The invention discloses a tester of cement setting time. The tester of the cement setting time comprises a base, a support, a test needle and a test needle control support, wherein the base and the support are perpendicularly fixed, and the test needle is fixed on the test needle control...
Accurate Cement Testing: The Vicat apparatus is designed to ensure precise testing of cement consistency and setting time, providing reliable results for quality control in construction projects. Compliance with International Standards: This product is manufactured in accordance with ISO standards, guaranteei...
Vicat apparatus, also called cement consistency setting time tester. It is a testing instrument for cement and concrete industries. It is mainly used to test the standard consistency water requirement and setting time of cement paste.This instrument is mainly suitable for Portland cement, ordinary...
In contrast to the Vicat needle test, the USWR method gives continuous information on the stiffening and hardening process over time via r changes, as the rigidity of the pastes grow on hydration. The magnitudes of the r change in selected cement pastes (CEM I 52.5R and PC 30dz 45s) ...
It is used for determination of setting time and consistency of cement by Vicat Method. The apparatus consists of a metal frame with a sliding rod. An adjustable indicator moves over a graduated scale. The needle or plunger is attached to the bottom end of the rod...

time when the plasticity losing of the cement slurry is completed. The setting time is often measured by Vicat Apparatus, referring to the measurement method provided in “Test Methods for Water Requirement of Normal Consistency, Setting Time and Soundness of Portland Cement” (GBT1346–2001)[10]...
It was stated that this period corresponds to the time needed for the concrete to have a compressive strength of 7–8 kgf/cm2. Alexanderson [5] observed that the expansions can be neglected for delay periods of 4–7 h (depending on water–cement ratio) and no strength loss was observed...
