A concrete additive, which provides superior pump component protection, reduction of corrosion including wear and damage on pump components, and increased lifespan of the components in a concrete pump system. As concrete slurry mixes in the pump barrel of a ready mix cement truck, the concrete slurry blends directly with the pump additive and converges with the concrete pump components as the concrete blend mixes. This direct contact allows the pump additive to lubricate the component parts, which provides a corrosion inhibitor that protects the component parts from the harsh side effects of the aggregate rubbing against the liners, pistons and pump component parts thereby significantly extending the life of the component parts of the concrete pumping system. The cement additive compositions and methods of the present invention may be used in well bore drilling, cement production and delivery systems, and fracking operations.
