An evolutionary approach to modelling concrete degradation due to sulphuric acid attack [PDF]
, 2014 Concrete corrosion due to sulphuric acid attack is known to be one of the main contributory factors for degradation of concrete sewer pipes. This paper proposes to use a novel data mining technique, namely, evolutionary polynomial regression (EPR), to ...
