Self compacting concrete (SCC) is a concrete mix that contains special admixtures to enhance the workability and rheological properties of the concrete. In addition, the admixtures help to reduce the water-to-cement ratio of the mixture.
Research has shown that the addition of superplasticizers has an effect on the strength of SCC. In the study, different dosages of PCE based superplasticizers were investigated. These dosages were added to a specific grade of cement. The results showed that the PCE-based superplasticizer has the ability to disperse the particles of cement efficiently and effectively. This admixture can meet the demanding requirements of the construction industry.
A number of different studies have been conducted on the use of SCC. Several of these studies have focused on the mechanical properties of the SCC. These tests include compressive and flexural strengths, viscosity, and L-box. Moreover, a method has been proposed to determine the optimal dosage of superplasticizer.
Comparative studies were conducted on nine concrete mixes. Specimen mix designs were identical to normal concrete NC specimen mix designs. However, each mix contained a different percentage of superplasticizer.
The results of the experiment indicate that the resistance of the beams made with SCC is comparable to that of the beams produced with conventional vibrated concrete. Furthermore, the experimental data showed that the bond strength between the SCC and VC elements is greater. The results of the bonding study were corroborated by the results of the V-Funnel and yield stress test.
