摘要
本文阐述了混凝土早期裂缝的危害及成因。提出过度追求水泥的高早强、高用量以及不适当的使用膨胀剂是一种误区。重申加强早期湿养护、适量掺加优质粉煤灰或磨细矿渣是防止早期裂纹的有效措施。强调开展混凝土最早期性能研究的必要性。
This article expounds the harmfulness and causes of concrete early crackings,puts forward that excessive pursuit of high early strength and high consumption of cement and the inappropriate use of expanding agent is a misunderstanding,restates that to strengthen the early moist curing and to appropriately add quality fly ash or ground slag is an effective measure to prevent concrete early crackings and stresses the necessity of developing research on the very early ages properties of concrete. 〔
