摘要
粉煤灰与矿粉复掺对胶凝材料水化热、胶砂早期抗裂性和混凝土性能影响的结果表明,改善了新拌混凝土的和易性,在满足强度指标的同时,提高混凝土的抗渗性能,减少混凝土中水泥用量。
Authors study on the influence of different mixing of fly ash and coal ash on hydration heat,anti-cracking at early age and strength and durability of concrete.The results show that after some cement is replaced by fly ash and coal ash,the performance,strength and durability of concrete are all greatly improved,which can effectively reduce the production costs of concrete.
