MasterCast 750HS | Master Builders Solutions - North America
MasterCast 750HS admixture is a new generation plasticizer based on MasterGlenium polycarboxylate dispersant technology. This unique chemistry maximizes production efficiency through its cement dispersing and reactive lubricant mechanisms. Recommended uses: Concrete blocks. Dry-cast pipes. Paving stones. Hollow-core planks. Concrete roofing tiles.
MasterGlenium 3030 | Master Builders Solutions - North America
MasterGlenium 3030 admixture is very effective in producing concretes with different levels of workability including applications that require the use of self-consolidating concrete (SCC). MasterGlenium 3030 admixture meets ASTM C 494/C 494M requirements for Type A, water-reducing, and Type F, high-range water-reducing, admixtures.
Use of Water Reducers, Retarders, and Superplasticizer
ASTM C494 Type F and Type G, High Range Water Reducer (HRWR) and retarding admixtures are used to reduce the amount of water by 12% to 30% while maintaining a certain level of consistency and workability (typically from 75 mm to 200 mm) and to increase workability for reduction in w/cm ratio.

- What is water reducing admixture & superplasticizer?
- As one of the concrete admixtures, water reducing admixtures and superplasticizers are usually used to reduce the mixing water volume and improve the performance of the harden concrete while maintaining better workability of the fresh concrete.
- Can water reducing admixtures and superplasticizers be used in reinforced concrete?
- Water absorption, frost resistance and permeability resistance of the concrete are mainly reviewed to discuss this influence on the durability properties of the concrete. Then, some suggestions on the application of the water reducing admixtures and superplasticizers in reinforced concrete structures and projects are proposed.
- Can super plasticizer and retarder improve concrete workability?
- Alsadey (2013) investigated the effects of super plasticizer and retarder on the properties of concrete with a specific strength of 30 MPa. The results showed that the workability of concrete could be improved by adding a super plasticizer and a retarder. ... ...
- Which superplasticizer is best for precast concrete?
- PANTARHIT® F (FM) is a superplasticizer with accelerating properties suitable for producing ready-mix and precast concrete. PANTARHIT® FT100 (FM) is a high performance superplasticizer for producing high consistency concrete at low water/cement ratios in precast concrete plants.
- Can retardant admixtures be used on ready-mix concrete?
- The additional dose of retarding admixtures not only delayed the concrete setting but also improved the compressive strength of the concrete. This implies that the use of an additional dose of retardant admixtures specifically tailored for ready-mix concrete is an effective option to avoid the return of ready-mixed fresh concrete. ...
- Is superplasticizer better than retarder?
- From the results of the study presented superplasticizer and retarder. However, very high dosages of both admixtures tends to impair the cohesiveness of concrete. admixtures. However, effectiveness is higher for superplasticized concrete. have a better cohesiveness w ithout segregation. However, at very high dosages, cohesiveness reduces.
