'Zhongshan' G-Class Anti-Sulphate Oil Well Cement

Features: Thanks to stable proportion of grouting cement, good flowing property, proper thickening time, and relatively high strength, it is a sound well cementing material( Suitable well depth: 2440m or below). If used together with accelerator or retarder, it can be applied for deeper well cementation. With exceptional corrosion resistance to sulphate, it can also be used in sulphate-attack-proof projects. Moreover, it enjoys very good adaptability to cement additives, such as retarder,flow improver, filtrate reducer, weight additive, lightening additive,etc.

¡®Zhongshan¡¯ Clinker Micropowder

Features: Zhongshan clinker micro-powder, with its leading model S95, is produced according to GB/T18046-2000 Standard for preparing ready mixed concrete in place of equivalent cement in the proportion of 30-50%. What¡¯s more, it can improve the performance of concrete, lowering weepage and hydration heat, enhancing fluidity and plasticity, thus highly efficient in preventing the crack and deformation owing to internal temperature rise of a large volume of concrete. And the hard concrete with clinker micro-powder in, has excellent performance in resistance to sulfate, chloride and alkali, with long-term strength and durability greatly enhanced. So our clinker micro-powder is favorably chosen to the application in big projects (esp. suitable for underground and underwater projects) and big manufacturers of concrete.

¡®Zhongshan¡¯ 42.5 and 32.5 Portland Cements

Features: The Zhongshan 42.5 and 32.5 Portland Cements are excellent featuring stable quality and high strength, thanks to which the concrete prepared with either has good wearing resistance, low drying shrinkage, high compression strength and folding strength. They can be used in the industrial/civil architectural engineering. Zhongshan 42.5 is more applicable to important construction works than Zhongshan 32.5.
