Portable Concrete Batching Plant 5 Cubic Yards 2CL-5 | Mix

The 2CL-5 portable concrete batch plant has a single bin capacity of 5+ cubic yards. This mobile concrete batch plant can be towed into very remote job sites where materials can be loaded on-site. Like all of our automated batch plants, set up is as easy as finding semi-level ground, lowering the leveling jacks, and firing up the engine.

ASTM C138 - ACI Density, Yield, and Air Content of Concrete

To figure out the density, you are filling up a container with concrete. This container must have a known volume (4), minimum .20 cubic feet. First weigh the empty container (1) and record that value to the nearest tenth (.1) of a pound. After performing the proper procedures for filling the container (i.e. filling it in three lifts, mallet blows, rodding, striking off with strike-off plate), follow these steps:

Volume Batching of Concrete - Theory & Example Calculation

Before batching concrete ingredients in terms of volume, we need to know two things. What is the relative proportion of concrete ingredients in terms of volume? What is the water-cement ratio? After knowing these two things you can proceed to batch concrete ingredients in field.

Batching, Mixing, Placing and Compaction of Concrete

Batching is the process of measuring concrete mix ingredients either by volume or by mass and introducing them into the mixture. Traditionally batching is done by volume but most specifications require that batching be done by mass rather than volume. Percentage of accuracy for measurement of concrete materials as follows.

(3) adjustments to batch weights based on trial mix . Water/cement ratio (w/c ratio) theory states that for a given combination of materials and as long as workable consistency is obtained, the strength of concrete at a given age depends on the w/c ratio. The lower the w/c ratio, the higher the concrete strength.
