Therefore required water quantity = Cement Volume X WC Ratio = 0.282 X 0.55 = 0.1551 m 3 Unit weight of water = 1000 Litres / m 3

Get PriceSand is also used to create joints between each paver. Joint sand is usually polymeric sand that consists mostly of fine sand and silica. This creates a binding agent that solidifies the sand particles together, which helps lock all the pavers together. Harsh elements like wind and rain can break down the joint sand and cause it to erode over time.
