Description
Technical field
The present invention relates to a kind of cement additire technical field, more particularly to a kind of grinding aid for preventing high-mark cement from ftractureing
Agent.
Background technology
At present, the external low-grade cement to label P.C32.5 has been no longer used to Structural Engineering, is used in practice in a large number
It is the high-mark cement of P.O42.5 and P.II52.5 and the above.With regard to cement downstream product concrete product, for manufacture of cement
For enterprise and unit in charge of construction, carry out producing ready-mixed concrete in control cost using low-grade cement, pour, conserve etc. and applying
All it is easier in terms of work, but is to do harm rather than good in terms of the durability of raising building and energy-saving and emission-reduction；If using high
Grade cement can increase the life-span of building, while reduce repeatedly keeping in repair the wasting of resources for causing, greatly save energy consumption, but high standard
The early hydration heat increase of number cement, hydration rate are accelerated, and setting time is short, increases the deformation of cement early-age shrinkage, easily causes out
Split, disadvantages mentioned above is never effectively solved, it is that high-mark cement fineness is thin, specific surface area is big to trace it to its cause,
Excessive chemical key is quickly formed between grain, Van der Waals force is produced；The fluidity of cement is reduced, and is to ensure cement fluidity, needs to increase
Add water gray scale.High-mark cement is used in concrete, and concrete can be caused to protect plasticity, durability to be reduced, hold after concrete formation
The problems such as compatibility poor of easy to crack, later strength variation, concrete and additive.Therefore, research and development are found and can be solved
The additive product for preventing high-mark cement cracking is imperative.
