'Jinning Rams' P¢ò52.5 and P¢ò42.5R Portland Cement
It features high early strength, fast coagulation
and hardening, outstanding resistance to freeze and abrasion,etc.
It can be widely used to prepare high-intensity concrete, reinforced
concrete, prestressed concrete, and special concrete that can be
constructed under low temperature. It is especially applicable in
the construction of industrial factory buildings, high-rises, bridges,
roads, airports, and so on.

'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.
