Water-Reducing concrete admixtures. Water-reducing is a type of concrete admixture that is chemical products. When any of these chemical products are added to concrete, it can create a desirable slump despite the lower-cement ratio. These admixtures are also used to gain specific concrete strength with the use of much lower cement content.
