Robo Sand RS Robo Sand RS is obtained in wet form directly taken from deposits of Crushed stone factories Wet Robo Sand was dried before the sample preparation Robo Sand contains several crushed stones Hence Robo Sand is sieved through mm sieve The artificial sand is also tested to identify
Additionally using Robo Sand in concrete and masonry results in the substantial saving of cement thus slashing construction costs considerably Robo Silicon now has a range of construction materials that are collectively referred to as Robo Aggregates fine and coarse aggregates that confirm to IS 383 specifications
Robo sand Tests were conducted on cubes cylinders and beams to study the strength of concrete by using Robo sand and the results were compared with the Natural Sand Concrete During the present study 0% 25% 50% 75% and 100% of traditional fine aggregate was replaced with Robo sand Compression split and flexural
grade concrete made of both Natural sand and Robo sand and the results were compared for drawing a conclusion Methodology and experimental work involves the tests required to ascertain the quality of materials for tests results on Ordinary Portland cement are shown in Table 1 Table 1 Physical properties of Ordinary Portland cement of 53
Most popular and widely used building material is concrete in the field of construction It was found suitable than any other materials and hence very important for the constructional developments The consumption of the concrete is huge and
It was also found that at the percentage replacement of cement by carbon black 5% and robo sand by natural sand 50% the concrete becomes denser as both carbon black and stone dust act as
3 Importance of Sand Bulkage Test If we need 1 m 3 of sand in concrete we need to know the approximate sand bulkage value Say for example sample sand that we are going to use has 30% bulkage of sand then we need to take 30% more sand that is times of sand while volume batching in order to get 1 m 3 of sand for concrete
Advantages of Robo Sand 1 Consistency in Quality One of the primary benefits of robo sand is its consistency Unlike natural sand which can vary in particle size and quality robo sand is produced under controlled conditions This results in a uniform product that enhances the reliability of construction mixes
Robo sand is an alternative to river sand that is manufactured through a rock crushing process using advanced machinery It has several advantages over river sand including a more uniform particle shape and size that results in higher compressive strength and durability for structures Robo sand also has fewer impurities requires less cement
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
Robo sand Robo Sand is derived by crushing stones in a quarry to obtain the desired granular material The sand used in concrete must have a proper gradation of 150 microns to mm The fineness modulus of Robo sand is The uniformity coefficient is less than 6and its specific gravity is Pic 1Robo sand Pic 2 carbon black
The Robo Sand as used in the building and construction industry is synonymous with fine aggregate which is the material with a particle size less than 5mm Coarse sand is Characteristics Test Results Requirements as per IS 12269 1987 1 Fineness retained on 90 µm sieve 6% <10% 2 Normal Consistency 33% 3 Initial setting time of
Robo Sand he study the strength of concrete has been evaluated by replacing natural or river sand with Robo sand at various proportions 0% 25% 50% 75% and 100% for M40 grade of concrete with water cement ratio of From the test results it has been observed that the Split tensile strength of M20 and M25 grade concrete
Finally it was observed that the specimens with combination of GGBFS and ROBO sand for 40% had the optimum compressive strength and resistance against sulphate acid attack as a result it can be
Advantages of Robo Sand 1 Consistency in Quality One of the primary benefits of robo sand is its consistency Unlike natural sand which can vary in particle size and quality robo sand is produced under controlled conditions This results in a uniform product that enhances the reliability of construction mixes
