@@MaterialTesting Dear Engr, Now i am working as a laboratory technician in Saudi Arabia. i have some doubt related to concrete mix design. could you consider my doubt? 🙏
Dear Hamid, Weight/density=volume Hr material k weight ko density pe divide kren ge to volume aa jaen ge. Phr coarse n fine aggregate k volume ko cement k weight pe divide kren ge to ratios aa jaen gi..smjh na ae to btaeye ga.
Our target compression strength is 30 MPa for project requirement.. It is assumed.. And 5 MPa is factor of safety,.. So target strength is 35 Mpa. Mean k mix design k time mn sare weights accurate hte hain aur work site pe accurate nhi hte es lye factor of safety k lye compression strength ziada rakhi jati h..
Dear jamshaid Admixtures cement ka 1 se 3 percent dala jata h, os k lye admixtures provider manual dete hain jis mn admixtures ki percentage btaee hoti h..
