Powder for Mortar Polycarboxylate-Based Ether Superplasticizer
Polycarboxylate superplasticizer is a an environment friendly high range water reducing agent for all kinds of concrete. It has enhanced pumping performance and workability by outstanding slump retaining and higher water reducing ability. Thus it can be widely used in ready-mix concrete, precast concrete, pumping concrete, self-compacting concrete. It has specially excellent poerformance when used in high strength and durability concrete.
Our liquid polycarboxylate is easy to use and adjustable, and has good compatibility with all portland cement. Advantages in technology and performance as following:(1) low dosage, high rate of water reducing;
(2) keep concrete good slumption retention;
(3) good compatibility with cement;
(4) small shrinkage of concrete to keep the stability of volume and durability;
(5) environmental in production and usage. Base on above advantages, PCE superplasticizer attract the attention from engineering field and has been widely used in some important projects. Predictably, base on above advantages, PCE superplasticizer will be the main trend in the market.
Due to most of PCE superplasticizer is liquid and procedure of PCE powder is complex and
dangerous, PCE superplasticizer is mostly sold in liquid in market. Recently, with the
technology and procedure improved, PCE powder is common in market. the powder will be more
convenient for client in transport and use. So the powder is becoming the trend of this product. Main Performance: Visual appearance: white powder| Density | Solid Content | PH value | Chloridion | Total Alkali |

When dosage is from 0.12% to 0.22%, the cement paste fluidity grows obviously.
There is no loss of fluidity within 1 hour in cement paste.
The fluidity of PCE powder is 2 times of other superplasticizer in market.
Motar Performance
It is homologous between water-reducing rate of motar and fluidity of cement paste.The more fluidity of cement paste, the more water-reducing rate of motar.
Water-reducing rate increases fast and high when the dosage increase. When the dosage is same,the water-reducing rate of PCE powder is 35% higher than that of other superplasticizer in market.
Due to the influence from the admixture and sand coarse aggregate, Water-reducing rate in concrete is different from that of motar.When the the admixture and sand coarse aggregate are in favour of the concrete flow, the water-reducing rate of concrete is higher than that of motar.
It has antifreezing performance when temperature is above -5ºC. So it can be used in antifreezing concrete. Concrete PerformanceStrength and Mix Proportion of Concrete(kg/m3)| | water | cement | sand | aggregate |

3,Recommed Dosage:
The recommend dosage of superplasticizer for concrete: 0.1-0.25% base on cement quantity.Performance:
1. High water reducing rate: Water reducing rate more than 25%.
2. Molecule controllability: Water reducing rate, slump-loss retarding and air entraining can be adjusted by changing the molecular weight of the main chain, the length and carboxylic group of secondary chain.
3. Excellent slump retaining: Offer low slump without affecting concrete setting time.
4. Outstanding dispersity: Greatly improve the concrete flow property, suitable for pumping and self compacting concrete.
5. High strength growth rate and durability: Improve concrete strength of every ages, low shrinkage resulting in higher concrete durability.
6. Great Compatibility: Suitable for for all mixing materials, such as portland cement, ordinary portland cement, slag portland, fly ash cement and volcanic ash cement.Application:1. High water reduction: Excellent dispersion can provide a strong water reduction effect,the water reduction rate of concrete is more than 40%, it provide a guarantee to improve the performance and strength of concrete, saving cement.
2. Easying to control production: Controling water reduction ratio, plasticity and air entraining by adjusting molecular weight of main chain, length and density of side chain, type of side chain group.
3. High slump retention ability: Excellent slump retention ability, especially has good performance in the low slump maintain, to ensure the performance of concrete, without affecting the normal condensation of concrete.
4. Good adhesion: Making concrete have excellent workability, Non-layer, without segregation and bleeding.
5. Ecellent workability: High fluidity, easily deposing and compacting, to make concrete reducing viscosity, without bleeding and segregation, easily pumping.
