Concrete additives for mixtures with artificial sand, whether in combination with natural sand or not, need to incorporate air in controlled quantities to minimize the negative effects of the crushed sand. One solution is to add a water-reducer to the concrete mix. This type of additive disperses cement grains and small particles by electrostatic repulsion and reduction of surface tension. In
