Strength Properties of Carbonate Filled Concrete

It has been shown by numerous experiments that, according to the properties of carbonate aggregates, higher grade concretes can be obtained than other types of aggregates of similar strength. The strength of concrete obtained from high-strength and high-strength carbonate rocks reaches a value of 600 kg/cm² and above. Aggregate concretes made of porous carbonate rocks have a strength of 100 to 400 kg/cm², depending on the group of aggregates.

Laboratory work was carried out at  Tashkent Chemical Technological  Institute (TCTI)  on the direct dependence of the strength of concrete on the bulk density and hardness balance of carbonate rocks added to it. Experiments conducted here have confirmed that it is possible to obtain carbonated filler concrete with a strength of 500 kg/cm² and higher.
