高鋁水泥簡介
高鋁水泥又稱為礬土水泥,耐火水泥,鋁酸鹽水泥,統稱為鋁酸鹽水泥,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,高鋁水泥常為黃或褐色,也有呈灰色的。
石嘴山市金林剛玉耐火材料有限公司生產的高鋁水泥具有快硬、早強、耐腐蝕、耐高溫的水硬性膠凝材料;它既是一種優質的建筑材料,也是一種膠凝性散狀耐火材料,在冶金、建材、石油化工、電力、食品等行業有著廣泛的應用。
高鋁水泥特點
1、細度:水泥顆粒越細,比表面積越大,水化反應越快越充分,早期和后期強度都較高。國家規定:比表面積應大于300平方米/千克,否則為不合格。
2、凝結時間:為保證在施工時有充足的時間來完成攪拌、運輸、成型等各種工藝,水泥的初凝時間不宜酞短;施工完畢后,希望水泥能盡快硬化,產生強度,所以終凝時間不宜酞長。硅酸鹽水泥的初凝時間不得早于45分鐘,終凝時間不得遲于390分鐘。
3、體積安定性:水泥漿體在凝結硬化過程中體積變化的均勻性稱為水泥的體積安定性。如體積變化不均勻即體積安定性不良,容易產生翹曲和開裂,降低工程質量甚至出現事故。
4、抗硫酸鹽侵蝕性能強:水化過程不析出游離氫氧化鈣而是生成氫氧化鋁凝膠,在顆粒表面形成保護膜,在后期晶體轉化過程中抗侵蝕性有所降低。
5、耐高溫性好:高鋁水泥可作為耐熱混凝土的膠結材料,配置成耐熱混凝土。
高鋁水泥應用
金林高鋁水泥又稱為鋁酸鹽水泥,耐火水泥,相當于625#水泥,因其具有優良的快凝,高強,耐高溫之特點, 強度可達80,耐火度可達1450度,耐火混凝土強度可達55MPa,是工業窯爐工程中 的高溫結合劑材料之一。
1、配制不定形耐火材料。
2、配制石膏礬土膨脹水泥、自應力水泥等特殊用途的水泥。
3、搶建、搶修、抗硫酸鹽侵蝕和冬季施工等特殊需要的工程。
高鋁水泥包裝及運輸
1、包裝袋為防潮袋,每袋重50kg(也可按客戶要求包裝)。
2、運輸儲存期間防止包裝破損,以免漏失或混入雜物。
3、水泥在運輸與存儲時,不得受潮和混入雜物,不得與其他品種水泥混合存放。
4、運輸方式根據客戶需求安排。

High alumina cement
Also known as alumina cement, high alumina cement refractory cement, aluminate cement, collectively known as aluminate cement, 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. High alumina cement is often yellow or brown, and gray. Shizuishan Jin Lin corundum refractories co., LTD., the production of high alumina cement has a rapid hardening, early strength, corrosion resistance, resistance to high temperature of the water rigid gelled material; It is a kind of high-quality building materials, is also a kind of loose refractory for gelling property, in metallurgy, building materials, oil chemical, electric power, food and other industries has been widely used.
Characteristics of high alumina cement
1, fineness, cement particle is fine, the bigger the specific surface area, the faster the hydration reaction more fully, the early and late strength is higher. The provisions of the state: the specific surface area should be more than 300 square meters/kg, otherwise is unqualified.
2, setting time, in order to guarantee the construction have enough time to complete mixing, transportation, forming a variety of craft, such as the initial setting time of cement shoulds not be too short; After the completion of the engineering project, the hope cement hardening, as soon as possible to produce strength, so the final setting time shoulds not be too long. The initial setting time of Portland cement shall not be earlier than 45 minutes, final set time not later than 390 minutes.
3, volume stability, water slurry uniformity of volume change in the process of condensation sclerosis called the volume stability of cement. Such as volume change uneven or volume stability, prone to warping and cracking, reduce the engineering quality and even an accident.
4, sulfate attack resistance is strong, hydration process instead of free calcium hydroxide precipitation generated aluminum hydroxide gels, the particles form a protective film. Later in the crystal transformation in the process of the erosion resistance decreases.
5, good high temperature resistance, high alumina cement can be used as heat resistant concrete cementitious materials, configured to heat resistant concrete.
High alumina cement application
Jin Lin alumina cement is also known as aluminate cement, refractory cement, the equivalent of 625 # cement, because of its excellent fast setting, high strength, high temperature resistance characteristic, a day strength can reach 80, up to 1450 degrees refractoriness, refractory concrete strength can reach 55 mpa, is the excellent high temperature industrial kiln project one of binder materials.
1. Preparation of monolithic refractories.
2. Make plaster alumina expansive cement, self-stressing cement cement and other special purposes.
3. The scrambling, repair, resistance to sulfate erosion and winter construction engineering and other special needs.
