Application of mutiple linear regression analysis in polymer modified mortar quality control

Abstract

This paper is to predict the effect that the mixing charging, mixing water, and admixture and temperature to the quality control of the polymer modified cement mortar using the regression analysis method.With the water cement ratio and ploymer-cement ratio of a kind of polymer modified cement mortar as the dependent variable, the compressive strengh and flexural strength on quality control as the independent variables, the regression equation is established and the prediction interval result is achieved,which tested that there are multiple linear relations between the quality control's aims and the factors affecting the PCM's quality. © the authors.
