The addition of a small amount of sand will increase the strength. Using the manufacturer's recommendations, place the cement, sand, (aggregates if making concrete), and water into separate plastic buckets. The mechanical properties of traditional pervious concrete are insufficient, which limits its application. Desired slump = 50-75 mm So , it has achieved desired workability by satisfying the requirement of 50-75 mm slump value . Because the concrete is always only seconds old, you get 100 % of the curing process in place where you want it.
