Experimental Study on Improving Concrete Carbonation Resistance with Silane Impregnation

摘要

Silane impregnation effects on concrete carbonization resistance are systemic researched, through determining blank and silane impregnation specimens' carbonation depth, forming 6 mixture ratio cement mortar, treating with silane impregnation and then curing to 30d, 60d, 90d and 180d age naturally. Through XRD microscopic and water absorption test, the improving carbonization resistance mechanisms are analyzed from two aspects including cementations material hydration product concrete pore humidity.
