摘要

摘要:本文的目的是建立一个框架,以管理由采石场砂砂浆轮胎橡胶增值废物产生的废物。为实现上述主要目标,开发了一种研究方法。为生产采石场砂砂浆中使用的橡胶屑创建一个框架,具有足够的物理和机械性能,可用于各种建筑应用。测试包括强度和导热性能的各种混合物组成受到变化5%。10%。15%和20%由采石场砂替代。采用扫描电子显微镜和能谱仪(SEM/EDS)研究了混合砂浆的内部微观结构和物相组成。结果表明,增加添加剂掺入率可显著改善基材的热物理性能,并对所制砂浆的硬化性能进行了分析和比较,实验结果表明:在采石砂砂浆中加入橡胶废屑有利于其物理性能(Mv)质量损失,所研究的橡胶基采石砂浆的力学强度也明显降低。在基质中加入5% ~ 20%的橡胶屑和在砂浆中用20%的橡胶代替砂石,记录了低导热性能,包括适当的QS和CR水平可以改变砂石砂浆的模式。更大的孔隙率和更高的孔隙率会产生一个不那么坚硬和均匀的矩阵,这意味着声波脉冲必须通过更长的和更复杂的路径,这改善了绝缘。新材料的良好性能促使我们将其融入建筑围护结构中。

Rubber Influence on the Performance of Thermal Insulating Quarry Sand Mortars-A Statistical Analysis
Abstract The purpose of this paper is to develop a framework for managing wastes resulting from the tire rubber valorization waste of quarry sand mortar. A research methodology was developed to achieve the abovementioned main objective. To create a framework for use of crumb rubber in the production of quarry sand mortars, with adequate physical and mechanical properties to be used in a variety of construction applications. Testing included strength and thermal conductivity properties of the various mixture composition subjected to varying by 5%. 10%. 15% and 20% by quarry sand substitution. The internal microstructure, and phase composition of all mixture mortars, were investigated using scanning electron microscopy and energy-dispersive X-ray spectroscopy (SEM/EDS). The results show that increasing incorporation rate of additives significantly improves thermophysical properties of based materials, the hardened properties of the various mortars made are analyzed and compared, the experimental results revealed that; the addition of crumb rubber waste in the quarry sand mortar is beneficial for physical properties (Mv) mass loss, The results of mechanics strength of the rubber based quarry mortar studied are also significantly reduced.The addition of 5% to 20% rubber crumb in matrix and the replacement of sand by 20% of rubber in quarry mortar record the low thermal conductivity properties including that appropriate QS and CR levels may change the pattern of quarry sand mortar. witch explain by a Larger pore and higher porosity produce a less rigid and uniform matrix, meaning that the sonic pulses must travel through longer and more miscellaneous paths which improvement of insulation. The good performance of new materials encourages us to integrate them into the building envelope.
