Is lightweight concrete chemically compatible with common admixtures?
Lightweight concrete is compatible with common concrete construction admixtures; however, most common admixtures are added to plain concrete to effect a change in the characteristics of the concrete that are not applicable to lightweight concrete application performance. As an example, lightweight concrete needs no air entrainment or finishing aids; however, color admixtures and strength enhancing admixtures work well if they are applicable to the project. • What additives are common to cellular concrete? Fiber reinforcement Heat-of-hydration reducers (iced water or chemicals) Compressive strength enhancers Coloring pigments or color enhancing admixtures • What is the correct water to cement ratio for the cement water slurry? Typically, a .5 water to cement ratio slurry consisting of two parts cement to one part water is typically used as a base mixture for lightweight concrete. The water cement ratio is varied according to specific project requirements. We should note that lightweight
