Пропитка под давлением цементной суспензией позвол ет повысить прочность при сжатии через 28 суток на 20% при расходе цемента 240-300 кг/см и на 50-60% при расходе цемента 193 кг/м бетона. Эффективность пропитки тем больше, чем меньшеImpregnation of cement slurry under pressure makes it possible to increase compressive strength after 28 days by 20% with cement consumption of 240-300 kg / cm and by 50-60% with cement consumption of 193 kg / m concrete. The effectiveness of the impregnation is greater than less
