LA Repair Concrete is a blend of special Portland cements, ground granulated blast furnace slag plus high quality continuously graded non ASR reactive aggregates. The product, when mixed with water, produces a homogenous concrete which will not segregate or bleed and has a dual shrinkage compensating system giving volume stability in both the plastic and hardened states. The mix has high flow characteristics and will not rapidly stiffen.
LA Repair Concrete may be used for all concrete repairs wherever a flowing concrete is required. The product is easily mixed and placed under gravity or by pumping. The placed material is self compacting and will displace air from the repair area ensuring a strong bond between the placed material and the repair substrate.
The use of the Portland blast furnace type of cement gives a mix design with less than 3kg of equivalent sodium oxide per m3 thus minimising the risk of alkali aggregate reaction even in the parent concrete. In addition, the midrange resistivity enables cathodic protection to be undertaken in conjunction with LA Repair Concrete.
