Influence of the dosage of super plasticizer on properties
In the given study, the influence of the polycarboxylates based super plasticizer (SP) (high-range water reducer) at different dosages to the properties of HPC was investigated. SP in concrete mixtures was added with ratios of 1.0%, 1.5%, and 2.5% by weight of cement. The samples characteristics of produced concrete were compared with each other.
Effect of Superplasticizers to Enhance the Properties
This study aimed to study the effects of asuperplasticizing admixture, namely, Sikament-NN superplasticizer, on concrete properties, such as workability and compressive strength. Experiments were...
Effect of Super-plasticizer Dosages on Fresh State Properties
The early age properties of concrete control the hardened properties of concrete such as creep, durability and its performance. Admixtures are added to the concrete to achieve a desired change in its properties. This study focuses the effects of super-plasticizer (Duraplast SP-400) dosages on the early age properties of concrete.
Effect of superplasticizers on the rheological properties
This paper explores the influence of superplasticizer dosage, superplasticizer family and mineral admixture dosage on the rheological behavior of cement paste. For this purpose cement pastes were prepared at a water cement ratio of 0.37 using OPC and different percentage of fly ash (15, 25, 35) and different dosages of superplasticizer (one
- Does superplasticizer affect compressive strength of concrete?
- The results also appeared that compressive strength of SCC slightly decreased compared with that under 15 min mixing time. The increase in dosage of superplasticizer has mitigated the negative effect for long mixing periods on the properties of concrete. 1.
- What is the dosage of superplasticizer?
- For general usage, dosage of superplasticizer is between 1- 3 l/m3. However, the dosage can be increased to as high as 5- 20 l/m3. Since concentration of superplasticizer is different, any comparison of performance should be made on the basis of the amount of solids, and not on the total mass.
- What are the effects of superplasticizer?
- Effects of superplasticizer are obvious, i.e. to produce concrete with a very high workability or concrete with a very high strength. Mechanism of superplasticizer is through giving the cement particles highly negative charge so that they repel each other due to the same electrostatic charge.
- How does superplasticizer dosage affect matrix workability?
- As the superplasticizer dosage is increased the workability of the matrix increases. The matrix with no super plasticizer has the least workability and the one with 3 % superplasticizer has the most workability. Also, the rate of gain in workability is found to increases with increase in superplasticizer dosage.
- How much ml of superplasticizer admixture should be used?
- 1000 and 1200 ml/100kg of ce ment. At maximu m dosa ge the slump value in mm also maximum and it shows higher value at sp ecimen MS 5. When observation is done on the content of superplasticizer, increase in dosage concrete to the site. However, over dosage of this admixture will lead to high slump loss, which will not give
- Does a 3 % super plasticizer dosage increase compressive strength?
- Similar results have been observed for all super plasticizer dosage. However, for 3 % super plasticizer dosage, the critical water cement ratio to attain the maximum compressive strength was found to be at a water content lower than that required for making a workable mix.
