Technical parameters of Hanji cement blanket

2) Setting time

Initial setting ≥ 120 minutes; final setting ≤ 240 minutes.

24 hours after the hydration reaction, the cement blanket can reach 80% strength.

3) Hydration reaction

The cement blanket can be hydrated with brine or non-brine. The minimum weight ratio of water to cement blanket is 1: 2. Cement blankets do not cause excessive hydration reactions, so it is always recommended to use excess water. Water can be sprayed on the fiber surface multiple times until the cement blanket reaches saturation. Because the cement blanket absorbs moisture, the color darkens first and then becomes lighter. When water accumulates or flows down on the surface, it indicates that the cement blanket is saturated with water. After the initial hydration reaction, the cement blanket should be re-wet at least once between one and two hours. In high temperature and dry weather, this is especially necessary, because the evaporation of water will cause the concrete to dry excessively.

The product HJ008 cement blanket is the most prone to over-drying. Regardless of the weather, it should be re-wet one or more times after one to two hours after the hydration reaction. Never use a high-pressure water spray gun to spray water directly on the cement blanket, otherwise the surface of the cement blanket will be washed into a groove shape. If the cement blanket is not sufficiently protected by water, setting will be delayed and the material strength

Will fall. If the setting time is delayed, re-wet it with plenty of water. The cement blanket can be used underwater, at this time, because it is immersed in water, the hydration reaction can fully occur.

4) Strength

The initial strength of the new cement blanket is very high, which is the basic feature of this material.

Typical strength and physical characteristics are as follows:

① Compressive strength test according to ASTM C473-07

— 10 days compression failure stress 40 MPa

② Bending test according to BS EN 12467: 2004

— 10 days bending failure stress 3.4 MPa

— Ten-day bending Young's modulus 180 MPa

③ Abrasion resistance test according to DIN 52108

— Similar to ceramics in wear resistance up to 0.10 g / cm2

④ Mohs hardness 4 – 5

⑤ CRB puncture resistance according to EN ISO 12236: 2007 (HJ008 only)

— Minimum thrust penetration 2.69 Kn
