jul 02, 2020 the stone dust and ceramic waste are the replacements of natural sand and stone respectively. the developed composite is tested for various mechanical testing to know the strength under compression, flexural and shear. seven different types of samples were casted by varying the stone dust from to 100% in the interval of 20%.
ired grading and fineness modulus can also be achieved consistently in the case of stone dust. processed stone dust can improve both strengthand flexural through better bond compared to river sand. of stone dust have no impurities like silt, clay and pebbles. possess less curing time.
fineness modulus of fine aggregate is 275 it means the average value of aggregate is in between the nd sieve and rd sieve it means the average aggregate size is in between to as shown in below figure values of fineness modulus of sand fineness modulus of fine aggregate varies from 20 to more. view details
the sand is good if its fineness modulus is in the range of to the sand with fineness modulus less than this will be called fine sand which is not good for use. the sand with fineness modulus greater than this will be called
As fineness modulus of sand changes from 2.0 to 2.5 there is an increase in compressive strength from 43.07 to 49.00 mpa. i.e. strength increases by 14%. On the other hand by increasing fineness modulus from 2.5 to compressive strength increases from 49.00 to

the sand is good if its fineness modulus is in the range of to the sand with fineness modulus less than this will be called fine sand which is not good for use. get price is and in to a was not you of it the be he his but for are this that by on at they with which she or from had we will have an what been one if would who has her
Sep 01 2019 · title: concrete mix design- modification of the fineness modulus method author: myron swayze and ernst gruenwald publication: journal proceedings volume: 43 issue: appears on pages: 43 keywords: none date: abstract: comparison of three maximum size gradings of sand-gravel and sand-crushed stone mixtures in concrete has revealed that for each type and size of
menoss found that the fineness modulus used in experimental work was equal to 2.48, very close to the value obtained with natural sand. schumache obtained a fineness modulus value equal to 2.77 for the stone dust, while with river sand it was equal to 2.11. In this way, it is clear the relationship between the employment conditions of the
oct 14, 2016 the value is not equal to the average particle size, but it can accurately reflect the thickness of sand. the larger the fineness modulus, the thicker the fine aggregate. common concrete sand has a fineness modulus ranging from 3.7 to 1.6, preferably medium sand, or coarse sand plus a small amount of fine sand in a ratio of
the range of water cement ratio for high strength concrete according to russel et al 19,774 ranges from 0.42 to 0.25 using stone dust in south africa. from the results, maximum strength of 92.7 nmm was obtained and a minimum of 62 nmm
impact value: bulking factor: none of these view answer the value of finencess modulus for fine sand may range between: 1.1 to 1.3 to 1.6 to 2.2 to 2.6 view answer workspace report discuss in forum. 146. If the fineness modulus of sand is then the sand is graded as: very fine sand: fine sand:
oct 01, 2016 also read: bulking of sand what, why & how. fineness modulus. fineness modulus is an empirical factor obtained by adding the cumulative percentages of aggregate retained on each of the standard sieves ranging from 80 mm to 150 micron and dividing this sum by 100.
fineness modulus of crusher dust idee. fineness modulus for river sand crusher dust was found as 2.83 and 2.705 get price. stone crusher dust as a fine aggregate in concrete for paving blocks. the test results shows that the replacement fine aggregate by crusher dust up to 50% by crusher dust: fineness modulus: 3.13, specific gravity
finess modulus value of stone dust range formula for finess modulas of sand how To calculate fineness modulus Of crusher dust how To calculate fineness modulus Of crusher from stone crusher as rubbish is check fineness modulus of sand indian standard. indian standard for crushed for crushed stone sand indian standard for crushed for crushed
Sep 02 2015 · jan 01, 1994 the premise: aggregate of the same fineness modulus will require the same quantity of water to produce a mix of the same consistnecy and give a concrete of the same strength. before calculating fm, lab technicians perform a sieve analysis to determine the particle size distribution, or grading, of the aggregate sample.
jul 29, 2020 the mixed sand fineness modulus is not less than 1.8, and the ultra-fine sand fineness modulus is not less than 0.9. or more the mixed sand should pass through the test to obtain reliable data and can be used after it has been demonstrated that
jul 30, 2016 fineness modulus of fine aggregate varies from 2.0 to 3.m. fine aggregate having fineness modulus more than 3.2 should not considered as fine aggregate. various values of fineness modulus for different sands are detailed below. fineness modulus limits for various zones of sand according to IS 970 are tabulated below.
