LBT-0903 Cement Waterproof Coating Self-Sealing Tester

The cement-based waterproof coating self‑healing tester is a specialized testing instrument designed for evaluating the self‑healing properties of polymer‑cement waterproof coatings. Its primary function is to assess, under water exposure, the ability of the waterproof coating film to undergo physical and chemical reactions that enable cracks to self‑heal and seal. This equipment is widely used in building material testing laboratories, waterproof coating manufacturers, research institutions, and other settings, providing precise and reliable test data to support quality control and performance development of waterproof coatings. It fully complies with the requirements of GB/T 23445, “Polymer‑Cement Waterproof Coatings.”

LBT-0903 Cement Waterproof Coating Self-Sealing Tester

Description

Product Introduction:

Technical specifications:

Parameter Category	Technical Specifications
Connecting pipe	90°. Diameter 110 mm
Glass tube	Diameter 50 mm, length 300 mm
Height of the pressure plate from the center of the connecting pipe	200 mm

Test Procedure Description

1. Specimen preparation: Cut the PP membrane into standard 106 mm specimens, notch a 10 × 4 mm U‑shaped opening and secure it. Apply a waterproof coating 1.5–2.2 mm thick to the opposite side, cure and dry according to the specified procedure, then cut a standard 5 mm‑long crack.

2. Equipment Installation: Mount the test specimen between the horizontal end pressure plate and the connecting pipe, with the coated surface facing the water. After tightening, seal the joint with sealant; at the vertical end of the connecting pipe, install a pressure plate equipped with a glass tube and seal it as well.

3. Test Procedure: Fill the glass tube with clean water at 23°C, maintaining the water level at the specified height for the specimen. Observe the crack‑induced water seepage in real time and record the duration from the onset of seepage to its cessation.

4. Result Evaluation: After the test is completed, the specimen shall be conditioned under standard conditions for 24 hours, and the closure of any cracks shall be observed. Based on the time at which water penetration ceases, the self‑healing performance shall be evaluated.
