Ultrahigh-strength aeolian sand polymer concrete and preparation method thereof
The invention discloses ultrahigh-strength aeolian sand geopolymer concrete and a preparation method thereof. The concrete is prepared from, by mass, 40%-45% of industrial waste residues, 1%-3% of alkali activator raw materials, 10%-15% of fresh water, 40%-45% of aeolian sand and machine-made sand and 0.2%-0.5% of high-performance water reducing agents. According to the ultrahigh-strength geopolymer concrete, rich desert resources such as the aeolian sand are fully utilized, the slag, the fly ash and the silica fume are excited by the alkali activator to form a cementing material with a compact structure to prepare the ultrahigh-strength geopolymer concrete, and the local material utilization rate reaches 45-55%, so that the high cost generated by remote transportation of the river sand is reduced, and the service life of the concrete is prolonged. In addition, consumption of natural resources such as river sand and damage to the ecological environment in the river sand excavation process can be effectively relieved, and the requirement for high-strength structure engineering construction is expected to be met.
本发明公开了一种超高强风积沙地聚合物混凝土及其制备方法，混凝土包括质量百分比为40～45％的工业废渣，质量百分比为1～3％的碱激发剂原料，质量百分比为10％～15％的淡水，质量百分比为40～45％的风积沙和机制砂，质量百分比为0.2%～0.5%的高性能减水剂。本发明充分利用风积沙等丰富的沙漠资源，以碱激发剂激发矿渣、粉煤灰和硅灰形成结构致密的胶凝材料制备的超高强地聚合物混凝土，就地取材率达到45～55%，不仅减少了河沙远程运输产生的高昂代价，而且能够有效地缓解了河砂等自然资源的消耗以及河砂采掘过程中对生态环境的破坏，以期满足高强结构工程建设的需求。
