Abstract

Process for repairing concrete compositions using cement mortar compositions which are capable of being pneumatically sprayed and which provide unexpectedly enhanced bonding capabilities and resistance to slump; said compositions comprising essentially a substantially non-air entraining portland cement, mineral aggregate, a styrene-butadiene copolymer latex present on a solids basis in an amount of from about 5 to about 25 percent by weight of cement, and water in an amount sufficient to provide a total water to cement ratio of from 0.22 to 0.26.
