The Fundamental Properties and Planting Experiments on the Concrete with Continuous voids

다공성콘크리트의 기초적 특성과 녹화실험

The concrete with continuous voids (No Fine Concrete ; NFC) is the new planting material which may be used for stabilizing the sandy slope of river or road sides. The components of NFC are mainly coarse aggregate and low alkali cement paste, so to speak fine aggregate is not used. This report shows the fundamental properties of NFC, such as continous void ratio, compressive strength, permeability. As experimental results we can get the good quality of NFC, that is about 28% continuous void ratio, about 120kg/$\textrm{cm}^2$ compressive strength and high flowable permeability. And also planting grass and garden portulaca on the concrete with continuous voids is resulted in success.
