The method of high-performance polycarboxylic acids water reducing agent.
Background technology
The vast northern area weather in China is usually colder, and winter is up to the 4-6 months, is influenced on concrete engineering construction
It is very big.When the temperature increases, hydration is accelerated, and gain in strength is also very fast；And when temperature is reduced to 0 DEG C, it is present in coagulation
Some starts to freeze for water in soil, gradually becomes solid phase from liquid phase.At this moment participating in the water of cement aquation reduces, because
This, hydration slows down, and gain in strength is accordingly relatively slow.Temperature continues to decline, when the water being present in concrete becomes ice completely,
When namely becoming solid phase from liquid phase completely, cement aquation stops substantially, and intensity just no longer increases at this time, in order to ensure mixed
The quality and progress of solidifying soil construction, most economical effective method are to use antifreezing agent.Concrete antifreezer experienced villaumite type, chlorine
Salt hinders rust type, without the high alkaline of chlorine, no chlorine and low alkali type several stages.At present mixing plant using antifreezing component be nitrite, villaumite,
Urea, ammonium hydroxide etc..Not only alkali content is high in the diminishing component of these antifreezing agents, but also contains remaining formaldehyde, and environment-friendly type is poor,
In addition water-reducing rate is not also high, to the bad adaptability of cement, sand material, it is difficult to meet the requirement of current high performance concrete, it is antifreeze
Chloride ion content, sulphates content in component is very high, is unfavorable for improving the compactness and durability of concrete.Small molecule alcohol
It is a kind of relatively good antifreezing agent, but volume is higher, whole water-reducing agent higher price, produces in amino resin waste water containing big
Methanol and butanol are measured, usually all regards wastewater treatment, the waste of resource can be caused.
