Specification

YH - SN type flash setting admixtures is widely applied for national engineering quick-setting products, its technical performance and economic benefit is better than the domestic similar products, can be widely used in railway, highway transportation, tunnels, coal mine, such as water and electricity, military sprayed concrete engineering.Product standards: JC477-2005.
Technical performance

1, this product is weak alkaline, non-toxic, no chlorine, no stimulation.For reinforcement corrosion.
2, the appropriate mix content is 5% by weight of the cement.
3, this product and cement adaptability is good, the initial setting is less than 5 min, final set is less than 12 min, 1 d compressive strength is not less than 6 mpa, 28 d compressive strength is not less than 75%, conform to the JC477-2005 technical indicators.
4, added to the product of the shotcrete good adhesiveness, low rebound, a jet thickness, high permeability, good effect, has obvious economic benefits, improve the quality of engineering.
Construction requirements

1, before using, application of the product and construction of cement adaptability test, to determine the optimal dosage.
2, when using, should accurate measurement, open after the bag should be finished, the site should be moistureproof measure, keep good coagulation effect, make the accelerator does not affect the construction schedule.
3, such as cement agglomerate or low temperature on the construction site, should be temporary according to actual situation well adaptability test, determine the best dosage on the construction site, does not affect the quality of the project.
