The emulsified asphalt and cement mixing tester is used to test the mixing stability and demulsification rate of emulsified asphalt and cement, and to evaluate its fast cracking, medium cracking or slow cracking type. It is a commonly used emulsified asphalt testing equipment in road engineering and laboratories.

Asphalt Emulsion–Cement Mixing Tester

Model:TD657-1

I. Product Introduction:

The Emulsified Asphalt and Cement Mixture Tester (also known as the Emulsified Asphalt Demulsification Rate Tester) was developed and manufactured by Hebei Tianqixingzi Inspection Equipment Co., Ltd. in accordance with the People's Republic of China industry standard: JTG 3410-2025 "Standard Test Methods of Asphalt and Asphalt Mixture for Highway Engineering" (T 0657-2025 "Emulsified Asphalt and Cement Mixture Test").

This equipment meets relevant national standards and technical specifications for the petrochemical industry. It is primarily used to determine the mixing stability of various emulsified asphalts. By observing their reaction process with cement, the demulsification characteristics of the emulsified asphalt are assessed, thereby determining whether it belongs to the fast-cracking, medium-cracking, or slow-cracking type.

II. Product Uses and Functions

This instrument is mainly used to determine the reaction performance and mixing stability of emulsified asphalt under cement contact conditions. It has the following functions:

Assessing the demulsification rate of emulsified asphalt;

Determining the type of emulsified asphalt (fast cracking/medium cracking/slow cracking);

Analyzing the compatibility of emulsified asphalt with cement;

Simulating mixing behavior in actual construction;

Providing a basis for emulsified asphalt formulation design and quality control, etc.

III. Product Structure

The emulsified asphalt demulsification rate test mixing system mainly consists of the following parts:

Electric drive motor; Standard mixing paddle system; Stainless steel mixing container; Speed control system

The equipment uses a motor to drive the mixing paddle to rotate at high speed and stably, ensuring thorough mixing of emulsified asphalt and cement, and realizing the dispersion, mass transfer, and demulsification reaction processes (including dissolution, extraction, and adsorption).
