1.Introduction

HS-12 fast harden micro expansive cement with many kinds of chemical raw material, which processed by scientific proceed.

2.Advantage
a.Fast curing, instant water stop, while temperature above 10℃, solidify within 45 seconds.
b.High strength in early period, 1 hour pressure reach 15Mpa, 28 days pressure reach 40Mpa, later period pressure keep increasing.
c.Under water or wet air condition, induration have micro expansive function, expansion rate is 1‰~3‰, which provide a better sealing function for the leakge of seam or holes.

3.Application Range
a.Sealing for underground building, such as basement, shelter, tunnel and well etc.
b.Seaming for building chemical grounting.
c.Quick mending for cement structure, such as imperfection mend for road, bridge and wall.

4.Main Technical Index
Executive Standard: Q/HSF 004-2006

5. Usage

a. Water cement ratio is 0.4-0.5, put suitable quantity of clean water into container before put this model, quickly mix to blcok mass, and seal the water leaking place till solidification.

b. As reparing component for cement, we should clean the reparing place with water.

c. After molding, spraying water for maintenance in 3 days, at same time, avoid exposing under the sun.

6. Note

a. Mix it while using, not mix too early, which avoid material harden in advance, it will produce waste.

b. Material should be stored in dry place, and make damp proof measure, shelf life is half year. While finding block caused by damping, or it will be useless.
