Method for spraying the underground excavation walls with concrete using the mixture based on fly ashes from the use of fossil fuels to produce energy

摘要

method torkretowania walls underground workings, using mixture based on the ashes of volatile energy with use of fossil fuels and water treated carbon dioxide, with the intention of sealing and strengthening area of the workings, is that during the process of p rzygotowania mixture torkretowania in proportions by volume fly ash and water from 1: 0.5 to 1: 2 and its application on wall excavation, to aggregate to torkretowania wtu0142aczany is gas co2 concentration not less than 1% relative to the air for a period of 5 - 60 minutes.
