Further fine aggregate failing to meet the fineness modulus requirement as river sand and coarse aggregate taken is dolomite limestone in crushed form read more the laboratory mortar is composed of cement as a binding material fine fineness modulus of sand table 3 so for the structure required high strength
In the present investigations the effect of fineness modulus of sand has been investigated the fine aggregate sand taken is yamuna river sand and coarse aggregate taken is dolomite limestone in crushed form it has been sorted in several categories starting the fineness modulus
Jul 16 2020 the change of the fineness modulus of sand and the quality of stone will lead to the change of concrete aggregate quality in addition to the change of cement water quality watercement ratio curing temperature and humidity concrete age and construction method it will cause a change in concrete quality therefore how should we ensure
Jun 30 2015 many agencies use fineness modulus variation as a convenient means of keeping quality history data on uniformity of particlesize distribution of aggregate production delivery and use some agencies require that aggregates be processed to remain within upper and lower limits of fineness
