    Determination Of Concrete Compressive Strength: A Novel Approach

    Concrete compressive strength based on measured acceleration using Artificial Neural Network (ANN). The surface of a cube was struck with an impactor and induced acceleration reading at six different locations on it were recorded. Strength of concrete was determined by testing. Using ANN, the multi-dimensional six acceleration readings were given as input and the same mapped to a single output of concrete strength.

    3.3 Concrete strength is affected by the location of the concrete in a structural element, with the concrete at the bottom tending to be stronger than the concrete at the top. Core strength is also affected by core orientation relative to the horizontal plane of the concrete as placed, with strength tending to be lower when measured parallel to the horizontal plane. 3 These factors shall be considered in planning the locations for obtaining concrete samples and in comparing strength test
