This study was conducted to evaluate the performance of rapid‐hardening roller‐compacted concrete containing styrene butadiene latex. This material has no slump and is compacted with a roller after being poured. Volume reduction is not a concern and the material has a high initial strength due to the high pressure applied. Latex improves the durability of ultra‐rapid‐hardening cement composites. This study evaluated the performance of an optimum mixture (L) and a mixture with no styrene butadiene latex (NL), which had almost the same workability as the optimum mixture. The L mixture exhibited better performance than the NL mixture in terms of bond strength and chloride ion permeability, as well as resistance to abrasion, repeated freezing and thawing, and scaling. © 2011 Wiley Periodicals, Inc.
