各種原材料基本性能的基礎上，按正交試驗設計方法，完成了粘土?水泥漿、粉煤灰?水泥漿、粉煤灰?粘土?水泥漿和風積土?粘土?水泥漿的配比試驗，並對其各項性能指標進行了系統的測試和分析，得到了可供工程應用的合理配方。分享友人
