5 Rules of Watertightness - National Precast Concrete Association
Nov 05, 2012 · Compare the leading causes of low durability versus high-quality concrete listed in Figure 2. A mix design for durable, watertight concrete should have a maximum w/c ratio of 0.45 and require a well-graded mixture of fine and coarse aggregates. The more excess water in a mix, the lower the strength, durability and watertightness.Learn More
