The water cement ratio was maintained as 0.55, 0.40, to study the effect of these super plasticizer on various properties of concrete. The dosages of super plasticizer were adopted as 0.25% by
CHRYSO® New Generation Super Plasticizer enables the concrete manufacturer to produce high performance, flowable concrete varrious grades with high fines content. It also minimizes the risk of excess retardation though retains the Flow / Workability for longer time period, often to the tunes of 3-5 hours.
- What is the effect of super plasticizer on concrete?
- The effect of the super plasticizer is the increase of the workability of the concrete in case of use of low water/cement ratios. Additionally the porosity of the concrete is reduced.
- 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.
- Is re-tempering with superplasticizer harmful?
- The good news are that at the end, the final strength usually will not be affected when retempering with superplasticizer, because if you do so with water, the strength will be affected dramatically. Re-tempering with chemical admixture (need proper mixing after re-tempering, at east 70 revolutions in 2/3 minutes in transit trucks) is not harmful.
- Do superplasticizers increase zeta potential of cement pastes?
- SNF based superplasticisers resulted in the most effective increase of the zeta potential of cement pastes both in the case of OPC and PPC. Tamrakar and Mishra (2013), This paper was conducted to study the effect of superplasticizer on properties of concrete with characteristic strength of 20 and 40 N/mm².
- What is the difference between superplasticizers and set retards?
- Superplasticizers disperses cement provides plastics with higher initial strength than free concrete with the same W/C ratio. Set retards are adductors that cause delays in the setting time of wet concrete mixes.
- What is a superplasticizer?
- Superplasticizer is chemical admixtures added to the concrete to improve their flowing ability also known as high range water reducers.
