concrete mix decreases.concrete mix decreases. • As the surface area of the aggregate increases the more water will be needed to maintain a given slump. • Coarser Surface Texture • Particle Shape • Particle Size Distribution • As the air content increas es, the strength of the concrete decreases. 4 • It’s a calculation:

Homemade Strength: Concrete Weights

2012/4/4 · Eventually though you want to find some cheap used iron plates because concrete weights are not a long term solution in my opinion. Even if they hold up, you'll eventually run out of space on the bar. Now I suppose you could probably get something like 500 lbs

How to determine concrete yield

S = volume of concrete produced per batch in cubic f e e t ; V d = volume of concrete which the batch was de-signed to produce in cubic yard s . N O TE: A value for Ry greater than 1.00 indicates an ex-cess of concrete being produced, whereas a value less than this indicates the batch to be short of its designed vo l u m e .

Correcting for Aggregate Moisture| Concrete Construction Magazine

The concrete producer will add extra batch water to account for dry aggregates, and hold back on batch water to compensate for wet aggregates. The amount of the adjustment depends on aggregate porosity, moisture condition, and batch weights, but it is not unusual for the amount of adjustment to be in the range of 1 to 3 gallons of water per yard, or 10 to 30 gallons in a 10-yard load.

Batching Concrete

To produce a uniform quality concrete mix, measure the ingredients accurately for each batch. Most concrete specifications require that the batching be performed by weight, rathcr than by volume, because of inaccuracies in measuring aggregate, especially

Use these values to manufacture all high performance concrete with corrosion inhibitor for this project, and periodically correct the batch weights to account for changes in the fine aggregate fineness modulus and aggregate moisture contents.

How to Make Lifting Weights From Concrete

Lifting weights made from concrete have certain advantages. One is the cost of concrete compared to metal alloy and cast iron. Another is that concrete doesn’t rust. Making your own concrete weights is not complicated. A sand casting mold is easy to put together and you can form the casting to any size.

Aggregate Moisture and Making Adjustments to Concrete

concrete will absorb water from the batch water resulting in a lower slump. This water that will be absorbed by dry aggregates needs to be accounted for by adding additional water to the mixture. Therefore the aggregate moisture has to be measured and the amount of batch water adjusted accordingly.
