quarry dust as replacement for sand has been su p por t ed in the pr e vious study Manassa 2010 [5] showing that up to 20% of sand has been effectively replaced by quarry dust in traditional concrete Ilangovan et al 2008 [9] reported that the strength of quarry rock dust concrete was comparably 10 12% more than that of
REPLACEMENT OF CEMENT WITH FLY ASH AND QUARRY DUST AS FINE AGGREGATE SIVA RAO#1 K ADITYA NANDINI #2 #1 Student Structural Engineering MVR College of Engineering India augmenting the quality of concrete The utilization of Quarry rock dust which can be called as manufactured sand has been accepted
powder and quarry dust as a partial replacement of cement material Self compacting concrete was produced by partially replacing the cement by 10% 20% 30% Lime stone and Quarry dust powder and their influence on fresh properties such as passing and filing ability flowability are examined as per
Portland limestone cement river sand and quarry rock dust both of 2 mm maximum size as fine aggregate and 14 mm crushed rock coarse aggregate were used for the concrete The particle size distribution and the physical properties of the fine and coarse aggregates are shown in Fig 1 and Table 1 respectively The fine and coarse aggregates
The slump interaction plot of the GNP concrete with copper slag and quarry dust is shown in Fig 6 There are several factors that affect the workability of concrete including the water to cement ratio cement fineness type and quantity of
In addition to strength improvement quarry dust replacement yielded lesser cost and sustainable benefits which would promote the deployment of quarry dust in cement sand block production Read
replacement of sand as a major ingredient of concrete by quarry dust will be a techno economic solution to the above problem The present research work was carried out to study the ratio of total surface area of all the of GGBS and quarry dust replacing Cement and QD in M30 grade concrete 3
For mixes M20 and M25 quarry dust concrete with water cement ratio showed same slump as that of control concrete with w/c [28] In view of the above studies following observations are
Cost analysis indicates that the percentage of cost reduction on optimized cement quarry dust ratio concrete mixes stands between 27% to 31% than conventional concrete mixes It can be concluded
Utilization of quarry dust in concrete is recommended particularly in regions where sand is not easily available Dehwah [ ] Muhit et al [] determined that passing from mm of quarry dust with water cement ratio of are studied and the results are presented e In the h series M grade of concrete with
Gonçalves et al [29] and Shen et al [30] claimed that higher fine content in quarry dust increased water absorption rate which in turn increased water demand for mortar mix Therefore water to cement ratio was increased for concrete with quarry dust to sustain similar workability of conventional concrete [31 32]
This research was carried out to investigate the effect of partially replacing cement with quarry dust in cement sand mortar Tests including setting times water absorption compressive strength
Concrete with 50 % river sand and 50 % quarry dust performed better in flexure for both Bamboo Reinforced Concrete BRC and Steel Reinforced Concrete SRC at 28 days with strengths of N/mm
In this regard this study proposes to partially replace cement with aluminum dross and fly ash and partially replace natural sand with quarry dust Aluminum dross cement sand and quarry dust were used in a variety of proportions with a constant percentage of fly ash for the design of nine concrete mixtures
Nevertheless when incorporating waste quarry dust in concrete mixtures as partial cement replacement at 10% increments from 0% to 40% of the total cement content in constant water to cement ratio
Since the compressive strength is inversely related to the water cement ratio 28 days strength of 80% replacement of M Sand with quarry dust powder was found to be the least It can be inferred from the results that using quarry dust powder in concrete blocks as a replacement for fine aggregates is an economic effective and sustainable
The typical setup for measurement of top and bottom temperatures in the slab is shown in Fig 5 and the grade obtained were shown in the subsequent Table 5 Table 6 Table 7 for the conventional concrete slab quarry dust concrete slab and M−sand concrete slab recommended with the purpose of the ceiling affirmative and
The study was carried out on M20 grade concrete with water cement ratio Quarry dust can be used as fine aggregate but it has to satisfy the technical requisites like workability and strength Concrete mixes were tested for compressive strength and split tensile strength of concrete replaced by quarry dust was compared
Cost analysis indicates that the percentage of cost reduction on optimized cement quarry dust ratio concrete mixes stands between 27% to 31% than conventional concrete mixes It can be concluded
This waste known as quarry dust QD stems from the stone crushing industry and is abundantly generated reaching approximately 200 million tonnes annually Wellala presents the properties of concrete using quarry dust as a partial substitution of sand The authors found a significant drop in slump with the increase in percentage replacement
We adopted a comprehensive analytical model to estimate the amount of CO 2 that had been absorbed from 1930 to 2019 in four types of cement materials including concrete mortar construction
For non structural applications such as mass concrete mix ratios that falls below the minimum CS line may be utilized but care should Okafor F & Egbe E 2017 Models for predicting compressive strength and water absorption of laterite quarry dust cement block using mixture experiment Nigerian Journal of Technology 36 open in a new
with quarry dust for the same w/c ratio Concrete does not give adequate workability with increase of quarry dust Itcan be due to the extra fineness of quarry dust Increased fineness require greater amount of water for the S No Water cement ratio Slump value mm 1 Nil 2 34 3 100 B COMPRESSIVE TEST
