高强发泡水泥轻质墙板和轻质混凝土填充与保温工程中的应用

发布时间:2018/10/16 10:43:04 浏览次数:143

高强发泡水泥轻质墙板不光具有耐水、不燃、抗冲击、收缩小等长处,并且安装施工利便,能刨、锯、钉等,不抹墙皮,外表可直高强发泡水泥轻质墙板。这种高强发泡水泥轻质墙板的主要原料为工业废渣粉煤灰、水泥、钢丝网及其他化工原料,其强度可以到达25号砖的水平。出产过程经特别工艺将充气发泡技能使用于水泥中,在不影响水泥强度的情况下,内部空心率能到达50%以上,然后到达保温隔音的作用,一起由于利用了很多的粉煤灰,不光具有可观的经济效益,比运用粘土砖、空心砖工程造价下降约20%,并且还确有很好的社会效益和环境效益。

  跟着经济建设迅猛开展,轻质混凝土市场需求日益增长,轻质混凝土的开发和使用意味着节能、节约资源、下降修建造价。因此,开展高性能轻质混凝土含义严重。 80年代,澳大利亚开发了BST专利技能,将胀大聚苯乙烯泡沫珠进行外表化学处理,取得均质、性能较好的轻质混凝土,用于修建工程。我国是一个混凝土大国,但轻质混凝土欠开展。香港区域选用过BST技能出产轻质混凝土;北京、深圳、上海、广州等地均有选用经破碎炸毁加工成粒后的废旧聚苯乙烯泡沫塑料(或EPS泡沫珠)配制成的轻质砂浆或混凝土,试用于屋面保温隔热、外墙外保温工程、墙体芯材等。 20世纪50年代,法国、德国就开发了EPS泡沫珠混凝土,用于保温隔热工程、路途保温维护等范畴。

High strength foamed cement lightweight wallboard not only has the advantages of water resistance, non-flammable, impact resistance, small shrinkage, and easy installation and construction, can be planed, saw, nail, etc., without plastering wallboard, the appearance of high strength foamed cement lightweight wallboard. The main raw materials of this high strength foamed cement lightweight wallboard are industrial waste slag fly ash, cement, steel wire mesh and other chemical raw materials. Its strength can reach the level of No. 25 brick. In the production process, the aerated foaming technology is used in cement by special technology. Without affecting the cement strength, the hollow rate can reach more than 50%, and then reach the function of insulation and sound insulation. Because of the use of a lot of fly ash, not only has considerable economic benefits, but also reduces the construction cost by about 20% compared with the use of clay bricks and hollow bricks. It also has good social and environmental benefits.

With the rapid development of economic construction, the demand of light concrete market is growing day by day. The development and use of light concrete means energy saving, resource saving and construction cost reduction. Therefore, the development of high-performance lightweight concrete is of great significance. In 80s, Australia developed the BST patent technology, which made the swell polystyrene foam bead surface chemically treated, obtaining homogeneous and better lightweight concrete for construction. China is a large country of concrete, but lightweight concrete has not been developed. Hongkong area has used BST technology to produce lightweight concrete. In Beijing, Shenzhen, Shanghai, Guangzhou and other places, lightweight mortar or concrete made of crushed polystyrene foam (or EPS foam beads) after crushing and explosion processing has been selected for trial use in roofing insulation, external wall insulation projects, wall core materials, etc. In 1950s, France and Germany developed EPS foam bead concrete for insulation and heat preservation.
