An investigation was carried out to study the influence of two types of anti-washout admixtures (AWAs) on the performance of underwater concrete. specifically. workability and washout resistance. The tested AWAs were hydroxypropyl methylcellulose (HPMC) and polyacrylamide (PAM) as nonionic AWAs and carboxymethyl starch (CMS) and polyanionic cellulose (PAC) as anionic AWAs. https://allfixelectricales.shop/product-category/universal-oven-knob/
