Non contact bellows self shrinkage tester made in China

Product Introduction

This equipment is used to measure the volume strain of mortar or concrete in the plastic stage by measuring the length in a horizontal direction. It adopts advanced bidirectional non-contact measurement method, which can not only achieve continuous monitoring of the self shrinkage of concrete or cement-based materials from the beginning of self pouring molding, but also effectively avoid the influence of gravity, temperature changes, and mold constraints on the test results.
