aggregate crucing strength

Aggregates

Aggregates strongly influence concrete's freshly mixed and hardened properties, mixture proportions, and economy. Consequently, selection of aggregates is an important process. Although some variation in aggregate properties is expected, characteristics that are considered include: grading; durability; particle shape and surface texture

Compressive Strength of Concrete Cubes Lab Test Procedure

Concrete Strength Overtime. So we can't predict the strength until the concrete comes to that stable state. Once it attains certain strength at 7 days, then we know (according to the table) only 9% of strength going to increase. So at sites, we do normally test concrete at this interval. If the concrete fails at 14 days, then we will reject that batching.
