The present paper focuses on investigating characteristics of M30 concrete with partial replacement of cement with
Ground Granulated Blastfurnace Slag and sand with the ROBO sand (crusher dust). The cubes and cylinders are tested for both compressive and tensile strengths. It is found that by the partial replacement of cement with GGBS and sand with ROBO sand helped in improving the strength of the concrete substantially compared to normal mix concrete.

The crusher dust produced from granite crushers is one of the alternative materials for river sand. The utilization of
crusher dust which can be called as ROBO sand has been accepted as a building material in the western countries. Lot of research has been done regarding the crusher dust as alternative materials for river sand. Misra studied the effect of complete replacement of sand by stone dust in the cement. 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/m 3. 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 represents the grain size distribution of ROBO sand.

Robo Sand Project Report Pdf in Bangalore Karnataka India
Attempt is being made to develop eco-friendly and economically viable process routes to extract the metal values from the sea nodules. Injection metallurgy is predominantly used in the industry to decrease the impurity content of liquid steel ferro-alloys in a more economical way. Detailed study on design and operating parameters for such high temperature processes is an important issue, and is being studied in the laboratory through physical modeling. Direct reduction of iron ore using mine generated ore and coal fines, is one of the major research areas where the work has been initiated with MHRD project. One of the present research interests also includes the mathematical modeling of fluid flow and heat transfer during welding. Optimization of various design and operating parameters during fusion welding, mathematical modeling of heat transfer during pulsed laser welding that results in low distortion and which has ability to weld heat sensitive components, are also present areas of research in the area of extractive metallurgy.
