Aluminate cement, aluminous cement, refractories, Yangquan Zhengyuan manufacturers supply

Introduction aluminate cement CA-50 I. Overview Cement, previously known as high-alumina cement, alumina cement. Currently, according to the standard GB201-2000, where the calcium aluminate-based, aluminum content of 50% -60% of the clinker grinding of hydraulic material, said cement, depending on the content can be divided into: CA-50, CA-60, CA-70, CA-80 several levels. Second, the performance and the use of CA-50 aluminum main mineral components of acid cement aluminum acid-calcium (CA), aluminum acid-calcium (CA2), seven aluminate twelve calcium (C12A7), calcium aluminum melilite (C2AS). Wherein CA mineral water speed, setting normal, with fast hard, early strength characteristics. CA and CA2 relatively slow rate of hydration, but later the strength of big growth, this mud-day compressive strength of antibiotics can reach about 90% of maximum strength. Our quality management therefore to day, three days a compressive and flexural strength to divide cement grade. Cement has a high temperature resistance, high temperature can maintain high strength, and can CA2 content with increasing its temperature performance also improved, therefore, it is suitable for use in the preparation of various refractory concrete binding agent. According to the use of different grade (or high alumina clay) refractory aggregate, may be formulated ambassador temperature in 1400. C below the fire-resistant concrete. Third, the product quality Our product selection of quality raw materials, in strict accordance with the ISO9001 quality management system, produced according to national standard GB201-2000 aluminate cement provisions. Aluminate cement CA-50 is divided into CA-50-X5, CA-50-X6, CA-50-X7, CA-50-X9 four models.

Fourth, the test methods to test in accordance with test methods specified in the national standard GB201-2000 foreign users can be equivalent to the use of foreign advanced standards BS915.2 comparison testing. Fifth, the packaging with standard three composite cement bags, 50 kg per bag, you can also consult the packaging according to the user's needs. VI Notes in the construction process, Portland cement, lime, calcium hydroxide can precipitate gelling material shall not be mixed with aluminate cement. It can not be used for engineering alkaline solution. Starting immediately from hardening water conservation. Aluminate cement hydration heat set in the early release, it is generally not mass concrete pouring. When used in reinforced concrete, reinforced protective layer thickness of not less than 30mm. Shall not be in contact with the uncured Portland cement concrete use, it can be used in contact with the silicate concrete with a strength of the release, but not long Jiecha place in a wet state. Prevent moisture caking, kept for three months. About us Yangquan Zhengyuan Refractories Co., Ltd. located in the famous township refractory materials - Yangquan, Shanxi.
