Crush Sand Required Fineness In Cement Concrete
Fineness Modulus
Cement was an ASTM type I Portland cement; a natural sand was used for preparing mortars ( modulus fineness). Sikatard was used as setting retarder (phosphatebased additive) and SikanolM as plasticizer. OFA samples were studied by several techniques: Thermogravimetric analysis (TGA850 Themogravimetric Measuring Module, MettlerToledo), Scanning electron microscopy (JEOL JSM .
