New Trends in the Development of Chemical Admixtures in Japan
an air entraining high-range water reducing agent, a new accelerator for shotcrete, and a viscosity agent and its novel application as a retarder in a recycling system for sludge water in ready mixed concrete plants. 2. History of chemical admixture use in Japan Figure 1 shows the history of chemical admixture use in Japan.
Concrete Admixtures | Cement Admixtures | Fosroc | Fosroc
Fosroc is a leader in concrete admixtures, with tailor-made formulations carefully designed for specific customer use. Our renowned Aura, Structuro and Conplast series deliver high quality, exceptional performance and cost-effective solutions for concrete producers all over the world. Fosroc manufactures and supplies: Superplasticizers Plasticizers
Chemical Admixtures - Cement
Superplasticizers, also known as plasticizers or high-range water reducers (HRWR), reduce water content by 12 to 30 percent and can be added to concrete with a low-to-normal slump and water-cement ratio to make high-slump flowing concrete.
Admixtures | Super Plasticizers - RussTech
RussTech carries a full line of super plasticizing concrete admixtures including ones that contain the new polycarboxylate technology. These high range water reducers have been specifically designed to increase strength while maintaining extended flowability at lower water to cementitious ratios in the concrete mix. SuperFlo 443. SuperFlo 2000RM.
Plasticizers the admixture for the concrete block industry
We are pioneers in the development of plasticizers for earth-moist concrete for the production of high-quality directly demolded concrete block products in fully automatic production installations using the vibro-compaction and pressing process. we would be happy to help you select the right product for your individual application.

- Are comb-type superplasticizers used in Japan?
- “Molecular structure and dispersion-adsorption mechanisms of comb-type superplasticizers used in Japan.” J. Advanced Concrete Tech., 1, 16-25. Sakata, N., Yanai, S., Yokozeki, K. and Maruyama, K. (2003). “Study on new viscosity agent for combination use type of self-compacting concrete.” J. Advanced Concrete Tech., 26-36.
- What Admixtures are used in concrete in Japan?
- Chemical admixtures such as air entraining (and high-range) water reducing agents are used in most concretes in Japan. Moreover, many types of admixtures that provide the performance demanded by new con- struction technologies are in use.
- What is PC based superplasticizer?
- With PC-based superplas- ticizers, many types of polymers can be synthesized and new types of PC-based superplasticizers can be supplied by reformulations of the polymers. On the other hand, the use of waste is also active in Japan in the manufacturing of ordinary Portland cement.
- What is a low stickiness type PC based superplasticizer?
- A low-stickiness type PC-based superplasticizer has been developed based on the conventional PC-based superplasticizer. The flowing speed of concrete with low stickiness type PC-based superplasticizer is faster than that with the conventional PC-based superplasticizer.
- Which plasticizers are flame resistant?
- Flame-retardant plasticizers provide fire resistance to polymers such as PVC. A representative example is organophosphate. SANSO CIZER TCP (Tricresyl phosphate) is an organophosphate with excellent flame and weather resistance as well as electric insulation properties.
- What are antistatic plasticizers?
- Antistatic plasticizers provide polymers such as PVC with antistatic properties. SANSO CIZER C-1000 and C-1100 are antistatic plasticizers developed for flexible PVC, urethane and nitrile rubber. They are perfect for products requiring an antistatic function such as flooring, partition curtains and footwear.
