Mortar is the bonding material between bricks, concrete block, stone, and many other masonry materials. It is made from Portland cement, lime, sand, and water in varying ratios. Each of the standard mortar mixes—Types N, M, S, and O—has different performance characteristics for …
River sand which is one of the basic ingredients the manufacture of concrete has become highly scarce and expensive. Hence, the crusher dust which is also known as Robosand can be used as an alternative material for the river sand. Robosand possess similar properties as that of river sand and hence accepted as a building material.

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. RoboSand TM is created by a rock-hit-rock crushing technique using state-of-the-art plant and machinery with world-class technology.
Jun 15, 2013· Robaxin contains methocarbamol, a muscle relaxant. It works by blocking nerve impulses (or pain sensations) that are sent to your brain. Robaxin is used together with rest and physical therapy to treat skeletal muscle conditions such as pain or injury.

M Sand is nothing but artificial sand made from crushing of rock or granite for construction purposes in cement or concrete. M sand differs from natural river sand in its physical and mineralogical properties. M Sand is a better substitute to rive...
Venu Malagavelli et. al. / International Journal of Engineering Science and Technology Vol. 2(10), 2010, 5107-5113 This paper presents the study of compressive strength and split tensile strength of M30 conventional concrete by replacing the 0 to 30% (5% increment) of sand with ROBO sand and 40 to 60% of cement with GGBS.
