粉煤灰作为混凝土组成的主要掺加材料,其质量的好坏对混凝土性能有一定的影响。粉煤灰的组成和化学成分对粉煤灰在混凝土中三大效应的发挥有直接的影响,只有充分保证粉煤灰的原材料质量的稳定性,才能最大限度地发挥粉煤灰对混凝土的性能改善的积极作用。而现在市场上存在真假粉煤灰、脱硫灰、脱硝灰、浮黑灰等,严重影响了混凝土的工作性能、力学性能和耐久性能。如何辨别粉煤灰质量的好坏?买到质量差的粉煤灰应该如何处理?第7期特别策划邀请大家各抒己见。
Fly ash as a main component of concrete admixture, the quality of concrete has a certain impact on the performance. The composition and chemical composition of fly ash have a direct impact on the effect of fly ash on the three major effects of concrete. Only by ensuring the stability of raw material quality of fly ash can the performance of fly ash to concrete be maximized Improve the positive role. Now on the market there are true and false fly ash, desulfurization ash, denitrification ash, floating black ash, etc., seriously affecting the concrete performance, mechanical properties and durability. How to identify the quality of fly ash? Buy poor quality fly ash should be how to deal with? 7 special planning to invite everyone to express their opinions.
