500mm gasoline concrete cutter good quality from factory

A concrete saw (often known as a consaw or road saw) is a power tool used for cutting concrete, masonry, brick, asphalt, tile, and other solid materials. It can be a small hand-held cut-off saw, a big walk-behind saw or other styles, and it may be powered by gasoline, hydraulic or pneumatic pressure, or electric motors. The saw blades used on concrete saws are often diamond saw blades to cut concrete, asphalt, stone, etc. Abrasive cut-off wheels can also be used on cut-off saws to cut stone and steel. The significant friction generated in cutting hard substances like concrete usually requires the blades to be cooled to prolong their life and reduce dust.

Without planned joints, new pavement will experience random cracking within the first

72 hours of life. This random cracking is aesthetically undesirable and can be detrimental to the long-term durability of the pavement. Joints are cut to control random cracking, accommodate slab movements,ensure joint locations match load transfer device placements, and divide the pavement into practical construction elements. Cuts sawed into the surface of hardening concrete form a line of weakness, causing the concrete

to crack below the sawcut instead of cracking randomly.
