混凝土的蒸养强度与28d标养抗压强度的关系

The relation of the compressive strength of steam curing concrete and 28d concrete

通过试验研究表明适当提高混凝土的预养时间、降低升温速度能提高混凝土的抗压强度;当恒温温度较高时,混凝土前期强度较高,但28d强度有所降低。

The experimental studes show that can increase the compressive strength of concrete if appropriately increasing curing time of concrete,and reducing the speed of raising temperature; When the thermostat tem-perature is higher, the the early strength of concrete will be higher, but 28d strength decreased.
