Robo sand & river sand is used as fine aggregate with specific gravity 2.51 & 2.59 respectively. The robo sand used in this research work was obtained from the stone quarry. 4) Cembinder: Cembinder used in this project is cembinder 17 manufactured by akzonoble. Containing Sio 2 40% by weight & specific gravity is 1.001, ph is 9.0
IS Code for Silt Content Test of Sand: IS 2386-2 (1963) Silt Content In Sand Limit. Silt content in the sand must not exceed 8% as per IS 2386-2. If the silt content on sand exceeds 8 % that may result in a reduction in the binding capacity of mixed materials, which also affects the strength and durability of the final product.

Sand & Tray; Test Procedure. First, we have to fill the measuring cylinder with 1% solution of salt and water up to 50 ml. Add sand to it until the level reaches 100 ml. Then fill the solution up to 150 ml level. Cover the cylinder and shake it well (as shown in video) After 3 hours, the silt content settled down over the sand layer
Robo sand is sand manufactured in stone quarries and it is a substitute for the river sand which is used in construction. Certain manufacturers are openly claiming that robo sand is a better alternative when compared to river sand. Listed below are few of the advantages of manufactured sand or robo sand:
The following tests may be performed to determine the quality of sand. Field Test To Check Sand Quality: 1. Take a glass and add some water in it. 2. Add a few amount of sand in the glass. At that point, shake it vivaciously and permit it to settle. If there is clay present in the sand, an apparent layer will be formed at the top level of sand. 3.

sand with robo sand or quarry dust at a water-cement ratio of 0.44. Results were matched with reference mix of 0% replacement. The compressive strength of cement concrete with 20%, 40%, 60% replacements were much more than that of reference mixes. According to price - service ratio the use of robo sand gives effective results; the cost of robo
5. Robo Sand (RS): Robo sand is the sand manufactured in the stone quarries. Robo Sand is collected from crushing unit.(ABM PLANT). Robo sand was used as a replacement material for fine aggregate in the current experiment.The test results of Robo sand is tabulated in table 5. Table 5: Test results of Robo sand Colour Off white
researchers have found a variety of alternatives to sand, one of which is quarry stone powder (artificial / robo / M-SAND). By using this robot sand with sand in various ratios, you can get the concrete mixture you need. The replacement of natural fine aggregate is done with 20%, 40% and 60%
In this present experimental study a comparative study has been carried out to check the usability of Robo sand in place of natural sand. This study involves determination of …

use of Robo sand because of its consistent gradation and zero impurity. The main objective of the present thesis was to systematically study the workability, strength of concrete with Robo sand and percentage replacement of Robo sand by river sand by 0%, 50%, 75%, and respectively. The study was carried out on
'River sand' has been used for concrete mason work, and requires very little water. River-sand or natural-sand has better texture, is smooth and round in shape with extremely low 'silt' and 'clay' content. 'Silt' is super fine material that is not good for construction. 'River sand' contains very less of silt making it an ideal raw material for construction.
2.2.2 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 4.75 mm sieve. The artificial sand is also tested to identify
Natural weathering of rocks results in the formation of river sand, over millions of years. Robo Sand (R.S) which is eco-pleasant serves as a partially substitute material for the depleting river sand. The addition of Robo sand can reduce construction cost and also increase the strength of the concrete. Rice husk is by-product from crop growing ...
