A. Portland cement 1. Type: Common portland cement, slag portland cement, portland-pozzolan cement, flyash portland cement. Grade: 425# -
B. Special cement 1. High quality and low-heat portland cement for large scale engineering Well-known for its advantages of high flowability, high strength, high durability, extremely low-heat of hydration and superb ability in resisting the corrosion of sulphuric acid. Its functions are much better than common low-heat slag cement. It is suitable for large scale engineerings, large volumn concrete processing as ideal gelled material to make high grade concrete. 2. Early strength fast hardening specific oil well cement Compared with common oil well cement, the product has advantages of early strength, fast hardening and permeability resistance and because of its micro-dilatability, it can closely cement the stratum and sleeve pipe to avoid moves between layers and oozing outside pipe. It is suitable to adjust and fix wells, especially for knotty well and suitable to well-fixing engineering in drilling industry such as small diameter well fixing and sleeve pipe fixing in various layers. 3. Large dam cement Characterized by relatively low-heat of hydration, uniform and stable quality. It is mainly used in building large scale irrigation works like diversion dam, hydroelectric station and large column concrete engineering that require the low-heat of hydration of cement. 4. Portland cement for road building Good properties include early strength, high bending strength, low bending modulus of elasticity, wear resistance, low contracting, freeze thaw resistance, resisting corrosion of the sulphuric acid and satisfy the technical requirements of road engineering of different grades. It can be widely used in various kinds of concrete road engineering and other construction engineering. 5. Other specific cement
