  • Can superplasticizers improve cement flowability?
  • Adding superplasticizers to cement provides remarkable improvement in cement and concrete flowability. Such improvement in flowability is, however, not compromised by a reduction in the compressive strength (which is a function of the water-to-cement ratio) of the resultant concrete.
  • What class of concrete is a superplasticizer?
  • Upon the set compressive strengths the monitored concretes were classified to particular strength class of concrete. In particular, the concretes P_1 and 2 (plasticizer) met C 30/37 and concretes SP_3 a 4 (superplasticizer) were filed in the strength class C 35/45.
  • Can superplasticizers improve cement paste & water-to-cement ratio?
  • Finally, future perspectives of the impact of using superplasticizers on cement paste, water-to-cement ratio, and enhancing the overall performance of concrete have been outlined. Water-reducing chemicals are additives used in concrete mixtures to reduce the amount of water required without compromising its workability.
  • Why are superplasticizers important in the construction industry?
  • The advancement of superplasticizers is considered a significant innovation in the construction sector, which has facilitated the creation of high-quality concrete. The construction industry has a pressing need for the development of high-performance concrete.
  • What are the electrokinetics and rheology of concrete mixtures containing different superplasticizers?
  • Electrokinetics, rheology, and flow properties of cements and concrete mixtures containing different superplasticizers are critically evaluated, and various parameters such as zeta potential, adsorption, flowability, hydration, and non-Newtonian behavior are discussed.
  • Is superplasticizer a good choice for hardened concrete?
  • The experiment program included tests on workability, slump test, and flow table. 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.
