Workability sy murad hy k fresh concrete mix kitna workable hy. It means that concrete mix iss qabil ho k aasane sy pouring ke ja saky aur finishing easy ho aur vibrator use kia jaye to honeycombing na ho. saada alfaz main yun kaha jay ga k fresh concrete jitne naram ho ge utne workable ho ge. ya jitna water zyada ho ga workability zyada ho ge but zyada water strength ko reduce karta hy iss leay specified limits ko follow karna chahey. usually 100 to 125 mm slump (max limit for slump is 125mm) is good. aaj kal to oil type chemical (superplasticizar) sy concrete mixer truck main he workability ya slump ko high kar lya jata hy aur iss sy strength bhe affect naheen hote.
