Concrete Blocks Manufactured Using Sequestered Carbon Dioxide

摘要: A novel approach to beneficially using carbon dioxide produce concrete blocks was investigated during a pilot demonstration. retrofit system inject gaseous attached conventional mixer medium weight block mix design and curing. The injected into the mixing cycle. gas thereby absorbed form thermodynamically stable carbonate reaction products distributed throughout matrix. effects of on temperature, compressive strength, density, absorption were examined. carbonated required simple modification through water increase. found display improved performance relative control at 7, 28 56 days. sequestered in product as nano-scale products. treatment served improve environmental footprint treated blocks.
