COMPARISONS OF LINEAR REGRESSION MODELS FOR PROPERTIES OF ALKALIACTIVATED BINDER CONCRETE

摘要: Concrete with alkali-activated binder (AAB) is increasingly considered as a better alternative to conventional portland cement (PC) concrete due its superior sustainable and green properties. In order promote the practical usage of AAB concrete, previous study by present authors proposed models on correlations among their mechanical nondestructive The extends knowledge proposing new improved using linear regressions predict compressive strengths modulus elasticity from ultrasonic pulse velocities. are developed for both unstressed stressed different curing temperatures. accuracies compared sum squares errors (SSE) R 2 depending type equations; found be more accurate models.
