耐火水泥簡介
?
? ? 耐火水泥也叫鋁酸鹽水泥。鋁酸鹽水泥是以鋁礬土和石灰石為原料，經煅燒制得的以鋁酸鈣為主要成分、氧化鋁含量約50的熟料，再磨制成的水硬性膠凝材料。鋁酸鹽水泥常為黃或褐色，也有呈灰色的。鋁酸鹽水泥的主要礦物成為鋁酸一鈣及其他的鋁酸鹽，以及少量的硅酸二鈣等。

耐火水泥特點
?
? ? 鋁酸鹽水泥凝結硬化快，**達到標號強度的80以上，三天達到標號強度100 ，并且具有良好的抗凍性，抗腐蝕性，特別是高耐火度是其它水泥無可比擬的優點。

耐火水泥特點
?
? ? 1、鋁酸鹽耐火水泥具有早期強度增長率**的特性，可以制作快硬混凝土與快硬砂漿，應用于搶建、搶修、抗硫酸鹽蝕和冬季施工等特殊需要的工程。
?
? ? 2、制作耐熱混凝土與耐熱砂漿：高鋁水泥是適用于一般耐熱工程的膠凝材料。因其強度高在制作耐熱混凝土時，可多用耐火材料，故砂漿或混凝土的耐熱性能好。宜廣泛用于冶金、化工、石油、機械、建材等工業的各種窯料；
?
? ? 3、低溫施工：高鋁水泥水化快，放熱集中，低溫下比硅酸鹽類水泥快的多。5以上施工可免去蒸氣養護與防寒措施，加快工程進度。
?
? ? 4、用于抗硫酸鹽浸蝕的工程：高鋁水泥抗硫酸鹽浸蝕性能好，適用于海港工程、鹽湖地區的鐵路建設和建筑工程以及弱酸性壓水管道等；
?
? ? 5、生產其它品種水泥；以高鋁水泥為原料，可生產各種膨脹、收縮補償以及特種耐熱、耐蝕水泥。如：鋁酸鹽自應力水泥、硅酸鹽自應力水泥、石膏巖土膨脹水泥、不透水不收縮水泥、耐熱油井水泥、抗銨聚合水泥、特快硬水泥等；
?
? ? 6、其它用途：鋁酸鹽耐火水泥是生產凈水劑的主要原料其鋁含量在53以上，也是生產無機花崗巖的主要原料，還可以用于制造化學工業觸媒、防凍混凝土、防中子輻射混凝土、鑄造模型、火花塞、電氣開關減弧罩等。

Introduction of refractory cementRefractory cement is also called the aluminate cement.Aluminate cement is bauxite and limestone as raw material, after the calcination of calcium aluminate as main ingredients, alumina content is about 50 of the clinker, again into the water rigid gelled material.Aluminate cement is often yellow or brown, and gray.Aluminate cement main minerals become a calcium aluminate and other aluminum acid salt, and a small amount of dicalcium silicate , etc.Characteristics of refractory cement1, aluminate, the characteristics of refractory cement with early strength growth rate is higher, can make rapid hardening and rapid hardening cement mortar, concrete application in the scrambling, repair, resistance to sulphate corrosion and winter construction engineering and other special needs.2, production of heat-resistant concrete and heat resistant mortar: high alumina cement is applicable to general heat engineering gelled material.Because of its high strength in the production of heat-resistant concrete, multi-purpose refractory material, so the mortar or concrete heat resistant performance is good.Should be widely used in metallurgy, chemical industry, petroleum, machinery, building materials industry of all kinds of kiln;3, low temperature construction: high aluminum cement hydration, heat concentration, low temperature is larger than that of silicate cement fast.More than 5construction and protection measures in steam curing and can be avoided, speed up the construction schedule.4, used for resistance to sulfate erosion project: high aluminum cement sulfate erosion resistance performance is good, for sea port engineering, salt lake region of railway construction, and construction engineering and weakly acidic water pressure pipeline, etc.;5, and other varieties of cement production;With high alumina cement as raw materials, can produce all kinds of expansion and shrinkage compensation and special heat resistant and corrosion resistant cement.Such as: aluminate self-stressing cement, silicate, self-stressing cement, gypsum rock expansive cement, concrete impervious contractive, heat oil well cement, ammonium polymer cement resistance, express cement, etc.6, other USES: aluminate refractory cement production water purifier is the main raw material of aluminum content in more than 53, is the main material in the manufacture of the inorganic granite , can also be used in the manufacture of chemical industry catalyst, antifreeze, neutron radiation proof concrete, concrete casting model, spark plugs, electrical switch arc hood reduction etc.
