张:老李同志,请你给介绍一些有关新型建筑材料的知识可以吗?李:可以!可以!张:那就请你先说说什么是新型建筑材料?李:所谓新型建筑材料,是指那些新近研制成功的建筑材料,是同那些传统的粘土砖瓦比较而言的.张:有些人把石膏板,加气混凝土,矿棉和石棉水泥板等称为新型建筑材料,你说对不对呢?李:石膏板、加气混凝土、矿棉和石棉水泥板等,同我们大量使用的,有两千多年历史的“秦砖”“汉瓦”相比,可以说是新型建筑材料.不过在国外已经有多年的生产历史,算不了什么新东西了.
Zhang: Comrade Lao Li, could you please give us some knowledge about new construction materials? Li: Yes! Yes! Zhang: Then please talk about what is new building materials? Lee: The so-called new building materials mean The newly developed building materials are compared with those of traditional clay bricks. Zhang: Some people call gypsum board, aerated concrete, mineral wool, and asbestos cement board as new building materials. You are right? Li: Gypsum board, aerated concrete, mineral wool, and asbestos cement board, etc., can be said to be new types of construction materials compared to the large number of “Qin bricks” and “Hanwa” that have been used extensively for more than 2,000 years. However, there have been many years of production history in foreign countries and nothing new can be considered.
