Abstract: An improved block paving sand comprising kiln dried sand mixed with a water-soluble polymer and hydraulic lime. The block paving sand is filled into gaps between blocks and then water is applied thereto. Upon contact with the water, the polymer coats the sand and then sets hard, thereby stabilising the block paving.
