Although the problem of water penetration occurs only after the curing process of the concrete, it is very important that during the curing process enough water is supplied to the cement for its hardening process. Otherwise, a phenomenon called ?Die of thirst" will occur to our concrete. This process is illustrated in figure 6.
For the curing process of concrete a well defined amount of water is needed to allow the cement to react with the soil.
If this amount of water will now be decimated, let us say through evaporation caused by heat, the cement will not be able to react properly with the soil.
Therefore, big clusters in the concrete will be formed, which have no reasonable strength. The effect hereof is, that within the concrete a structural weakness is performed, which is causing cracks or in a severe form, after load, potholes.
To avoid this structural weakness should be the task of every concrete additive for road construction.
Fig. 6
Renolith's WSS is able to supply water when and where it is needed.
If now necessary water for the binding process is lost because of evaporation or something else, the missing water will be supplied complete from Renolith.
Therefore, the binding process of the cement can be completed properly without having any clusters, which have no reasonable strength. That means, no cracks and of course no potholes will occur. The remaining water, stored in Renolith, will control the humidity of the concrete and keep it at its optimum. Resulting therefrom, the shrinkage of the Renolith base is reduced to a minimum.
Fig. 7
To draw the conclusion, you can say that Renolith based roads are more resistant against cracks than normal roads and have a lower shrinkage during curing time. Therefore, our roads have a longer durability and again less need of maintenance
