15 Types of Admixtures Used in Concrete - The Constructor
Normal plasticizer reduces the water demand up to 10%, mid-range plasticizers reduce the water demand up to 15% while super plasticizers reduce the water demand up to 30%. Calcium, sodium and ammonium lignosulphonates are commonly used plasticizers.
Concrete Plasticizers, Cement & Plastic Fillers | USG
Cement & Plastic Fillers. Builders and project managers count on USG’s selection of concrete plasticizers and cement plasticizers to strengthen their structures. Our concrete plasticizer products reduce the water/cement ratio to achieve better results. View our plasticizer admixture for concrete and other offerings below.
Plasticizers For Concrete - Principle, Types & Advantages
The main advantages of using plasticizers are: Improves workability of concrete without the addition of extra water. Improves the strength of concrete without increasing the cement content. Increase the strength characteristics of the finished concrete foundation by twenty five percent.
Concrete GFRC Super Plasticizer Water Reducer, EvoTek 7015
Riteks EvoTek 7015 is an economical high-range water-reducing (HRWR) admixture based on polycarboxylate technology. EvoTek 7015 is especially suitable for ready mix, pre-cast, SCC and mix designs containing fly ash or pozzolonic material. EvoTek 7015 is ready-to-use and provides excellent early compressive strength, faster setting strengths
Concrete Water Reducer - Superplasticizers
7. Since the dosage of polycarboxylic acid superplasticizer is very small, the water reduction rate is high. The use of polycarboxylic acid superplasticizers to prepare various types of high-performance concretes above C45 can greatly reduce project costs and has significant technical and economic benefits; it is used to prepare concrete below C45, although the cost of polycarboxylic acid
- What are plasticizers for concrete?
- B. Plasticizers Plasticizers for concrete belong to the group of chemical impurities for construction, which reduce the amount of water required to obtain a certain consistency in concrete. In other words, the plasticizers mix and form the cement paste rapidly by coating the cement particles and making them repel each other.
- What makes a good plasticizer?
- A good plasticizer makes concrete or mortar flow in a way that is different from how an air-entraining agent does it. But some plasticizers also add air to the material, making it easier to work. A good plasticizer should add 1% to 2% of the air to concrete at most because adding air to concrete makes it less strong.
- Do Plasticizers improve the strength of concrete?
- The use of plasticizers generally improves the physical and structural properties of concrete, as well as increasing the profitability of the project; We have learned from experiences that the results have been positive with respect to the compressive strength of concrete.
- What are plasticizers & water reducers?
- Plasticizers and water reducers are chemical admixtures used to make concrete more workable. Unless the mixture is “starved” of water, increasing the w/c ratio reduces the concrete’s strength. An increase in durability is achieved by decreasing the water content (without “starving” the concrete).
- What are concrete superplasticizers & plasticizers?
- Our concrete superplasticizers and plasticizers for the production of quality concrete, ready-mixed/construction site concrete and precast parts made of reinforced and prestressed concrete. Quality and profitability with concrete superplasticizers and concrete plasticizers from Rhein-Chemotechnik GmbH.
- Why do we use plasticizer?
- The use of plasticizer is found to improve the desirable qualities of the plastic or green concrete. For making reinforced concrete or mass concrete of higher workability nowadays it has become a standard practice to use plasticizer or super plasticizer.
