“…Дозировка модификатора составляла 0,5 % от массы цемента (соответствующая рекомендациям всех производителей). Для проведения исследований применялись отработанные на производстве составы с оптимальной гранулометрией заполнителей [2][3][4][5][6][7][8]. В/Ц соответствовало заданной удобоукладываемости и формуемости изделий методом полусухого вибропрессования.…”

In the article the method of volumetric hydrophobization by insertion of modifying agents with hydrophobization effect directly in concrete mixture on the stage of mixing is considered and the degree of their influence on physics-mathematics properties of vibropressed products which made on technological line with optimal granulometry, water to cement proportion and parameters of forming is estimated, so that the geometrical dimensions of moulded products satisfy required sizes and limits, and appearance of front-face area satisfied A3 category. There was established the increase of operational characteristics of concrete walkway vibropressed slabs when in use of polyfunctional modifying agents with hydrophobization effect – Murasan BWA 17 and SikaPaver AE-2 in 0.5 % cement weight quantity, wherein there was found the increase of compressive strength of slabs on 23 %, frost resistance on 50 cycles and decrease of water absorption up to 45 % which allows increasing the longevity of small-pieces products. Insertion of volumetric modifier-hydrophobisator Akvasil, only with a mono-characteristic to decrease of water absorption, has negative role on strength characteristics of vibropressed products with decrease of concrete compressive strength by 12 %.
