通過上述研究工作,得到了如下具有創新性研究成果: ( 1 )首次在國內提出和運用軟溶液制備工藝技術進行無機功能薄膜材料的制備研究;首次在國內採用室溫恆電流電化學技術直接在金屬基底(鉬片和鎢四川大學博士學位論文片)制備了白鎢礦結構的鋁酸鹽、鎢酸鹽薄膜;首次在國內採用水熱合成技術在欽金屬片上直接沛叮備了鈣欽礦結構的欽酸鹽薄膜。The major performances of concrete and mortars, which are mixed with different quantities of expansion admixtures under the same mix proportions, are studied systematically and deeply in this work. sulphoaluminate mixed with a type of new expanding component by use of the composite methods are studied in the laboratory, and some achievements have been obtained. the service conditions, the characteristics and the shortcomings of expansion admixture in the concrete engineering are analyzed and summarized based on literatures, and the expanding mechanism of concrete is discussed
本文試圖從膨脹劑不同摻量研究其對混凝土和砂漿主要性能的影響,進行了一系列宏觀力學性能試驗研究;利用差熱分析( dta ) 、掃描電子顯微鏡( sem )等分析手段對鈣礬石等水化產物的結晶和生成量、形貌特徵進行微觀分析;並採用復合方法摻加新型膨脹組分對硫鋁酸鹽類膨脹劑( uea )進行了改性試驗研究,根據多因素模糊綜合評價方法就各類膨脹劑的主要性能進行綜合評價,得出摻加新型膨脹組分pt的膨脹劑性能較優,取得了明顯的效果。The addition of aluminum sulfate caused the chemical shrinkage of cement mortar to reduce a little, but induced net plasma self - shrinkage to grow into expansion. that reason was that ettringite was produced by reaction between aluminum sulfate and hydration products
硫酸鋁摻入水泥中,可以使水泥漿的化學收縮有少量的減少,但可以使水泥凈漿的自收縮改變為膨脹效應,這是因為其與水泥水化的生成物反應生成了鈣礬石。The results show that : the fillers of sio2 based investment consist of sio2, al2o3 and mgo, and the binder is nh4h2po4 for sio2 based investment, the bulk density and the compression strength decrease, the apparent porosity and the thermal expansion increase, when the specimens are heated to 900 ; the fillers of al2o3 based investment consist of al2o3 and mgo, and the binder is nh4h2po4 ; for al2o3 based investment, the bulk density decreases and the apparent porosity increases when the specimens are heated to 900 ; the fillers of mgo based investment consist of mgo and al2o3, and the binder is ca cement ; for mgo based investment, the compression strength decreases and the thermal expansion increases greatly when the specimens are heated to 900
結果表明:氧化硅系包埋料的骨料是氧化硅、氧化鋁、氧化鎂,結合劑為磷酸二氫銨,其900鍛燒后顯氣孔率增加,體積密度下降,耐壓強度降低,熱膨脹增大;氧化鋁系包埋料的骨料是氧化鋁和氧化鎂,結合劑為磷酸二氫銨,其900燒后顯氣孔率增加,體積密度下降,熱膨脹變化不大;氧化鎂系包埋料的骨料是氧化鎂和氧化鋁,結合劑是鋁酸鈣水泥,其900燒后耐壓強度明顯降低,熱膨脹明顯增大。The hydration characteristics and hydration dynamics of c11a7 cacl
