Influennce of ingredient of super plasticizers on concrete
The effects of super plasticizer on fresh and hardened concrete were investigated. The experiment program included test on workability, slump loss and compressive strength. In this experimental...
Influence of Polymer Superplasticizers on Various Types
The article presents the results of a study of various types of carbon nanomaterials introduced into polymer superplasticizers and tests of the obtained additives in concrete. It has been established experimentally that during the growth of crystals they partially penetrate into each other and form a spatial network that pierces the entire cement stone and connects it into a single whole, due

The Effect of Various Superplasticizers on Ultra High
Ultra-High Strength Concrete (UHSC) is a high-strength and highly ductile material formulated to provide compressive strengths exceeding 130 MPa. UHSC materials typically have a very low water-to-cementitious ratio (w/cm), which requires the use of superplasticizers, also known as High Range Water Reducing Admixtures (HRWRA), to disperse the
Use of Water Reducers, Retarders, and Superplasticizers.
The use of WRA is defined as Type A in ASTM C 494. WRA affects mainly the fresh properties of concrete by reducing the amount of water used by 5% to 12% while maintaining a certain level of consistency, measured by the slump as prescribed in ASTM C 143-90. The use of WRA may accelerate or retard the initial setting time of concrete.
- What is the influence of superplasticizer?
- The influence o f a superplasticizer by the name of is added . Since workability of low water/cement ratio concrete. In additio n, they claimed that superplasticizer can requirement and slump loss. superplas ticized concrete. When super plasticiz er is adde d to concrete structures .
- Does superplasticizer admixture improve concrete performance?
- This paper outlines an experimental study that measures the effects of superplasticizer admixture on proprieties of concrete. However, Superplasticizers are the most important admixtures enhancing concrete performance.
- Does Fra affect concrete mixes containing superplasticizers?
- Whilst the higher specific surface of FRA may negatively influence mixes containing superplasticizers because the polymeric chains have a larger contact area, the steric effects produced in concrete made with polycarboxylic superplasticizers may mitigate the negative effect of incorporating FRA. Fig. 9.
- Does super plasticizer affect the slump value developed for concrete?
- (0.2,0.4,0.6,0.8,1.0,1.2)% with cement content .The influence of variation in super plasticizer on the slump value developed for concrete is evaluated and also super plasticizer addition for concrete are examined by monitoring compressive strength as a function of curing period.
- Which type of super plasticizer is used in the project work?
- In the present project work grade of concrete M30 is used for the study and four type of super plasticizers ( Chloride free sulphonated naphthalene polymer, Naphthalene Formaldehyde condensate, Sulphonated Naphthalene formaldehyde condensates, Modified Naphthalene formaldehyde condensates ) are used for present study.
- What are superplasticizers and how do they work?
- Superplasticizers are powerful water reducers that enable an increase in the ultimate stress of concrete by decreasing the w/c ratio, a decrease in the cement content while maintaining the same range of strength or workability, an increase in concrete compacity, and other effects [30].
