The Effect of Various Superplasticizers on Ultra High
Four different types of superplasticizers were used; two different PCE based superplasticizers from a leading manufacturer (PCE Name Brand 1, PCE Name Brand 2), one PNS superplasticizer, and one PCE superplasticizer (PCE Local Provider), both of which were provided by a local chemical provider.
Synthesis and Properties of a Polycarboxylate
Polycarboxylate superplasticizers (PCEs) emerged as one of the most important superplasticizers for concrete due to their superior performance. (1,2) Compared to other products like polycondensates, they fluidize cement even at low water to cement ratios, require relatively low dosages, and exhibit a long slump retention capability. (35) The
A New High Charge Density Superplasticizer Regulates the
The superplasticizer can improve rheological behavior and facilitate transportation operations. Superplasticizer was a modified polycarboxylic acid superplasticizer prepared by free radical polymerization of acrylic acid, quaternary ammonium salt, and isopentenyl polyoxyethylene ether.
Effect of dosage of superplasticizer on earth concrete
The mix with 2 % superplasticizer was capable of achieving the maximum density at a water cement ratio lower than that of matrix with 1 % superplasticizer dosage. Mixes with 0 % and 3 % superplasticizer dosages also exhibited similar maximum densities, but, the attained density is lower than that of 2 % and 3 % superplasticizer dosage.
ADVA 198 Data Sheet | Resource | GCP Applied Technologies
Product Description ADVA 198 superplasticizer is a polycarboxlate-based high-range water-reducing admixture specifically formulated to meet the needs of the concrete industry. It is a low viscosity liquid, which has been formulated by the manufacturer for use as received.
- What is PCE superplasticizer?
- PCE superplasticizer is a high-performance water reducing agent that integrates many functions such as high water reduction, high collapse retention, reinforcement, shrinkage, and environmental protection. It is also an ideal admixture for preparing high-strength and high-performance concrete.
- What is polycarboxylate superplasticizer?
- The Polycarboxylate Superplasticizer can reduce the amount of cement, and the water reducing rate can reach more than 30%. This product can mainly improve the strength of mortar, which is defined as water reduction and reinforcement without affecting the workability of concrete.
- What is a polycarboxylate ether superplasticizer?
- The polycarboxylate ether superplasticizer is an additive commonly used in concrete engineering and has a wide range of applications. The PCE based admixture can significantly reduce the amount of cement and improve the fluidity and pumpability of concrete while ensuring the strength and durability of concrete.
- Can polycarboxylate based superplasticizer improve the crack resistance of concrete?
- The polycarboxylate based superplasticizer can improve the crack resistance of concrete. After adding an appropriate amount of water reducing agent in concrete, the internal structure of the concrete can be improved and the contraction and cracking of concrete can be reduced.
- Is polycarboxylate superplasticizer soluble in water?
- The product is easily soluble in water, and has a good dispersing effect on many powder materials such as cement. The Polycarboxylate Superplasticizer can reduce the amount of cement, and the water reducing rate can reach more than 30%.
- How to store PCE polycarboxylate superplasticizer?
- The PCE polycarboxylate superplasticizer should be stored in a cool, dry and well-ventilated place, avoiding direct sunlight and rain. At the same time, it should be kept away from fire and heat sources to prevent fire or explosion accidents. Water seepage problem.
