第二是碎石。从山上的料厂破碎后运到施工工厂，如果抓一把，手上会沾很多石粉。"十四五"期间我国推广水 洗法，先进的工地已经推广了超声波清洗法，这样石子经过清洗之后，颗颗都像饱满的粮食一样，非常可 爱。 第三是混凝土。我国公路工程70%左右是混凝土工程，大家对混凝土非常重视。现在逐渐推广钢模板，有的地 方推广了不锈钢模板，更有条件的地方推广抛光的不锈钢模板，去这种工地会有一种幻觉，觉得像站在哈哈 镜的面前一样，一面面镜子放在那里，混凝土经过脱模之后，都可以照见人的影子。 21世纪经济报道记者 周潇枭 北京报道 5月29日，国务院新闻办举行"新征程上的奋斗者"中外记者见面会，邀 请五位来自交通运输领域的代表，围绕"加快建设交通强国 勇当开路先锋"主题与大家交流。 交通运输部公路科学研究院基础研究创新中心副主任田波作为交通领域代表之一在发布会上表示，"十四五"是 我国公路建设的大发展时期，公路由普通转向品质工程。我国水泥混凝土如何做出高品质，实际和做美食一 样，要有很好的食材，水泥混凝土最核心就是砂子、碎石、水泥。 首先是砂子。因为环保的要求很严，从河里取砂子受到限制，便逐渐转向了人工砂，就是把碎石经过逐级破 碎、拆 ...
