Description

一种节能环保空心砖及其制备方法
技术领域
本发明涉及建筑材料技术领域,更具体地说是一种节能环保空心砖及其制备方法。
背景技术
空心砖是以粘土、页岩等为主要原料,经过原料处理、成型、烧结制成。空心砖的孔洞总面积占其所在砖面积的百分率,称为空心砖的孔洞率,一般应在15%以上。空心砖和实心砖相比,可节省大量的土地用土和烧砖燃料,减轻运输重量;减轻制砖和砌筑时的劳动强度,加快施工进度;减轻建筑物自重,加高建筑层数,降低造价。
固体废物按来源大致可分为生活垃圾、一般工业固体废物和危险废物三种。此外,还有农业固体废物、建筑废料及弃土。固体废物如不加妥善收集、利用和处理处置将会污染大气、水体和土壤,危害人体健康。现有的固体废物处理方法简单,易对环境造成污染,如何变废为宝,降低其对环境的污染是急待解决的问题。
