Discussion: Relationship of moisture content with temperature and relative humidity in concrete

摘要

Measurements of moisture content for a series of concrete were conducted to analyse the impacts of water to cement (W/C) ratio and temperature on the moisture content-relative humidity (RH) curves (Jiang and Yuan, 2013). Based on the experimental results and the multi-layer molecules adsorption Brunauer-Emmett-Teller (BET) analysis, the authors proposed a three-parameter model to capture the relationship between moisture content, temperature and RH in concrete (Equation 7 in Jiang and Yuan, 2013) 8. S=λ_1H/(1-λ_2H)(1+λ_3H) where S is the pore water saturation, H is the RH in concrete, and λ_1, λ_2 and λ_3 are the adjustable parameters.
