Influence of superplasticizer on strength of concrete - ResearchGate
However, compressive strength is improved by dosage 1.0% of SP after 28 days curing is 55 N/mm2, which is higher than that of control concrete, the optimum amount of admixture must be 1%. Over...
Influence of Super plasticizer on the Compressive Strength and Setting
the workability of M15 grade concrete, determine the effect of super plasticizer on the setting time of concrete, determine the effect of super plasticizer on the compressive strength of M15 grade concrete, determine the of optimum dosage for each super plasticizer in terms of workability and compressive strength of M15 grade concrete. 2.
Effect of Added Plasticizers on the Strength Metrics
Polycarboxylate additives change the strength of the samples as follows. The superplasticizer Melflux 5581 F in the amount 0.15% (by weight) increases strength in compression by 76% and in the amount 0.2% (by weight) the value increases by a factor of 2 and is equal to 34.8 MPa.
Effect of Superplasticizer Dosage on Workability and Strength
As the amount of superplasticizer is raised, it acts as a water reducer, reducing the amount of water available for the concrete mix. The correct amount of superplasticizer resulted in a loss of...
Effect of Super-plasticizer Dosages on Fresh State
With the increase in SP dosage, concrete compressive strength at early age reduced however its strength at 28 days increased by adding SP dosage up-to 2%. Workability and setting time were...
- Does superplasticizer increase compressive strength?
- Addition of super plasticizer allows for better flowing concrete, which allows for a system with lower number of voids. As a result, the maximum attainable compressive strength increases with increase in superplasticizer dosage. As super plasticizer dosages increase, the water requirement to attain maximum compressive strength reduces.
- 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.
- Is superplasticizer based concrete good for compressive strength test?
- For hardened concrete’s compressive strength test, we compared the properties of superplasticizer-based concrete with those of concrete without superplasticizer. The superplasticizer led to a significant water reduction but maintained workability. Content may be subject to copyright.
- Do superplasticizers improve the workability of concrete?
- This signifies that the superplasticizers used in this study has not only improved the workability of concrete but has also had a positive impact on the concrete strength in construction industry as a whole, thus more suitable compared to the past studies in consideration. ...
- Does asuperplasticizing admixture affect concrete 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 performed on different concrete mixes with water–cement ratios of 0.50, 0.55, and 0.60.
- Does naphthalene based super plasticizer improve the strength of earth concrete?
- By the incorporation of Ceraplast 300, a naphthalene-based super plasticizer, the density, workability and the compressive strength of earth concrete have been enhanced. The paper considers the effect of dosage of super plasticizer on the workability, density and strength characteristics of earth concrete.
