Manufacturing forms. You can buy them (prefabricated), but you can do it yourself. You will need boards, in which one of the parties must be carefully brushed. A “pencil case” is knocked out of them, into which bridges are inserted, dividing it along the entire length into compartments. Such “inserts” can be cut from moisture-proof puff plywood. Previously in the boards, according to the previously produced marking, cuts are made under the “inserts”.
The dimensions of the cells determine the dimensions of the future blocks, so they are selected depending on what parameters the artificial stone should have. To speed up the process of production of aerated concrete, several different forms should be prepared, for all the necessary sizes.
To prevent the mixture from sticking to the boards, the internal surfaces of the cells are abundantly oiled with waste oil diluted in water (3 parts) (machine oil – 1 part). (more…)
