磨细矿粉对轻骨料混凝土耐久性能影响的研究

Influence of superfine gangue powder on durability of lightweight aggregate concrete

通过磨细矿粉对轻骨料混凝土耐久性能影响的试验研究,重点探讨了磨细矿粉对轻骨料混凝土的抗冻性能、抗渗性能、抗碳化性能、干缩性能的影响。研究结果表明:轻骨料混凝土中掺加磨细矿粉可大幅度提高其抗渗透性能,增强混凝土的抗冻融能力,改善其抗碳化性能,但混凝土的收缩率提高。

Influence of superfine gangue powder on durability of lightweight aggregate concrete is studied by experiments; mainly discussed in- fluence of superfine gangue powder on frost resistance, impermeability, performance-carbonation and dry shrinkage of light aggregate concrete. The result shows that,adding superfine gangue powder in lightweight aggregate concrete can greatly improve its impermeability and frost resistance.But shrinkage ratio of the concrete will rise.
