炉渣对轻集料混凝土复合保温砌块性能的影响
|
摘要
采用当地主要原材料掺加复合外加剂进行正交实验,依据相关标准测试了炉渣作为主要成分的轻集料混凝土的主要性能,将试验结果与检测机构出具的检测结果进行对比分析,结果表明:试验数据与检测数据符合度较好,即炉渣应用于轻集料混凝土制作的复合保温砌块,不仅具有良好的物理力学性能,还具有相当好的热工性能。另一方面,由于复合保温砌块的主要成分为经过粉碎筛分的炉渣粉和粗炉渣,因此,固体废弃物的循环利用不仅降低了产品成本,还对厂矿企业周边起到了环境保护的作用。
Adopted the main local raw material and compound admixtures to conduct orthogonal test and evaluated the main performance of light aggregate concrete, in which the slag played the main role, according to relevant standard. The conclusion were obtained by comparing the experimental results and testing value from testing organization, which indicated that the experimental results correspond to the testing value. On the one hand, the composite thermal-insulating block that applying slag powder to light aggregate concrete had not only good physical and mechanical properties, but also great thermal performance. On the other hand, the main components of composite thermal-insulating block were slag powder and coarse slag which had been grinded and sieved. Therefore, cyclic utilization of solid waste can not only reduce construction cost, but also protect the environment around the industrial and mining enterprises.
