The presentation of the “Prof AC” semiautomatic conveyor-type line for producing aerated concrete blocks. The estimated productivity of the line is 70 cub.m per shift. This video presents the production process of aerated concrete blocks using “Prof AC”. Producing aerated concrete blocks starts with mechanized supplying and automated dosing of fill materials to produce aerated concrete. Having been dosed, the components and water are loaded and mixed in a mixer-activator. Preparing an aluminum suspension and preparing cement-sand mortar are carried out simultaneously. The aluminum suspension is the last component that is loaded into the mixer-activator. Once the aluminum suspension has entered into a chemical reaction, the aerated concrete is poured into a metallic mold, which is transported to a heating chamber where aerated concrete mixture rises and gains the initial strength. After curing for 3-4 hours, the monolith in the mold is supplied to a cutting area where mold’s sides are mechanically removed and the aerated concrete monolith is cut into blocks. The cut blocks are transported on the trolley to a chamber to get a warehouse strength. Gaining the required strength, the blocks are supplied to a packaging area for palletizing and packing blocks onto a transporting pallet. Samples of aerated concrete blocks, which have been selected during production process, are tested at the lab to certify the conformity of a finished product with construction rules and standards. An accurate geometry of aerated concrete blocks allows to build walls using adhesive layer of 3mm.
