白银牌BY12-6型水中不分散灌浆料:主要应用于岩体活动水和突水的堵漏,使用时开动高速搅拌机将1 000kg BY12-6型加入到600 kg水中搅拌15 min,然后用压浆泵将浆液压进岩体、隧道矿井结构混凝土(管片)背后或酥松裂缝有缺陷的混凝土,当桨体与水接触时不会被水分散,随着压浆泵压力的加大,浆液逐渐把缝隙中的水挤到半径1~50 m以外。性能指标:水料比0.6,初始流动度40 s、60 min流动度50s,初凝时间72h、终凝时间96 h,0泌水,1d竖向膨胀率1%左右,水中7d抗压强度大于5 MPa,水中28 d抗压强度大于15
Silver Type BY12-6 non-dispersible grout in water: It is mainly used in plugging of active water and water inrush. When using, start high-speed mixer and add 1000kg of BY12-6 to 600kg of water and stir for 15 min, Slurry slurry pump into the rock, tunnel structure of concrete behind the mine (pipe) or crisp cracks flawed concrete, when the paddle and water contact will not be water-dispersed, with the pressure of the grouting pump increases, the slurry Gradually squeeze the water in the gap to a radius of 1 ~ 50 m away. Performance indicators: water ratio of 0.6, initial flow 40 s, 60 min flow 50 s, initial setting time 72 h, final setting time 96 h, 0 bleeding, 1 d vertical expansion rate of about 1%, water 7d compressive strength greater than 5 MPa, 28 d in water compressive strength greater than 15
