摘要： An improved block paving sand comprising kiln dried sand mixed with a water-soluble polymer. 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.

摘要： A paving material for filling gaps between paving blocks or the like, the paving material comprising a powdered or granulated mixture of: inert particulate; a water-soluble resin formable from a polymerisation reaction between formaldehyde and an at least difunctional nucleophile; and a water-soluble acid. The paving material is filled into gaps between blocks and then liquid water is applied thereto, or the sand is exposed to ambient humidity (gaseous water). Upon contact with the water, the resin coats the sand and then sets hard, thereby stabilising the block paving.
摘要翻译： 用于填充铺路砖等之间的间隙的铺路材料，所述铺路材料包括粉末状或粒状的混合物：惰性颗粒; 由甲醛和至少双官能亲核试剂之间的聚合反应可形成的水溶性树脂; 和水溶性酸。 将铺路材料填充到块之间的间隙中，然后将液体水施加到其上，或者将沙子暴露于环境湿度（气态水）。 与水接触时，树脂涂覆沙子，然后硬化，从而稳定块体铺筑。
