mar 21, 2021 the size range limitations need limestone dust to have a certain level of fineness. on size analysis the stone dust must not be less than 95 by mass pass through a 250 micrometre sieve the dry dust which passes the sieve must be between 60 and 80 by mass passing through the 75 micrometre sieve.
3 fineness modulus 2.66 quarry dust was obtained from local quarries. quarry dust with fineness modulus 2.952, 3.254, 2.80 was considered for the study, the sieve analysis results and other properties are tabulated below in table 4 to 7 table 4 sieve analysis results for quarry dust 0f fineness 2.952 1000gm weight retained(gm) cumulative passing
in this paper, the replacement of cement by micro fine quarry dust (mfqd)- a white material produced by-product from the quarry, in concrete mixture seen to be a reliable source in terms of strength and the fineness test was carried out based on bs en 196-62010 10. the
quarry dust to mixes is limited due to its high fineness. its addition to fresh concrete would increase the water demand and consequently the cement content for given workability and strength requirements. thus, the successful utilization of quarry dust in scc could turn this waste material into a valuable resource. 2 another potential
