About Concrete Penetrometer - Spring Type
Compliance With Following International Standards:
ASTM C403, IS:8142,IS:1199-part7
This test is used to determine the elapsed time between batching of a concrete sample and when it is deemed by standard methods to have set. The method involves measuring the penetration resistance of a test sample, which has had coarse particles removed at periodic intervals. It is particularly useful, in determining the effect on setting time of admixtures in the concrete, where these may have been introduced specifically to increase the setting time.

FAQs of Concrete Penetrometer - Spring Type:
Q: How is the Concrete Penetrometer - Spring Type operated during testing?
A: This penetrometer is manually operated using its spring-loaded plunger. You press the mechanical push rod onto the mortar cube surface, and the graduated analog scale shows the penetration resistance instantly without requiring any external power source.
Q: What applications is this penetrometer ideally suited for?
A: The device is designed for determining the elapsed time between batching of a concrete sample and its initial set, as outlined in standardized testing methods. Its specifically useful for monitoring penetration resistance in laboratory or field conditions where accurate setting time assessments are needed.
Q: When and where should the penetrometer be used for optimal results?
A: Use the instrument in controlled laboratory environments or onsite during concrete batching and curing processes. Testing should follow standard laboratory conditions for temperature and humidity to maintain accuracy, and results are most reliable when applied to mortar cube surfaces.
Q: What is the process for using the penetrometer to measure concrete setting time?
A: Prepare a mortar cube specimen, position the penetrometer, and manually push the spring-loaded plunger to penetrate the surface. Read the force value on the graduated analog scale. Repeat this process at intervals to determine the setting time based on penetration resistance measurements.
Q: What benefits does this equipment offer to construction professionals?
A: It provides immediate, precise readings of concrete setting progress, facilitating timely quality control without the need for electricity. Its compact, portable design makes it easy to use onsite or in laboratories, and the supplied calibration certificate assures reliable accuracy for compliance with industry standards.
Q: How do I ensure accurate measurements with the penetrometer?
A: Always use the device under standard laboratory conditions, on properly prepared mortar cube surfaces, and refer to the supplied calibration certificate. Regular calibration and correct manual operation help maintain the accuracy of 1 kg/cm2 across the measuring range.
