ECO FRIENDLY CONCRETE FOR SUSTAINABLE STRUCTURES
The present article contemplates the study of eco friendly concrete by substituting Portland cement (PC) for very high levels of limestone filler (LF) in binary and ternary mixtures with fly ash (FA) in proportions of 50 to 80%, with ratios 0.25 a/b and optimization of the particle size. Results of compressive strength, CO2eq emission, energy consumption and binder intensity are presented, with which comparative indices were calculated to observe the performance of the mixtures. From the point of view of sustainability, it was possible to prepare concrete with a compressive strength of 51.8 MPa, at 91 days, with 77 kgCO2.m-3 of concrete, where 80% of the PC were replaced by 70% of LF and 10 % of FA, with consumption of only 97 kg.m-3 of PC (87 kg.m-3 of clinker) and 104 L.m-3 of water. The study shows the achievement of structural concrete with fck of up to 80 MPa with very low CO2eq emissions and energy consumption, through the use of high levels of mineral additions (MA) and reduced environmental impact.
