钢纤维增强水泥墙板及其制备方法。现有的墙体材料有重量大,价格贵,有些材料有毒性等不足。用短切该纤维增强水泥制备墙板材料,采用普通水泥、无机轻质材料,钢纤维,促凝剂等合理组分,经搅拌、泵挤、成型、吸水、抽芯等工序,即可制成轻质、节能、强度高的墙板。
Steel fiber reinforced cement wallboard and its preparation method. The existing wall materials have large weight, expensive price, and some materials are toxic and so on. A short cut fiber reinforced cement is used to prepare wallboard material. Ordinary cement, inorganic lightweight material, steel fiber, coagulant and other reasonable components are used to make lightweight, energy saving and high strength wallboard by mixing, pump extrusion, molding, water absorption and core pulling process.
专家解析钢纤维超高强混凝土(FSFRUHSC)是在高强度等级的混凝土基体中掺入乱向分布的钢纤维所形成的新型复合材料,其抗压强度超过100MPa.FSFRUHSC具有较好的抗压性能和优良的抗侵彻、抗爆炸性能,能够应用在军事工程尤其是新型核爆洞安全防护层等一些特种工程结构中。由于应用FSFRUHSC的时间相对较短,因而对不同尺寸FSFRUHSC试件的抗压强度及其压缩破坏模式等抗压性能有待进一步探讨。
Expert analysis of steel fiber reinforced ultra high strength concrete (FSFRUHSC) is the incorporation of new composite chaos to the distribution of steel fiber in concrete matrix formed by high strength concrete, its compressive strength more than 100MPa.FSFRUHSC has better compression performance and excellent anti penetration and anti explosion performance, can be used in military engineering especially new nuclear explosion the hole of protective layers and some special engineering structure. Due to the relatively short time of FSFRUHSC application, the compressive strength and compression failure mode of FSFRUHSC specimens with different sizes should be further explored.
目前已经对普通钢棉纤维混凝土以及低含量钢棉纤维高强混凝土的单轴或三轴压缩性能进行了一系列试验,但对钢棉纤维混凝土损伤变形特性的研究还相对较少,特别是对于钢棉纤维混凝土含量在一定范围内波动时,钢棉纤维的几何尺寸对钢棉纤维混凝土增强和增韧效果及损伤变形特性的研究还比较少见。
Now the ordinary steel fiber concrete and uniaxial low content of steel fiber high strength concrete or three axial compression performance of a series of tests, but the study on the deformation properties of steel fiber concrete damage is relatively small, especially for the content of steel fiber concrete in a certain range, the geometric size of steel wool fiber on steel fiber reinforced concrete and Study on the toughening effect and damage deformation characteristics are still relatively rare.
