Silica) As Fine Aggregate Vishnumanohar.A Assistant professor Dept. of Civil engineering Sahrdaya College of engg. Tech Kodakara,Thrissur. ABSTRACT : Concrete is the most undisputable and indispensable material being used in infrastructure development throughout the world. Umpteen varieties of concretes (FAC, HVFAC, FRC, HPC, HSC, and others) were researched in several laboratories and
Aggregates- Sand is the fine aggregate. Gravel or crushed stone is the coarse aggregate in most mixes. Desired Properties of Concrete. 1. The concrete mix is workable. It can be placed and consolidated properly by yourself or your workmen. 2. Desired qualities of the hardened concrete are met: for example, resistance to freezing and thawing and deicing chemicals, watertightness (low
Concrete containing quarry dust as fine aggregate can be effectively utilized in the construction industry with good quality materials, appropriate dosage of super plasticizer, appropriate mixing methods, and proper curing thereby ensuring sustainable development against environmental pollution (Devi and Kannan ). The study of Ilangovana et al gives attention to physical and chemical
Therefore, granite fines can be effectively used as a replacement material for fine aggregate in concrete. For investigation purpose cubes are casted with 7 different proportions of granite fines and fine aggregate. The replacement percentage of granite fines to fine aggregate are 0, 10, 20, 30, 40, 50 and 100 for M20 mix proportions, specimens are tested after 28 days of curing, for
Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar. Types of aggregates include Coarse aggregate and fine aggregate. The aggregate of each type is further sub-divided into many types and classification based on its size. The technique of
Use of Quarry Dust to Replace Sand in Concrete – An times the cost for crusher waste even in places where river sand is available nearby. The function of the . Get Price . What are the advantages of using quarry dust as fine . May 23, 2017 The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust
Coarse aggregate, Fine aggregate – Natural sand (IS383-1970). 3.2 Silica Sand Silica sand is a by-product obtained from cement manufacturing process. Silica sand is fine powder which can replace up to a different percentage of conventional sand usage in concrete. Its
Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate. When determining the strength of normal concrete, most concrete aggregates are several times stronger than the other components in concrete and therefore not a
Feb 04 2015 New type of crushed sand to replace natural sand in concrete production The availability of natural sand for concrete production is facing challenges while the socalled waste stockpiles at aggregate crushing areas are causing problems for producers .

14.09.2018Waste tire rubber can be incorporated in self-compacting concrete by partially replacing the natural fine and coarse aggregate, reducing consumption of sand and gravel and preserving these natural materials. In addition, recycling and reusing waste tire rubber avoids the need for tire landfilling, as one of the major ecological problem of the near future. Replacement of natural aggregate with
been made to use this waste material in the concrete to replace fine aggregate . In this study experimental investigations were performed to evaluate the properties of fresh and hardened concrete containing waste foundry sand as fine aggregate replacement. Fine aggregate were replaced partially and fully with waste foundry sand. The percentages of replacement 0%, 20%, 40%, 60%, 80%,
iv) In its purest form the bagasse ash can prove to be a potential ingredient of concrete since it can be an effective replacement to cement and fine aggregate.

Abstract: Fine aggregate can be extracted from waste concrete by series of processing. The recycled fine aggregate can then be utilized to manufacture recycled fine aggregate mortar (RFAM) or recycled fine aggregate concrete (RFAC). Air entraining agent was added in RFAM to improve its mechanical performance. The influence of the dosage of the
the concrete composition can also be suitable for partial replacement (up to 60%). the fly ash, quarry rock dust can be used form 20% replacement of cement and fine aggregate in concrete. it was concentrated to avoid environmental degradation due to industrial wastes form cement factories.

Disadvantages Of Crushed Sand In Concrete . New type of crushed sand to replace natural sand in, Another approach involves finding ways to make crushed sand perform as well or better than natural sand by utilizing its intrinsic properti This also includes developing a new concrete mix design philosophy that is adapted to crushed sands with specially engineered properties that are.
CONCLUSIONS The development of concrete with glass powder as fine aggregate has been successfully completed and the results were presented and analyzed in the previous chapters. Based on the test results of M50 concrete the following conclusions are drawn: A. General Conclusions 1) It is possible to replace glass powder by scarce sand for

F.M of Ideal fine aggregate for concrete applications are in range of 2.6 to 2.9. Fine sand (lower F.M Value ) reduces the sand requirement % in the total aggregate proportion. On the other hand, coarser sand will require higher sand % in the total aggregate proportion to give a cohesive concrete mix consuming least cement. Any material which are basically chemically inert and having particle
In this study the properties of concrete with quarry dust as fine aggregate is studied to find out its suitability to replace river sand in structural concrete. Furthermore, use of fly ash with 30% of cement replaced by fly ash is explored as means of increasing the performance of the quarry dust mixes. Quarry dust concrete at the tested water cement ratio is found to have higher compressive
waste tyre crumb rubber particles was used to replace fine aggregate in concrete of size passing through 1.18 mm IS sieve and retaining on 600 IS sieve at ratios 0.5 %,1%,1.5%, 2%, and also in combination with glass fiber at ratios 0.4 %, 0.5% addition to
Depending on the mix design, either can be used to make essentially any range of concrete strengths. When you use a smaller aggregate, such as the 10mm as your nominal coarse aggregate size, the specific surface area of the total volume of coarse aggregate is much higher than for the 20mm aggregate.
