高铝水泥简介：

高铝水泥是以铝酸钙为主，氧化铝含量约50%的熟料，磨制的水硬性胶凝材料，属于铝酸盐类水泥。高铝水泥也是快干水泥，现在自流平水泥中可以用的快干水泥很多的，高铝、硫铝、铁铝、双快等，很多。高铝水泥和硅酸盐水泥都是属于水硬性水泥，前者的主要矿物组成是铝酸盐，后者的主要矿物组成是硅酸钙，由于矿物组成的不同，水泥的特性也不相同。

Brief introduction of high alumina cement:

High alumina cement is a clinker which is mainly calcium aluminate and about 50% of alumina content. It is a hardened cementitious material, which belongs to the aluminate salt cement. High alumina cement is also fast drying cement, now self leveling cement can be used in a lot of fast dry cement, high aluminum, aluminum, aluminum, double fast, and so on. High alumina cement and Portland cement belong to hydraulic cement. The main mineral composition of the former is aluminate, and the latter is mainly composed of calcium silicate. Due to the different mineral composition, the properties of cement are also different.

高铝水泥特性：

1、细度：水泥颗粒越细，比表面积越大，水化反应越快越充分，早期和后期强度都较高。规定：比表面积应大于300㎡/kg，否则为不合格。

2、凝结时间：为保证在施工时有充足的时间来完成搅拌、运输、成型等各种工艺，水泥的初凝时间不宜太短；施工完毕后，希望水泥能尽快硬化，产生强度，所以终凝时间不宜太长。硅酸盐水泥的初凝时间不得早于45分钟，终凝时间不得迟于390分钟。

3、体积安定性：水泥浆体在凝结硬化过程中体积变化的均匀性称为水泥的体积安定性。如体积变化不均匀即体积安定性不良，容易产生翘曲和开裂，降低工程质量甚至出现事故。

High alumina cement characteristics:

1, fineness: the finer the cement particles, the larger the specific surface area, the quicker the hydration reaction, the higher the strength in the early and late stages. The provisions of the state: the specific surface area of 300 square meters should be greater than /kg, otherwise unqualified.

2, setting time: in order to ensure that there are enough time to finish mixing, transportation, molding and other processes, the initial setting time of cement should not be too short. After completion of construction, it is hoped that cement will harden and produce strength as soon as possible, so the final setting time should not be too long. The initial setting time of Portland cement should not be as early as 45 minutes, and the final setting time should not be less than 390 minutes.

3, volume stability: the uniformity of the volume of the cement slurry in the setting and hardening process is called the volume stability of the cement. If the volume change is not uniform, that is, the volume stability is bad, it is easy to produce warpage and crack, reduce the quality of the project and even appear accident.

4、耐火水泥炉衬进行烘烤时，须注意下列事宜:

1)常温350度阶段，易引起局部爆裂，要特别注意缓慢烘烤。如在350度保温后仍有大量蒸汽冒出，仍应减缓升温速度。

2)在通风不良、水气不易排出的条件下，要适当延长保温时间。

3)当用重油烘烤时，要严防重油喷在炉衬表面，以防局部爆裂。

4)当用木柴烘烤时，直接接触火焰处往往造成局部升温过急，应加以防护。

5)对新浇捣的耐火水泥，至少要经3d后才可进行烘烤。

6)对耐火水泥炉衬的冷却也应缓慢，避免强制通风。

4. When the fire-resistant cement lining is roasted, the following matters must be paid attention to:

1) the 350 degree stage at normal temperature is the most likely to cause local bursting, and special attention should be paid to the slow baking. If there is still a large amount of steam coming out after 350 degrees of heat preservation, the heating rate should still be slowed down.

2) under the condition that the ventilation is bad and the water and gas are not easy to expelled, the heat preservation time should be extended properly.

3) when the heavy oil is baked, it is necessary to prevent the heavy oil from spraying on the lining surface to prevent local bursting.

4) when using wood baking, direct contact with the flame is often caused by local heating too fast, should be protected.

5) the newly poured fire-resistant cement should be baked at least after 3D.

6) the cooling of the refractory cement lining should also be slow to avoid compulsory ventilation.

高铝水泥用途：

高铝水泥又称为铝酸盐水泥耐火水泥，相当于625#水泥，因其具有优良的快凝，高强，耐高温之特点，强度可达80%，耐火度可达1450度，耐火混凝土强度可达55MPa,是工业窑炉工程中的高温结合剂材料。高铝水泥是配制不定形耐火材料的主要原材料。可配制石膏矾土膨胀水泥、自应力水泥等特殊用途的水泥。在抢建、抢修、抗硫酸盐侵蚀和冬季施工等特殊需要的工程中也起着中流砥柱的作用。

High alumina cement use:

High alumina cement and sulphoaluminate cement called refractory cement, the equivalent of 625# cement, because of its fast setting, high-strength, high temperature resistant characteristics, a day intensity can reach 80%, refractoriness up to 1450 degrees, refractory concrete strength up to 55MPa, is one of the high temperature binder material excellent industrial furnace engineering. High alumina cement is the main raw material for the preparation of amorphous refractory. Can be made of alumina cement, gypsum cement and other special purpose self stressing cement expansion. In the construction, repair, also has the resistance to sulfate erosion and winter construction projects and other special needs in a mainstay role.

高铝水泥包装：

水泥袋装时应采用防潮纸袋（四层普通包装纸，三层防潮纸），每袋净重50±1公斤。也可以根据客户要求改变包装方式。包装纸袋符合JG59－63《水泥包装用纸袋》标准。

High alumina cement packaging:

The cement bag should be moistureproof paper bag (four layers of ordinary wrapping paper, three layers of moistureproof paper), and the net weight of each bag should be 50 + 1 kilograms. We can also change the way of packing according to the requirements of the customer. Packing bags with paper bags for cement packing JG5963 "standard".

高铝水泥运输保管：

高铝水泥在运输和保管时，应防止受潮并须与其他品种的水泥分别贮运，不得混杂。

High alumina cement transportation and storage:

During transportation and storage, high alumina cement should be prevented from dampness and must be stored and shipped with other varieties of cement and must not be mixed.
