Figure 1 Influence of the addition of superplasticizers on the early strength of concrete with cement content of 370 kg/m 3 and cast in room temperature (Neville, 1995). Loss of Workability Figure 2 Loss of Slump with time of Concrete: (A) w/cm 0.58 and no admixture; (B) w/cm 0.47 and superplasticizers (Neville, 1995).
Concrete Admixture is defined as a material other than water, aggregates and hydraulic cement and additives like Pozzolana or slag and fiber reinforcement, used as on ingredient of concrete or mortar and added to the batch immediately before or during its mixing to modify one or more of the properties of concrete in the plastic or hardened state.
The other major application is the production of high-strength concrete at w/c's ranging from 0.3 to 0.4. The ability of superplasticizers to increase the slump of concrete depends on such factors as the type, dosage, and time of addition of superplasticizer; w/c; and the nature or amount of cement.
CBD-203. Superplasticizers in Concrete. Originally published February 1979. V.S. Ramachandran. A superplasticizer is one of a class of admixtures called water-reducers that are used to lower the mix water requirement of concrete.
The saturation dosages obtained can be ranked as PCE < SMF < SNF < LS. The effect of C 3 A, C 3 A/SO 3 and alkali contents on slump retention of concrete varied with the type of superplasticizer used.
