Abstract
The effects of incorporating two commonly used types of antiwashout ad mixtures (AWA), welan gum and hydroxypropyl methyl cellulose (HPMC), o n properties of hardened concrete are investigated for mixes with wate r-cement ratios (w/c) ranging between 0.30 and 0.60. Compressive stren gth, flexural strength, and modulus of elasticity development up to 3 months, as well as bond with reinforcing steel, apparent chloride ion permeability, and pore size distribution are evaluated.
