Optimized Concrete Mix Design Guide by CreteForm
As you develop your concrete mix design, you'll find that cement serves as the primary binding agent, making up 10-15% of the total mix by weight. The water-cement ratio is particularly significant; you'll want to maintain it between 0.4 and 0.6 to guarantee proper strength of the concrete while maintaining workability.

Compared to conventional concrete, pervious concrete is simpler in constitution as it only contains paste and aggregate with monotonous size. During the mix design of pervious concrete, water to binder ratio (W/B ratio), binder or paste to aggregate ratios (B/A or P/A) and aggregate size and type need to be taken into consideration [8], [11], [12], [13].
