粉煤灰影响海水海洋骨料水泥基材料抗压强度试验研究

通过试验测定不同粉煤灰掺量下的海水水泥净浆、海水海砂砂浆以及海水海洋骨料混凝土的抗压强度,研究粉煤灰掺量对海水海洋骨料水泥基材料抗压强度的影响。试验结果表明,随着粉煤灰掺量的增加,海水水泥净浆和海水海砂砂浆的抗压强度逐渐降低,海水海洋骨料混凝土抗压强度表现为先增大后减小。粉煤灰掺量对海水海洋骨料水泥基材料抗压强度的影响规律与粉煤灰掺量对淡水河砂水泥基材料抗压强度的影响规律基本一致,但影响程度略小于淡水河砂水泥基材料。

Experimental study on compressive strength of cement-based materials of seawater and marine aggregate affected by fly ash

The compressive strength of seawater cement paste,seawater sea sand mortar and seawater and marine aggregate concrete under different fly ash content was determined by experiments,and the compressive strength of seawater marine aggregate cement-based material was studied by the amount of fly ash influences.The test results show that with the increase of fly ash content,the compressive strength of seawater cement paste and seawater seasand mortar is gradually reduced,and the compressive strength of seawater aggregate concrete first increases and then decreases.The influence of fly ash content on the compressive strength of seawater marine aggregate cement-based materials and the influence of fly ash content on the compressive strength of freshwater river sand cement-based materials are basically the same,but the impact degree is slightly less than that of freshwater river sand cement base material.
