CONCRETE MIX AND ENVIRONMENTAL LOAD IN THE CONTEXT OF DURABILITY AND RELIABILITY

CONCRETE MIX AND ENVIRONMENTAL LOAD IN THE CONTEXT OF DURABILITY AND RELIABILITY

Paper in proceedings (conference paper)

The carbon dioxide is the primary greenhouse gas and its concentration in the environment has dramatically risen during the 20th century. According to some estimates, the Portland cement production is responsible for producing about 7% of total global CO2 emissions. This creates a challenge to minimize the use of Portland cement and maximize the use of industrial by-products such as silicate and aluminosilicate materials. The impacts of the use of such blended cements are the changes in physical-mechanical properties of concretes; however, it has also an effect on structure costing because industrial by-product as secondary raw materials might reduce the price of the binder. This should be taken into consideration when designing concrete structures, together with the required level of reliability and target service live. The consequences of those measures on the CO2 emissions and structure costing together with the durability and reliability indicators are studied utilizing software developed by authors.
