Abstract
The use of Superabsorbent Polymers (SAP) to promote internal curing of concrete is one of the techniques used to mitigate its autogenous shrinkage. SAP absorbs water from the fresh mixture and releases it in a later stage when the relative humidity of the concrete pore system decreases due to the cement hydration. Several studies indicate that besides leading to a substantial reduction in autogenous shrinkage the addition of dry SAP to concrete also affect other properties of concrete such as workability, mechanical behavior and durability. This chapter gives an overview of the effect of SAP on the workability of High Performance Concrete (HPC), Ultra High Performance Concrete (UHPC) and OPC mortars. Considering that at present only few results are available in the literature regarding the influence of SAP on the workability of concrete, serious research efforts will be necessary to fully understand the rheological behaviour of concrete containing SAP.
