Description

ASTM C403 Mortar Penetrometer – Mortar Hardening Test Tool | Azalab

The Azalab ASTM C403 Mortar Penetrometer is a high-precision testing device used to measure the rate of hardening of mortar extracted from freshly mixed concrete. The instrument provides accurate penetration resistance readings, as required by ASTM C403, enabling quality control engineers to determine both initial and final setting times of cement-based mixtures.

The apparatus consists of a calibrated spring mechanism connected to a stem graduated from 0 to 70 kg in 1 kg increments. A sliding ring indicates the force exerted during testing. Six interchangeable stainless steel needles of different surface areas are included for various stages of mortar stiffness.

The penetrometer is suitable for both laboratory and field use and is supplied in a wooden carrying case for safe storage and portability.aza

Frequently Asked Questions (FAQ)

Q1: What is the purpose of this penetrometer?
It measures the penetration resistance of mortar to determine its setting time and hardening rate, as per ASTM C403.

Q2: Can it be used with concrete directly?
No – the test is conducted on mortar sieved from fresh concrete, not the full mix.

Q3: What are the surface areas of the supplied needles?
Six needles are provided with the following areas: 645, 323, 160, 65, 32, and 16 mm².

Q4: How is the penetration measured?
Penetration resistance is gauged by the force required to penetrate 25 mm of mortar, marked on the stem and indicated by a sliding ring.

Q5: Is calibration required?
Yes – for accurate results, periodic calibration is recommended. Azalab offers calibration services upon request.
