簡要介紹了國內外硫酸鉀生產及需求現狀，重點介紹和分析了我國目前應用的芒硝法、明礬石礦綜合利用法、曼海姆法和締置法的優缺點，並對我國硫酸鉀工業今後的發展提出了自己的看法。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。
