混凝土收縮測(cè)量儀　　

Shrinkage measurement of concrete and mortar normalized prisms

Description - Principle

Concrete drying shrinkage can be measured in laboratory. The American Concrete Institute (ACI) 302 Guide for Concrete Floor and Slab Construction recommends following ASTM C157 “Standard Test Method for Length Change of Hardened Hydraulic-Cement". In this way, CAD Instruments developed and offers 2 devices for measuring the length variation of concrete or mortar prism along drying time. These 2 instruments, called retractometer 混凝土收縮測(cè)量儀RE101040 and 混凝土收縮測(cè)量儀RE4416, are robust and accurate to control specimens according to ASTM C151, ASTM C490, BS 1881, EN 1367-4, EN 12617-4, NF P15-433 and NF P18-427 norms.
