PROCEDURE FOR THE PREPARATION OF CEMENTITIOUS CELLULOSE-CONTAINING CONCRETE PRODUCTS WITH REDUCED WATER ABSORPTION PROPERTIES, AND USE OF THE CONCRETE PRODUCTS OBTAINED

摘要

The invention relates to the procedure for the preparation of cementitious cellulose-containing concrete products with reduced water uptake properties, with the use of a component of high cellulose-content. According to the method of the invention the cellulose-containing component, cement, water and optionally a homogenized mixture containing known additives are suspended before curing with 1-20 wt% vegetable oil by weight of the mixture, as a step of manufacturing the concrete product.
