Carbonation of concrete is one of the main factors affecting its durability and structural integrity. This research work provides some analysis on the effect of mineral microtschliers on the carbonation process of modified concrete.Key words: concrete, cement, carbonation of corrosion, microtschliers, modification.The concentration of carbon dioxide in the Earth's atmosphere is not considered to be very high and is 0.03—0.045% (300-450 ppm) in dry air.In the XIX century, there was a progressive increase in anthropogenic emissions of carbonate anhydride into the atmosphere, which led to a violation of the carbon cycle and an increase in the concentration of CО2 (Fig. 1) [1].
