摘要
对普通混凝土试块掺加高效减水剂、早强减水剂,分别进行了劈裂抗拉试验和轴心抗拉试验,通过对试验数据和强度变化规律分析,探讨了混凝土早期劈裂强度和轴拉强度的关系,结果表明:在外加剂的影响下,混凝土的早期抗拉强度不同程度的得到提高。
Adding effective water reducing and early strength effective water reducing to common concrete sample, then do experiment of splitting strength and direct tensile strength. Discussing the relationship between splitting strength and direct tensile strength at early ages basing on analyzing of the data and regulation of concrete strength. The results of experiment show that with the influence of addictive, concrete strength at early ages will be promoted to some extent.
