在人们眼里，古水磨石总是被贴上"土丑"的标签。

它是将碎石、玻璃、石英石等材料与水泥粘结剂混合，然后研磨抛光的产品。

记忆里，水磨石大多被应用于学校、医院等大型建筑，虽然施工方便、造价低廉又很耐磨，但总是给人一种很low的感觉。

自20世纪90年代以来，水磨石逐渐退出历史舞台，被其他更具优势的新材料所取代，长期沉默。

In people's eyes, ancient terrazzo is always labeled as "dirt ugly".
It is a product that mixes gravel, glass, quartz and other materials with cement binder, and then grinds and polishes.
In my memory, terrazzo is mostly used in schools, hospitals and other large buildings. Although it is convenient for construction, low cost and wear-resistant, it always gives people a very low feeling.
Since the 1990s, terrazzo has gradually withdrawn from the historical stage and been replaced by other more advantageous new materials, which has been silent for a long time.
