PREDICTION METHOD OF NEUTRALIZATION DEPTH OF CONCRETE SUBJECTED TO APPLICATION OF FINISHING COATING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a prediction method of a neutralization depth of concrete subjected to application of a finishing coating material.;SOLUTION: A neutralization resistance value R of the finishing coating material is determined from formula (2), by using a thickness d and a CO₂ diffusion coefficient D_f of the finishing coating material acquired from measurement relative to the finishing coating material, and the neutralization depth x is predicted from formula (1), where A is the neutralization speed coefficient of concrete (known), t is material age, and D_c is the CO₂ diffusion coefficient of the concrete (known).;COPYRIGHT: (C)2010,JPO&INPIT
