The goals of this study are to analyze the effects of high flowability concrete on CO2 emitted in the construction of a concrete footing and to evaluate the productivity treating CO2 reduction as added value. Higher flowability was effective in reducing emissions in the construction phase when compared to normal concrete, but the greater cement content of these mixes led to a much larger carbon footprint overall. Total production cost also increased with an increase in flowability. Consequently, value-added productivity when using high flowability concrete was lower than when using normal concrete. |
