Abstract

The article is devoted to the modernization issues of laboratory units designed for the concrete carbonation study. General pre-conditions for accelerated tests as well as developments of respective units are given. The article provides a rationale for the choice of carbon dioxide volume concentration and temperature and humidity conditions in a chamber. The article describes some variants of units with indication of their pros and cons and introduces a unit for carbonation of concrete with a humidifier and automatic control system.
