Description

一种新型纳米增强免烧砌块
技术领域
本发明涉及一种新型纳米增强免烧砌块，具体涉及利用废弃粉煤灰来制备免烧砌块的方法。
背景技术
我国每年有大量的废弃粉煤灰，主要来源于电厂、矿区，近年粉煤灰只少量地用于肥料，更多的粉煤灰被废弃对环境造成了极大的破坏。但粉煤灰由于具有一定的活性人们尝试将其作为建材原料，但性能欠佳。而将粉煤灰制备成免烧砌块不但能够减轻环境的负担，同时也变废为宝、节约自然资源，同时由其制成的产品性能优良韧性好、保温、隔热。
发明内容
本发明的目的是提供了一种纳米增强免烧砌块，工艺简单，对固体废弃物利用率高，所述免烧砌块重量轻、强度较好、耐久性好，对能源消耗较小对环境无污染。
本发明技术方案为：原料（按重量比计）采用水泥22份、粉煤灰50份、河砂或石英砂10份、木质素磺酸盐0.3份、氢氧化钠3份、秸秆和/或稻壳9份、纤维素醚5份和水15份、矿渣10份、胶粉0.05份、早强剂1份，所述胶粉由以下原料混合而得：纳米碳酸钠5重量份、纳米碳酸钙10重量份、五水偏硅酸钠25重量份；所述粉煤灰为二级粉煤灰。本发明所述免烧砌块可采用公知的现有技术进行制备。
本发明的有益技术效果：
本发明对固体废弃物能够充分利用，所述免烧砌块重量轻、强度较好、韧性及耐久性好，对能源消耗较小对环境无污染。
具体实施方式
原料（按重量比计）采用水泥22份、粉煤灰50份、河砂或石英砂10份、木质素磺酸盐0.3份、氢氧化钠3份、秸秆和/或稻壳9份、纤维素醚5份和水15份、矿渣10份、胶粉0.05份、早强剂1份，所述胶粉由以下原料混合而得：纳米碳酸钠5重量份、纳米碳酸钙10重量份、五水偏硅酸钠25重量份；所述粉煤灰为二级粉煤灰。
