SIFCON with Latex Modified Cement Slurry Used for a Thin Overlay of a Bridge Deck

In the paper, the use of latex modified cement slurry (LMCS) for the preparation of SIFCON (Slurry-Infiltrated Fibre Concrete) is discussed. An example of use of SIFCON with LMCS for a thin overlay which acted as a waterproofing-abrasive bridge deck layer is presented. A research was performed in order to point out the positive and negative parameters of this type of application, which have an influence on the latter use and durability. Since SIFCON has so many favourable properties, there is no doubt that it is suitable for the construction of bridge deck overlays. Nevertheless there is still an open question about ensuring the satisfactory installation of SIFCON on site. For this reason, high-performance fibre reinforced concrete (HP FRC) of similar properties to those of SIFCON was developed. This HP FRC is prepared at the concrete production plant so that the total volume of the fibres is ready-mixed in the plant. (A)
