WebOnce that optimal fineness level is determined, maintaining a consistent grain structure becomes a critical factor in the quality of the final castings. Sand that is too fine (higher GFN) can create low permeability and result in gas defects. Sand that is too coarse (lower GFN) can create high permeability and lead to problems with metal ... Web4) High strength concrete was developed by using the same brand of cement available in market (having fineness value of 2975 cm2/g).Six trials were made to design the concrete mix. Concrete with water cement ratio, 0.28 and mix proportion of 1:0.75:1.75 with 1.7% by weight of cement super plasticizer was selected. 5) 6 concrete mixes were prepared by …
