Modified limestone powder for manufacturing concrete
The invention relates to the field of concrete, in particular to modified limestone powder for manufacturing concrete. The modified limestone powder is prepared from limestone powder, absolute ethyl alcohol, lecithin, water glass, polyvinyl alcohol, and hollow glass beads at the mass ratio of (30-40): (50-60): (1-2): (3-4): (2-3): (5-7). The modified limestone powder prepared by the invention is used for preparing concrete, has high mechanical strength, can effectively improve the sulfate corrosion resistance of limestone powder concrete, and has a remarkable improvement effect on the limestone powder concrete in a tunnel in a high water pressure and sulfate corrosion environment.
本发明涉及混凝土领域，特别涉及一种用于制作混凝土的改性石灰石粉；由质量比为(30～40):(50～60):(1～2):(3～4):(2～3)：(5～7)的石灰石粉、无水乙醇、卵磷脂、水玻璃、聚乙烯醇和空心玻璃微珠组成。本发明制备出来的改性石灰石粉用于制备混凝土，力学强度高，可有效地提高石灰石粉混凝土的抗硫酸盐侵蚀性能，对隧道中石灰石粉混凝土在高水压、硫酸盐侵蚀环境下起到显著改善作用。
