High-Strength Concrete - cementorg

Producers of high-strength concrete know what factors affect compressive strength and know how to manipulate those factors to achieve the required strength In addition to selecting a high-quality portland cement, producers optimize aggregates, then optimize the combination of materials by varying the proportions of cement, water, aggregates, and admixturesDesigning a High Strength Concrete Mix| Concrete ,Designing a High Strength Concrete Mix If high ultimate strength- strength at 28 days or later- is the aim, the steps available to achieve it include using: (1) a high cement content; (2) a low water/ cement ratio and (3) a water-reducing admixture The use of a high cement content will ordinarily produce higher ultimate strengthSeven Must-Use Concrete Admixtures (Additives),
