Slump Test - an overview

The mini slump test is performed for the analysis of flow behavior of cement to check the workability, according to Standard ASTM: C-143. In the freshly prepared cement paste, small particles interact via colloidal forces, such as Van-der Waals, electrostatic repulsion, steric hindrance, and hydrogen bonding, and some bigger particles interact via direct contact like friction or collisions.

Fundamentals of Concrete

The batch plant operator must ensure that the amount of free-water in the mix does not vary from that called for in the mix design. Batch plant operators monitor aggregate moisture to determine if there is any free-water in the aggregate or if the aggregate is so dry that it will absorb water that is added to the mix.

Ready-mix concrete

Volumetric trucks often have a lower water demand during the batching process. This will produce a concrete that can be significantly stronger in compressive strength compared to the centralized batch plant for the same mix design using the ASTM C109 test method. Centralized batch systems are limited by the size of the fleet.

What Yield Can Do For You| Concrete Construction Magazine

Yield is determined as batch weight divided by density. This is converted to relative yield, which is the total volume of the concrete received divided by the volume the producer intended to provide. If relative yield is 1.00, then it's exactly the same. But this is expressed as cubic feet per cubic yard.
