摘要:
试验研究了粉煤灰掺量对早龄期混凝土劈裂抗拉强度、自收缩、拉伸弹性模量、拉伸徐变和轴心抗拉强度的影响。结果表明:混凝土的劈裂抗拉强度、自收缩、拉伸弹性模量和拉伸徐变均随着粉煤灰掺量的增加而逐渐减小; 混凝土的轴心抗拉强度也随着粉煤灰掺量的增加而逐渐减小,但长期拉伸荷载作用可使混凝土的轴心抗拉强度降低。
Abstract:
Experimental study on the influences of the content of fly ash on the splitting tensile strength, autogenous shrinkage, tensile modulus, tensile creep and axial tensile strength are studied in this paper. The results indicated that splitting tensile strength,autogenous shrinkage, tensile modulus and tensile creep decreases with increasing of content of fly ash. Axial tensile strength of concrete decreases with increasing of content of fly ash too, but under long-term tensile load the axial tensile strength of concrete is reduced.
