Cinder block is a popular building material that is widely used due to its low cost and good performance. will last 50 years or more. The equipment intended for the production of this building material is not subject to certification, so many manufacture.
What is needed for the production of blocks, mold making
In order to make a cinder block with your own hands, it is necessary to purchase in large quantities all the components of the mixture, which necessarily includes cement and fillers, as well as various additives that improve the quality of the building material.
For production, you will need a concrete mixer, a vibrating sieve and a vibrating machine. Particular attention should be paid to the molds for making blocks.
You will need as many forms as there are blocks you are going to make per day. Forms can be made of both wood and metal. For void formers, pipes of the required diameter are taken. You can also make rectangular void formers, but keep in mind that the voidness of the block should not exceed 40%.
Foreman's advice: the usual block sizes are 390x190x188 mm, but if you make blocks with your own hands, you can make shapes of arbitrary sizes.
You can also make machines for the production of cinder blocks with your own hands. Detailed drawings will help in this.
If you have a lot of time, then you can make blocks without using the machine only with the help of forms. To do this, you need to pour the solution into it by a third, and then tap its walls around the entire perimeter with a hammer so that the mixture sits down. Then you need to pour the mixture again and repeat the action. Plastic bottles filled with water can be used as void formers. They need to be inserted at the same distance from each other. In this case, it will take 2-4 days to dry, after which the block can be removed and a new one prepared.
When using high-quality cement and strictly following the production technology, do-it-yourself blocks turn out to be of no less quality than those produced at the enterprise.
