There are several different concrete ballast mixes you can choose from, such as: 1 to 5: A ratio of one part cement to five parts ballast is common for ordinary paths and paving slabs or concrete panels. This is a ballast mix that people use for its watertight properties, which you will certainly need when building walls using concrete panels.

Calculating the Amount of Ballast Needed. To determine how much ballast you need for 1m3 of concrete, you must first understand the composition of a 1m3 concrete mix. In a typical 1m3 mix, you'll have cement, sand, ballast, and water. The precise quantities of each component depend on the desired concrete strength and other factors.

If need be, add only a small quantity of water each time while watching out for the consistency and leave it to mix for about a minute before adding water again. vii. You may also use a sprinkler to wet the …

I'm needing to mix a small amount of concrete for porch foundations, I've got an Belle Minimix 150 and planning to use 14mm ballast. The ballast is available as 20 kg bags. Would a 6:1 ballast to cement ratio be suitable? If so would the mixer take a whole bag of cement, the bags of ballast + the water?

Ballast is often left out of screed concretes. The reason for this is to allow the finish to be as smooth as possible, which is obviously seriously hindered when you have big chunks of gravel in there. For these screeding mixtures is it common to just use sharp sand without the gravel. This mix is weaker than regular concrete, which is why it ...

The material is probably Zinc. The drum mount is made from zinc, it is part of the built in obsolescence in these machines, it slowly disintegrates over time. It can look like gray stones in the washer or drain filter. It will eventually break and the drum will wobble or stop spinning. It is expensive to replace.

Yep, the concrete makes the bill go down apparently. I was surprised to find that my front loader used about half as much juice (Killawatt meter tested both) as what my top loader had, even though I was using the highest spin speed for the front loader. Direct drive vs. belt drive and not running an agitator made the difference I suppose...
