Internal curing of HPC with hydrogel

Popis výsledku v původním jazyce

High performance concrete (HPC) is concrete with a very high cement content and very low cement/water ratio and this leads to better properties of concrete. These concretes have a problem with traditional methods of curing because of very dense cement matrix. Water from outside cannot reach the interior of the concrete to achieve hydration and it may not have enough curing water for cement hydration. In this paper is discussed effect of internal curing of HPC. The objective of internal curing is to create water storage inside concrete. This should be achieved with hydrogel which was selected to examine influence on internal curing. Hydrogel has a high water-absorption capacity about 300% so it should create a sufficient supply of water in internal reservoir. The prediction is that the hydrogel will release water after the concrete get hardened and provide water to another cement hydration. This should lead to the concretes with better properties.
