Title: Concrete Q&A: Chloride Concentration in Soil and Exposure Classes, and Cleaning Slabs During Tilt-up Construction
Publication: Concrete International
Appears on pages(s): 60
I’m designing a structure that will be exposed to chlorides in soil, so I’m reviewing the requirements listed in Table 18.104.22.168 —Requirements for concrete by exposure class, in ACI 318-
14.1 The chloride concentration in the soil is lower than the concentration in seawater, so can I specify concrete with a strength value between 2500 and 5000 psi (17.2 and 34.5 MPa), based on C1 and C2 exposure classes, respectively?
Does ACI provide recommendations on cleaning concrete slabs during tilt-up construction?
