    摘 要:每年有大量的廢棄物被處理至垃圾填埋場,全球自然資源日益枯竭,二氧化碳排放問題愈發嚴峻,所有這些問題都是促使研究機構和工程界探索土木工程領域中可持續解決方案的主要動機。因此,綠色建筑建設中可持續性建材的使用是短期內必須要實現的重要目標??沙掷m發展水泥可通過用無害廢棄物代替部分熟料而減少水泥的生產。將廢棄物轉變成水泥的再生原料,是降低環境負荷、實現可持續發展的重要途徑。本文討論了水泥制造工藝環節和它對環境污染的影響以及實現可持續發展的途徑。 Abstract: There are a lot of wastes treated to a landfill each year, the world's natural resources are depleted, carbon dioxide emissions problem is more severe, all of these are the research institutions and engineering field to explore the main motivation of sustainable solutions in the field of civil engineering. Therefore, the use of sustainable building materials in green building construction is an important target which must be achieved in the short term. Sustainable development cement can reduce the cement production by using the innoxious wastes to replacing part of cement clinker. The wastes into recycled raw materials of cement is an important way of reducing the burden on the environment and achieving sustainable development. The ways to cement manufacturing process and its effect on the pollution of the environment and the implementation of sustainable development are discussed in this paper.

    摘 要:將30%質量的城市固體廢物焚燒(MSWI)底灰摻入混凝土中替代水泥,通過對底灰混凝土的收縮率,抗碳化性、抗滲性、抗凍性等進行試驗,并與普通混凝土進行對比,研究了底灰作為水泥替代物的可行性。研究結果表明,測試的垃圾焚燒底灰具有一定的火山灰活性,一定范圍內摻加底灰的混凝土具有較小的收縮率,抗碳化性、抗滲性、抗凍性能優異,底灰的引入可以改善混凝土的耐久性。 Abstract:Using 30% municipal solid waste incineration (MSWI) bottom ash to replace cement in concrete, the shrinkage, carbonation resistance, impermeability, frost resistance of the bottom ash concrete are tested. Compared with ordinary concrete, the feasibility of the bottom ash as the cement substitute is studied. The study results show that the waste incineration bottom ash has a certain ash activity. The concrete with a certain amount of bottom ash has a smaller shrinkage rate and better performances of carbonation resistance, impermeability, frost resistance. Adding the bottom ash in the concrete can improve the durability of concrete.

    摘??要:探討了材料類型、密度、含水率、測試溫度等因素對硅酸鈣板導熱系數的影響。結果表明,硅酸鈣板的結構類型不同,其導熱系數會存在較大差別;密度越小,其孔隙率相對越大,導熱系數值就會越??;導熱系數隨著含水率的增加出現先緩慢增加再迅速增加后趨于平穩的趨勢;絕干或含水率較低情況下,其導熱系數隨著平均溫度的升高而增大,且密度等級越低,增幅越大,但由于加熱法測量導熱系數的過程中存在濕分遷移效應,當含濕量超過一定值時(約8%~10%),測試平均溫度越高,其導熱系數反而越小。Abstract:Theeffectsofmaterialtype,density,moisturecontent,testtemperature,etc.onthermalconductivityofcalciumsilicateboardarestudied.Theresultsshowthatitsthermalconductivitydiffersaccordingtoitsstructureandtype.Thesmallerthedensity,thegreatertherelativeporosity,whichleadstothesmallerthermalconductivity.Thethermalconductivityincreasesslowlyatfirstandthenrapidlyincreasesandlasttendstobeconstantwiththeincreaseofmoisturecontent.Undertheconditionofabsolutelydryorlowmoisturecontentofthesample,thethermalconductivityincreaseswiththeincreaseoftheaveragetemperature,andthelowerthedensitygrade,thefasterthegrowthofthethermalconductivityis.However,duetothemoisturemigration,thehighertheaveragetesttemperature,thesmalleritsthermalconductivityis,whenthemoisturecontentexceedsacertainvalue(about8%to10%).

    摘 要:通過實驗室模擬試驗,研究了生石灰、鋁粉膏及水的用量對利用固硫灰渣生產蒸壓加氣混凝土砌塊的干密度及抗壓強度的影響。試驗結果表明:當固硫灰渣的用量較大時,生石灰的用量是主要的影響因素,其用量不應低于17%;鋁粉膏的用量對抗壓強度的降低影響較顯著,對干密度的減少影響相對較小,其用量不宜超過0.08%;在滿足砌塊生產時對料漿稠度要求的條件下,水的用量主要影響抗壓強度。 Abstract: The influences of quicklime, aluminite pastes and water in different contents on the dry density and compressive strength of autoclaved aerated blocks which are mainly made of fluidized bed combustion ashes (FBCA) are studied by experimental tests systematically. The experimental tests show that the content of quicklime is a primarily influencing factor, and it should not be under 17% when the large content of FBCA is used. The compressive strength of autoclaved aerated FBCA blocks is reduced obviously and the dry density has not been affected too much by the content of aluminite pastes. Besides, it should be noted that the content of aluminite pastes cannot exceed 0.08%. The content of water primarily influences the compressive strength of autoclaved aerated FBCA blocks when complying with the requirements of slurry consistence in blocks production.
