The influence of crumbly and dense carbonate strata on the properties of Portland cement was examined. It is established that the effect of appending a chalk to the cement is to increase normal consistency, the effect of appending a lime on this indicator is virtually unaffected. Adding of both additives in cements gradually reduces setting time. Corrosion resistance of cement samples with chalk and lime additives was investigated. It is proved that the effect of appending a dense lime on cement samples strength is minor compare to samples with chalk, but the effect of appending the last one on corrosion resistance of materials is slightly improves.
