WebAll methods are for evaluating the carbonation resistance of concrete mixes by comparison with a concrete mix with known carbonation resistance. It is not a method for the determination of carbonation depths in existing concrete structures. A specimen is a concrete prism. Sample will be exposed to high concentrations of Webits use, will be minimal. Sustainable concrete should have a very low inherent energy requirement, be produced with little waste, be made from some of the most plentiful resources on earth, produce durable structures, have a very high thermal mass, and be made with recycled materials. Sustainable constructions have a small impact on the ...
WebConcrete surfaces with poor durability have been a problem on some highways in California. In an effort to find means of improving surface durability, particularly of wearing surfaces, a research project was initiated by the Materials and Research De partment. WebDurability design provisions under the current concrete design standard NZS 3101:19954do recognise that SCMs can enhance concrete durability, but saw their use as an alternative to the prescriptive solutions specified for concrete produced with ordinary Portland cement.
