概述
产品名称:RA100 Concrete
描述:
RA100 混凝土、砂浆、水泥抗压强度和弹性模量测试系统利用外部激发使试件内部产生振动,利用麦克风收集装置收集共振频率,通过共振曲线图在屏幕上进行视觉反馈,可以立即评估测量质量。
RA100具有快速,无损、便捷、无须样品表面特殊处理,样品与采集装置更不需要耦合,样品与仪器无需位置校准只需几秒就可确定材料的抗压强度和弹性模量。长达六小时的供电系统和无线数据库远程访问使RA10不但适用于试验实验室更适合野外工地现场检测,超大坚固的测试台可测试更大范围的样品。
RA100采用共振分析确定样品的弹性模量和抗压强度,与超声测量相比,共振频率的测量更具有优势, 与超声传输时间测量相比,更容易和更,共振频率采集装置比超声波传感器更容易使用。

Reference to Standards 参考标准:
• Resonance measurements of concrete test specimen for determination of dynamic modulus of elasticity are described in American ASTM C215, British BS 1881-209
美国ASTM C215,英国BS 1881-209中描述了测定动态弹性模量的混凝土试件的共振测量.
• Dynamic modulus of elasticity can be converted to static modulus of elasticity by established reference curves. Direct measuring of static modulus is standardized in European EN 12390-13 and American ASTM C469
通过建立的参考曲线,动态弹性模量可以转化为静态弹性模量。欧洲EN 12390-13和美国ASTM C468标准化了静态模量的直接测量.
• Compressive strength can indirectly be determined by calibration with the measured sound velocity. Standardized measurement of compressive strength are usually made according to European EN 12390-3 (cube, cylinder), EN 196-1 (mortar prism) and American ASTM C39 (cylinder)
抗压强度可以间接地通过测量的声速校准来确定。抗压强度的标准化测量通常根据欧洲EN 12390-3(立方体、圆柱体)、EN 196-1(砂浆棱柱体)和美国ASTM C39(圆柱体)进行。
• In the freeze-thaw resistance test standards European CEN/TR 15177 and American ASTM C666 the relative change of the dynamic modulus of elasticity is used to evaluate internal structural damage
在欧洲CEN/TR 15177和美国ASTM C666抗冻融试验标准中,动弹性模量的相对变化被用于评估内部结构损伤。
