The properties of aggregate can have a significant effect on the thermal properties of concrete because aggregates make about 70 to 80 volume of concrete. ... The fineness modulus values of the natural sand and FNS were 1.9 and 4.1 respectively. The combination of 50 FNS with 50 natural sand produced a wellgraded fine aggregate.
Fineness Modulus of Sand for Concrete Fineness of fine aggregate is related to term fineness modulus most commonly sand Fineness modulus is a measure to define fineness of aggregate precisely it defines coarseness or fineness of aggregate to be used in concrete . ... 92 Effect of Quartz sand
Fineness modulus 2.69 . ... provides a viable alternative for river sand in concrete. Investigations on the use of stone crusher dust in concrete as an alternative to river sand are presented in ...
The objective of this study is to examine the workability and various mechanical properties of concrete using artificial lightweight aggregates produced from expanded bottom ash and dredged soil. Fifteen concrete mixes were classified into three groups with regard to the designed compressive strengths corresponding to 18 MPa, 24 MPa, and 35 MPa.
2019-11-11The study examined the effect of the recycled HCB on fresh and hardened C-25 concrete properties and the possible replacement percentage of river sand by those recycled fine aggregates. The research also examined the comparative properties of the two recycled fine aggregates.
2019-7-1sand of maximum size 4.75mm. By IS 383-1970, it is ratified to grading zone-II against specific gravity of 2.60 and fineness modulus of 2.25 was applied in this investigation. Coarse aggregate Coarse aggregate obtained from nearby granite quarry has
Sand with fineness modulus of about 3.0 or more is preferable to obtain a workable concrete mix with limited amount of water, and for enough fine material c ement i n the mix to obtain the required consistency Natural Sand from Al-sadoor region with fineness modulus, specific gravity and
2016-4-30Before starting the various tests on concrete, the physical properties of the raw materials were determined. These properties are fineness modulus, specific gravity water absorption etc. Sieve analysis was performed to determine the fineness modulus of copper slag, sand and coarse aggregate. The specific gravity of sand and
2017-8-5material such as sand, gravel, crushed stone, blast-furnace slag, and lightweight aggregates that usually occupies approxi-mately 60 to 75 of the volume of concrete. Aggregate properties significantly affect the workability of plastic concrete and also the durability , strength, thermal properties, and density of hardened concrete.
The dividing line between fine and coarse aggregate is the 38-inch sieve. The fineness modulus FM is an index of the fineness of an aggregate. The FM is calculated by adding the cumulative percentages by mass retained on each of a specified series of sieves and dividing the sum by 100 see Table 1.
The present study prepared 15 concrete mixtures to examine the effect of the natural sand content on the workability and mechanical properties of concrete using Korean artificial lightweight aggregates. Slump, air content, and segregation was measured in the fresh concrete.
2018-10-10the slump decreases due to a re duction in the fineness modulus and the negative effect of CFBC particles. This study also shows that utilizing the proper amount of CFBC bed ash in mortar significantly improves sulfate resistance. I. INTRODUCTION Circulating fluidized bed
