原位合成SAR表层处理混凝土的碳化性与氯离子渗透性研究
Study on the Carbonation and Chloride Ion Penetration of Concrete by Surface Treatment Using Super-absorbent Resin
摘要
Abstract
According to performance features of the super-absorbent resin (SAR) water swelling, this paper passes to surface treatment of concrete by synthesizing super-absorbent resin in situ. The carbonation and chloride ion penetration of concrete with SAR surface treatment pre and post are studied; the correlation of carbonation depth- initial current- electric flux is established. The results show that: the SAR in the concrete surface layer becomes expansion hydro gel after absorbing water or moisture and compacts the surface concrete pores, which improves the carbonation resistance and chloride permeability of concrete with treatment; as carbonation age constant increasing, the initial current and chloride ion dielectric flux are greatly decrease; the carbonation depth and electric flux are negative related.关键词
