当前,建筑材料的发展非常迅速,出现了很多新材料,陶粒混凝土空心砌块便是其中的一种,陶粒混凝土空心砌块在外围护墙体砌筑中使用比较普遍,特别是寒冷地区,因为陶粒混凝土空心砌块中的粗骨料陶粒,属于轻骨料中的一种,由它制成的砌块也因此有轻质的优点,并且陶粒混凝土和水泥产生水化反应时,会产生很多封闭或者处于半封闭状态的孔隙,延长了热传递的路线,因此保温隔热效果好、陶粒轻骨料制成的砌块表观密度较同类产品小、但是强度较高。这种材料的缺点主要表现在砌成后的墙体容易开裂,其中有些墙体不仅仅是抹灰层开裂,甚至有些裂缝深度可以使陶粒混凝土砌块本身开裂,形成墙体内外的通透裂缝。设计和施工时要特别注意,防止采用这种砌块砌成的墙体产生裂缝。
At present, the development of building materials is very rapid, there are a lot of new materials, hollow ceramic block is one of them, ceramsite concrete hollow block masonry building in the outer wall is more common, especially in cold areas , Because coarse aggregate ceramsite in ceramsite concrete hollow block belongs to a kind of light aggregate, so the block made from it also has the advantages of light weight, and the ceramsite concrete and cement produce hydration reaction , It will produce a lot of closed or semi-closed pores, extending the heat transfer route, so the thermal insulation effect is good, the apparent density of lightweight blocks made of ceramsite lighter than similar products, but the higher the intensity . The shortcomings of this material mainly in the wall after cracking is easy to crack, in which some walls not only cracking the plaster layer, and even some cracks depth can make concrete block itself cracking ceramsite, the formation of the wall inside and outside the transparent crack. Design and construction should pay special attention to prevent the use of such blocks brick wall cracks.
