Selects practical proportions of cementitious material, water, aggregate and admixtures for a required concrete performance.

Plain-language explanation

What the test tells you.

The project specification controls the exact method and acceptance requirement.

Material properties and project requirements are used to calculate trial proportions, which are then mixed and tested.

Approved constituent materials, calibrated batching equipment, mixer and fresh/hardened concrete test equipment.

A proposed mixture and trial evidence for workability, density, strength and other specified performance.

Supports economical production of concrete that can be placed properly and achieve the required performance.
