混凝土试件在标准养护条件下,强度的增长往往有很好的规律性,但往往会有一个标准样品价值很高,但实体回弹估计价值不高,在混凝土结构的质量验收,混凝土固体强度回弹是一个重大的决定基础结构强度是合格的。混凝土本身的强度较大的离散性,各种影响因素非常复杂,通过数据分析,提高强度和固体强度回弹的偏差往往伴随着细沙的使用。所以有针对性的分析中使用特殊的细沙和细砂混凝土标准试件强度和实体的强度发展规律,协助日常质量控制。
Concrete specimens tend to have good regularity of strength growth under standard curing conditions, but often have a high value of a standard sample, but the value of physical rebound estimation is not high, the quality of concrete structures acceptance, concrete solid strength The rebound is a significant decision Infrastructure strength is qualified. Concrete itself, the strength of the larger discreteness, a variety of influencing factors is very complex, through data analysis, to improve strength and strength of the springback deviations are often accompanied by the use of fine sand. Therefore, the targeted analysis of the use of special fine sand and fine sand concrete strength and physical strength of concrete specimens developed to assist routine quality control.
