Dilute the cement

"Honest scammers" dilute the cement of ash only partially. Often this happens openly — the buyer knows what they sell to him and why the mixture has such a low price. But the great Slavic gods of a freebie, maybe they overpower common sense-the foreman or contractor is seduced by a favorable price, and the eyes are closed to the “small” loss in qualities. If the construction is large, then attempts are made to “save” a fake mixture — on the facility it is mixed with bags of high -quality cement.
