Development of Mathematical Model to Predict Increase Rate of Compressive Strength Influenced By Metakaoline Substance for High Strength Concrete

The study try to monitor the strength development of concrete modified with metakaoline content, this addictive has been applied in mix design for high strength concrete, the study monitor the behavior of concrete modified metakaoline content at different mix design concept, these are under various water cement ratios proportion, the rate of strength achieved from various water cement ratios were observed in the study to predict the behaviour of the material modified with this addictive’ s, the application of deterministic modeling techniques were observed to express the decrease and increase rate of concrete strength development, these developed model generated simulation parameters that express the behavior of high strength concrete from mix proportion modified with metakaoline content. The study expresses simulation that predicts the compressive strength at every twenty four hours. Validations of predictive model were carried out, and both parameters generated favorable fits.
