Abstract
The subject of the invention consists in the admixture for processing of concrete mixtures by heat curing, which results in the increase of the final solidity of concrete parts and concrete products.This admixture contains mother liquor from production of pentaerythritol, containing sugars of formaldehyde in the following quantities: up to 5 percent by weight of formose, from 4 to 15 percent by weight of pentaerythritol, from 5 to 35 percent by weight of formate, from 1.5 to 31 percent by weight of condensation products of formaldehyde and acetaldehyde, and up to 1 percent by weight of formaldehyde calculated per water solution containing 40 percent by weight of dry matter.
