High-strength Fast-hardening Plugging Cement
Introduction
● High-strength Fast-hardening Plugging Cement,also named Rapid-setting Plugging Binder, is a kind of special building material for preventing seepage, block seeping, filling crack and rushing to repair project.
● Because of its Excellent character of rapid-setting, high strength and micro-expansion, it is largely used in the construction of rapid-blocking and urgent rushing to repair, for example the tunnel, underground, reservoir and dam, culvert, mine, rooftop, basement, pressure pipe, pool, toilet, military affairs construction, etc.
Characteristics
● Rapid setting,
● Fast hardening,
● Early strength,
● High strength,
● Micro expansion.
Specification
● When W/C at 0.25 to 0.35,
Setting: initial time 1 to 4 minutes, final time 2 to 5 minutes;
● Mortar Strength after hardening:
10Mpa Min(at 15 minute), 30-50Mpa(at 30minute), 50Mpa Min(at 1d)
Application
Rapid-setting Pluging Cement is usually used in the following projects:
● To block in the subconstruction, pool, toilet;
● To block the crack of door, window, piping and the tie-in of pipe;
● To prevent seepage, block seeping, fill crack and rush to repair in the tunnel, underground, reservoir and dam, culvert, mine, rooftop, wall, basement, pressure pipe, etc.
● To make the cement products that is requested to rapid setting, fast hardening and fast demould.
● To be used in emergency road construction or other emergency repair works.
Dosage and Usage Way
● Recomendded Water Cement Ratio: 0.25 to 0.35
● When constructing, cutting a hole with the reverse V shape.
Between initial setting and final setting, when the slurry starts heat and hardening, fast squeeze the slurry into the nozzle bore or seam, then to impact it with the presswood or bolt. After about 10-20 minutes, unloosen the presswood or bolt and the nozzle bore or the seam is blocked.
Storage, Transportation and Packing
● To be stored in dry ventilation storage
● Transportation: as per the common goods; classification for conveyance - not to be required; not to allow the packages to be fallen down or damaged
● Package: plastic woven bag, 25kg/bag, and /or 1MT jumbo bag
