late strength meaning in English

后期强度

The tests show that the activity of the compound admixtures of lithium - salt residue and fly ash is higher than that of fly ash and there is a optimum ratio between the lithium - salt residue and fly - ash . the activity of the compound admixtures is of importance for the later strength of concrete , especially for the 60d and 28d strength
大掺量复合掺合料混凝土强度试验中，该复合掺合料活性对混凝土后期强度的提高很重要，尤其60d 、 28d强度增长较大，但180d比60d增长幅度较小。
The results show that the water soaking is vital to microstructure , its influence on shear strength is higher than it on deformation properties of clayey soil obviously ; when number of blows of more wet and vibrated soil increased , the damage of initial construction increased , but the later strength of construction increased for a little
结果表明，水的浸入对土的微结构特性影响至关重要，对土的抗剪强度的影响明显高于土的变形特性，偏湿上和受振动的土击数越多，对土的初始结构损伤越厉害，但土的后期结构强度有所提高。
