A process for accelerating the pozzuolanic reaction with lime or lime - cement - mixing binders improved ground by co2 - enriched atmosphere

摘要

A process for accelerating the pozzuolanic reaction in soil, which with lime or lime - cement - mixing binders be improved by means of supply of co.sub.2₂:1. with a co₂ enriched air - or air - gas - mixture2. with a powder granular co₂-Carrier3. with a liquid co₂-Carrier4. with a pure co₂-Gaswith mobile construction machines or by means of stationary installations.By means of the co₂-Enrichment of one with a high lime - or lime cement mixture binder - - - addition - stabilized bottom, there is an accelerated reaction between the hydrated lime ca (oh)₂ and the co₂ and leads to the formation of caco₃ that is to say to verfelsung of the stabilized bottom. (Mono carbonate)In this way, the stabilized bottom at a ph - value 11 very rapidly to a resistant to frost bottom with high load-bearing values, for example, in road building and furthermore, up to a rock the left-hand side of the soil type.
