The use of natural sand as fine aggregate in concrete is becoming problematic due to scarcity and pressure on mining of the resource. Alternate sources such as the use of industrial waste as replacement of natural sand in concrete are gaining popularity as a sustainable construction material.
The most commonly used fine aggregate across world is river sand. River sand is expensive due to excessive cost of transportation from natural sources. Also large scale depletion of the source creates environmental problems. As environmental, transportation and other constraints make the availability and use of river sand less attractive. A substitute or replacement product for concrete ...
Sawdust as partial replacement of fine aggregate in concrete materials and methods the binder used for this research was ordinary portland cement dangote brand. natural river sand of mm maximum size and crushed granite stone of 20 mm maximum size were used as fine and coarse aggregates respectively. clean tap water fit
Concrete of M25 grade was designed for a w/c ratio of for the replacement of 10% coarse aggregate with recycled coarse aggregate and replacement of 50, 60 and 70% of fine aggregate (sand ...
To improve the workability % of CeraChem plasticizer as admixture is M40 Grade concrete with manufactured sand was found to increase the compressive strength of concrete on all ages when compared to conventional concrete with river sand.
Suitability of Crushed granite fine (CGF) to replace river sand in concrete production was investigated Manaseeh Joel [2010] [5]. Slump, compressive and indirect tensile strength tests were performed on fresh a nd hardened concrete. Twenty eight days peak compressive and indirect tensile strength values of N/mm 2 and N/mm ...
The waste generation from granite stone industry is in the form of nonbiodegradable fine powder, the utilisation of this waste in concrete will help in sustainable and greener development. Published literature shows huge potential of granite dust as a replacement of natural fine aggregate.
Can we use msand (crusher sand) for concrete . Yes, MSand (crushed sand) can replace river sand in a concrete mix proportion. MSand are manufactured by latest technology (Vertical shaft impactor nachines). They give at par results in comparison to rivers sand concrete mixes, in both fresh and hardened state.

River sand (Fine aggregate), which is one of the constituents used in the production of concrete, has ...
The suitability of Crushed granite fine (CGF) to replace river sand in concrete production for use in rigid pavement was investigated. Slump, compressive and indirect tensile strength tests were performed on fresh and hardened days Peak compressive and indirect tensile strength values of /mm2 and /mm2 respectively was
Use of Crushed Granite Fine as Replacement to River Sand The suitability of Crushed granite fine (CGF) to replace river sand in concrete production for use in rigid pavement was investigated. Slump compressive and indirect tensile strength tests were
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 reduced and can also solve the problem of natural sand scarcity. The availability of sand at low cost as a fine aggregate in concrete is not suitable and ...

Slump, compressive and indirect tensile strength tests were performed on fresh and hardened days Peak compressive and indirect tensile strength values of /mm2 and /mm2 respectively was ...
Use of Crushed Granite Fine as Replacement to River . The analysis also revealed that the replacement of sand with more than 30% crushed granite fine will result in the production of concrete that is uneconomical when compared with the use of crushed granite and river sand as coarse and fine aggregate respectively.
Quarry Dust Fine Powder as Substitute for Ordinary Portland Cement in Concrete Mix 193 Journal of Engineering Science and Technology April 2014, Vol. 9(2) enhances compressive strength at hardened state [3]. However, there is still limited information on the behaviour of concrete properties with the inclusion of different
Feb 21, 2020· The superior shape and gradation of Poabs MSand ensures high strength concrete with significant savings in cement. MSand is crushed aggregates produced from hard granite stone which is cubically shaped with grounded edges, washed and graded with consistency to be used as a substitute of river sand.
River sand is nowadays a scarce commodity and exploring alternatives so an attempt is made on replacing the granite sludge powder as a partial replacement for fine aggregate in concrete the study is carried out with 20, 40, 60 and 80 percentage
They have found that it is possible to replace river sand partially in concrete (Prabhu et al., 2015, Siddique et al., 2009). This partial replacement also varies with respect to the physical and chemical properties of WFS which influence the characteristics of a concrete to .
Jun 02, 2016· Many studies have examined the influence of the partial replacement of fine aggregate in concrete using crusher dusts or small crushed sand samples on concrete properties [8,12,13]. However, little work has been performed on the complete replacement of natural fine aggregate in concrete with crusher dusts.
The reduction in the sources of natural sand and the requirement for reduction in the cost of concrete production has resulted in the increased need to identify substitute material to sand as fine aggregates in the production of concretes especially in Concrete. Quarry dust, a byproduct from the crushing process during quarrying activities is one of such materials. Granite fines or rock dust ...
Published literature shows huge potential of granite dust as a replacement of natural fine aggregate. The depletion of reserves of sand and stricter mining laws have made the need for substitution of natural sand in concrete an absolute necessity. A comprehensive overview of the published literature on the use of granite dust in concrete is ...
Yes As quarry dust(also called as crushed sand) is a byproduct obtained after crushing of stones(rocks) to make aggregates. * Results have shown that the concrete ...
