Mixing is the same for all Doubell Machines. It is simply a case of finding a good ratio of cement, aggregate water. Below is a link to a more detailed outline

Our concrete compressive strength testing machines includes concrete strength testing moulds like Cube Moulds, Beam Moulds, Cylindrical Moulds along with Flexural Strength Testing Machine that are equipped with the latest designs and operating principle.

However there is a better way for a fraction of the cost you can build your own concrete block machine. Building a concrete block making machine is actually not that difficult. Plans,with complete instructions,are readily available and will enable you to build a machine which will produce 800 concrete blocks per day. The machine is built from new or used auto parts,sheet metal and a few odds and ends.

CGM moulds are applied on the machine to produce concrete elements. The moulds produced by CGM are designed and built within the company, based on specific requirements of the client. The moulds are designed to make high quality products, thanks to high vibration and high precision of the metal frames.

The machine makes CLC slurry with the lowest structural integrity without any aggregate. Typical concrete weighs 140150 lbs. per cubic foot. That CLC weighs 50 lbs. per cubic foot. I need to make concrete with aggregate weighing around 105120 lbs. per cubic foot.
