Its form is divided into polycarboxylate concrete water and powder.
Water formulations contain 20%, 40% (also known as alcohol) and 60% solids, while powders typically contain 98% solids, depending on the reducing agent’s ability to reduce and improve water.
It is divided into common dehydrating agents.
(referred to as plasticizers Water reduction ratio greater than 8% based on lignosulfonate) High efficiency polycarboxylate concrete
(also known as superplasticizer) Plasticizer Water reducing content 14% or more nephtha Fat, base melamine, sulfate, fatty, etc.
And high performance water reducing agent.
(including aqueous reducing agents containing 25% or more aqueous reducing agents with polycarboxylic acid), initial strength, standard class and slow class.
Depending on the composite material, it is divided into:
- polycyclic aromatic salts;
- soluble sulfonate resin;
Naphthalene plasticizers, aliphatic plasticizers, amine plasticizers, polycarboxylate plasticizers, etc.
Lignosulfonate superplasticizer, naphthalene superplasticizer, melamine superplasticizer, sulfate superplasticizer, acidic superplasticizer, wetting agent, Polycarboxylate superplasticizer.
Superplasticizers have a high diffusive effect on the cement and can increase the fluidity of the cement mixture and cause the polycarboxylate concrete to fall.
While reducing water consumption and improving the durability of concrete. and can cause excessive bleeding.
In principle, superplasticizers do not change the service life of concrete. When the dosage is high (overdose), there is a slight delay in the setting process.
But it will not slow down the initial strength of the hardened concrete.
It can polycarboxylate concrete consumption and increase the strength of concrete for all ages.
By maintaining constant resistance It can contain more than 10% cement, very low chloride ion content and does not corrode steel bars.
It can improve the waterproofing, defrosting and corrosion properties of concrete. and improve the durability of concrete.
