Instead of disposing them in landfills, it can be best utilized as partial replacement to sand. In crusher dust, the particles (% finer than 150 microns) are generally high, a major concern limiting its percentage replacement to minimum with sand in a concrete mix. It can be replaced to the amount 25%. Its Availability is not a concern.
Replacement of fine aggregate with robo sand by and also finding the compressive Strength of that concrete cube. In This Project presents are view of the different alternatives to sand in preparation of concrete. this present experimental study a comparative study has been carried out to check the usability of robo sand in place of fine aggregate.
ROBO sand: ROBO sand or crusher dust obtained from local granite crushers was used in concrete to cast the cubes and cylinders. The bulk density of ROBO sand or crusher dust is 1768 kg/m3. The specific gravity and fineness modulus of ROBO sand are 2.66 and 2.88 respectively. Sieve analysis results are shown in Fig. No. 2
The tensile strength of the concrete also increases, if the replacement of fine aggregate is up to a certain percentage. Hence, one can replace the river sand up to 25%-50% in the concrete mixes. This type of replacement has a lot of advantages to the environment as well as human kind.

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 ...
Yes, M-Sand (crushed sand) can replace 100% river sand in a concrete mix proportion. M-Sand 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. Since quality control is maintained in the process of preparing manufactured sand, the …
Hi All, I am planning to construct a house in my native(Tamil Nadu) so i did a survey by visiting few construction sites who are using M-sand. since the supply of ...
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.
In this research, M-25 grade concrete was produced from geopolymer fly ash sand (GFS) manufactured using fly ash and an alkaline activator solution as an alternative material to the natural river sand (NRS). The alkaline activator with 4 Molar NaOH solution and Na2SiO3/NaOH = …
Effects of Robo sand replacing. river sand in concrete. PRESENTATION BY. N Saikrishna. P Rakesh. Sumair. Sabir ali. Salman ABSTRACT: Concrete is the most widely used composite construction material. Fine aggregate plays a very important role in concrete. Generally, river sand was used as fine aggregate in concrete. In this project ,we are going to replace the river sand with ROBO SAND.
In the present investigation workability, strength and durability of concrete with manufactured sand as replacement to natural sand in proportions of 0%, 20%, 40%, 60% and 100% is studied.
replacement by weight of cement and sand at 0%, 10%, 20%, 30%, and 40%. Fresh concrete tests and hardened concrete tests like compressive strength test, split tensile strength and flexural strength was carried out. Result shows that 20% replacement of eco sand and 30% replacement of GGBS gives optimum strength.
A GREEN REVOLUTION FOR FUTURE CONSTRUCTION. Robo Silicon, for the first time in India, introduced “Manufactured Sand” as a viable, cost-effective and an eco-friendly alternative to the precious and fast depleting natural resource -river sand.. Robo Silicon is the first company to brand its sand as “ROBOSAND TM ”.It is manufactured just the way nature has done for over a million years.
Manufactured sand is sand produced by crushing rocks, quarry stones or larger aggregates pieces into sand-sized particles. Natural sand, on the other hand is. ... Nearly 65-80% of the volume of concrete and screed mixes is made up of sand/aggregates. ... It can be used as a replacement or as a blended mixture with natural sand.
Higher concrete strength compared to river sand used for concreting. Lesser concrete compared to M Sand. Silt Content. Zero silt. Minimum permissible silt content is 3%. Anything more than 3% is harmful to the concrete durability. We can expect 5 - 20% slit content in medium quality river sand. Over Sized Materials. 0%. Since it is artificially ...
Researchers at the University of Bath and Goa Engineering College in India have successfully demonstrated that replacing just 10 percent of the sand in concrete with …

Researchers from the Deakin School of Engineering have discovered that recycled or waste glass can substitute sand when making polymer concrete, a material often used in the construction industry.. Polymer concrete is a type of concrete that uses polymers, typically resins, to replace lime-type cements as a binder. This produces a high-strength, water-resistant material suited to industrial ...
In recent days there were also been many attempts to use Fly Ash, an industrial by product as partial replacement for cement to have higher workability, long term strength and to make the concrete more economically available. This present work is an attempt to use Quarry Dust as partial replacement for Sand in concrete.
Concrete is the most widely used construction material in the world it is a mixture of cement, sand, coarse aggregate and water. Storage and safe disposal of industrial byproduct such as Waste foundry sand is major disposable item of metal casting industries and plastic bottle is a huge problem everywhere, reuse of these waste eliminates reduce the problem.
Scarcity of sand and environmental hazards caused due to the depletion of sand has led to the discovery of new materials for its replacement. Many materials have been discovered to replace sand and have yielded positive results. Glass is one such
Rui V. Silva, Jorge de Brito, in Waste and Supplementary Cementitious Materials in Concrete, 2018. 7.4.4.2 Carbonation. Akçaözoglu et al. (2010) evaluated the effects of using PET aggregates as sand replacement in the production of mortars. The results suggest that the incorporation of 100% PWA as sand replacement led to greater resistance to carbonation when compared with mixes containing ...
01-02-2017· Nowadays it is very important to make the concrete economical. Therefore the present work has initiated to make the concrete economical by replacing the natural sand by crushed sand in the concrete. From our study it is concluded that different Crushed sand gives different results for compressive strength depending on different quarries and from study of different research paper at …
Sustainability of Concrete Using Copper Slag as Replacement for River Sand Concrete consumption is so extensive that it stands second to water. Spiraling urbanization has led to excessive consumption of concrete, which has increased the demand for sand, cement and coarse aggregates.
