· In this respect the utilisation of quarry dust could play a part in lowering the supply cost of SCC which is currently some 80 150% higher than that of normal concrete In Sweden the application of SCC is well established and according to Petersson [16] the cost of SCC is only 10 15% higher while in France [17] the cost is 50 100% higher than normal concrete
Sand M Sand and Quarry Dust Sand as a substitute for river sand become inevitable To overcome from this crisis fully replacement of sand with M Sand and Quarry Dust can be an economic alternative In this project determine the concrete s strength and durability by using M Sand and Quarry Dust as sand and comparing with the conventional mix Wide range of 28 days of healing are considered
From test results it was found that the maximum compressive strength is obtained only at 50% replacement at room temperature and net strength after loss due to hike in temperature was above the recommended strength value due to 50% replacement itself This result gives a clear picture that quarry dust can be utilized in concrete mixtures as a good substitute for natural river sand giving

Tests were carried on mortar cubes to study mortar compressive strength and on concrete specimens Two basic mixes M20 and M25 were considered in the study Tests indicate the relation between variations of compressive strength with the fineness of quarry dust I INTRODUCTION Concrete is the most widely used construction material today The constituents of concrete are coarse aggregate fine
The tests were carried out to find the compressive strength splitting tensile strength and flexural strength on specimens Results showed that up to % replacement of cement by quarry dust there was no reduction in compressive strength splitting tensile strength and flexural strength The experimental work was carried out with M sand confirming to zone II as fine aggregate in concrete
While Quarry dust QD defined as the material less than 4 mm machine Corresponding author 10% limitation as stated in ASTM C 618 2021 [9] stated that the LOI shows the extended of carbonation and hydration of free lime and free magnesia due to the exposure of cement to the atmosphere Physical properties fineness and specific gravity of OPC and MFQD were tabulated in Table 1 In
Quarry Rock Dust as hundred percent substitute for Natural Sand in concrete Design Mix for M30 and M40 has been calculated using IS 10262 2021 for both conventional concrete and quarry dust concrete Tests were conducted on cubes cylinders and prisms to study the strength of concrete by using Quarry Rock Dust and the results were compared
The effect of quarry dust on compressive strength and split tensile strength was investigated and from the overall result obtained it was observed that the compressive strength and split tensile
river sand with quarry dust without the inclusion of fly ash resulted in a reduction in the compressive strength of concrete specimen It has also been reported that the reduction in the compressive strength of quarry dust concrete was compensated by the inclusion of fly as into the concrete mix Reddy and Reddy 2021 reported an increasing
Need for quarry rock utilisation These residues are generally less than 1% of aggregate production In the normal concrete the introduction of quarry dust for mixing is limited due to its high fineness And it is available at low cost and locally available material [28
observed was that of quarry dust in which 100% passing for a sieve size of and a few particles retained on the sieve accompanied a distribution from fine sand to fine gravel The fineness modulus was and for gravel and quarry dust respectively These values fall within the limit
· To determine the number of cement particles larger than 90 µm or Fineness test of cement The following apparatus is used 100g of cement test sample Weighing balance which can weight with an accuracy of 1mg Standard Sieve of size 90 µm Sieve pan with lid Sieve Shaking Machine optional Procedure for finding Fineness test of cement Take a sample of cement and rub
Fineness test of cement is done to determine the particle size of cement As the rule of thumb the finer the cement particle the best will be the cement and on the other hand the coarser the particle it will not be that good The fineness of cement is determined by two methods; 1 Sieving Method 2 Air Permeability Method Blaine Method
The result shows that when sand is replaced by 40% it gives strength upto Mpa in 7 days and Mpa in 28 days for M20 and Mpa in 7 days and Mpa in 28 days for M25 From the above test result it is clear that Quarry dust can be used as fine aggregate in replacement of sand 1
and finding answers for limit the environmental effects connected each with quarry dust creation and its disposal The usage of quarry dust in bond and cement gives potential natural further financial points of interest for every related industry especially in zones wherever a considerable amount of quarry dust is composed In this analysis the experiment work is performed by using cement
SIEVE ANALYSIS AND FINENESS MODULUS Sampling Since the reason for sampling aggregates is to determine the gradation particle size of the aggregate it is necessary that they be sampled correctly The results of testing will re ect the condition and characteristics of the aggregate from which the sample is obtained Therefore when sampling it is important to obtain a representative sample
For 40% quarry dust concrete workability is and for 50% replacement of quarry dust concrete compacting factor was observed d The compressive strength results of quarry dust concrete cubes were obtained in the fourth series where M20 M30 and M40 grades of concrete with 20 30 and 40 percent replacement of quarry dust with water cement ration of are concentrated and the
Table Fineness of aggregates Fineness Modulus Nature of sand 1 Fine sand 2 Medium sand 3 Coarse sand Sand having a fineness modulus more than will be unsuitable for making satisfactory concrete The fineness modulus values obtained for sand quarry dust and coarse aggregate are given in Tables
Sieve Analysis Test For Quarry Dust The standard gradation and sieve analysis test is aashto t 27 and astm c 136 sieve analysis of fine and coarse sieve this is actually the definition for mineral dust in the vslulverized limestone is the most commonly manufactured mineral filler although other aggregate after processing from a quarryhe following table
Compressive strength tests were carried out with different proportions of replacements of FA with QDW It was observed that on 75% substitution of FA with QDW the compressive strength of concrete was within permissible limit for use in construction industry Key words Pozzolana Portland Cement Quarry Dust Waste Concrete Compressive strength I Introduction Explosion in population
The fineness modulus was determined as per IS 386 Part III 1963 Fineness modulus of natural river sand Fineness modulus of quarry dust Get Price Stone Dust in Concrete Effect on Compressive Strength obtained for 40% replacement of s and by crusher dust Quadri et al Stone Dust in Concrete Effect on Compressive Strength Its fineness modulus and Get Price Fineness
Quarry dust was used to replace sand at ratios of 75% and 100% and four different water to cement ratios w/c of and were studied and compared For a given w/c ratio it
The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries By replacement of quarry dust the requirement of land fill area can be reduc
