BR型增强防水剂配制的混凝土,具有抗渗性能好、粘稠度高、密实性好、早强增强、操作简便等特点,在处理梅山铁矿透水性强的西南井水泵房的渗漏中,取得了安全、经济、快速的治理效果。(一)工作原理 BR型增强防水剂与水泥水化作用的生成物Ca(OH)_2反应,生成的产物是几乎不溶于水的凝胶状结晶型物质,即胶体。它是一种悬浮状的颖粒,充填在混凝土颗粒间隙之中,增强了混凝土的密实性,制止了Ca(OH)_2遇水析出,从而防止混凝土内部腐蚀造成的渗漏现象。素混凝土颗粒间隙为50～300微米,而水分子的直径为0.5微米。根据流体力学理论,只要素混凝土上方的水具有一定的压力,水就会透过混凝土
BR reinforced waterproofing agent formulated concrete, with good impermeability, high viscosity, good compactness, enhanced early strength, easy to operate and other characteristics of the Meishan Iron Mine in the permeability of Southwest well water pump leakage , Achieved a safe, economical and rapid management effect. (A) Working Principle BR type reinforced waterproofing agent reacts with Ca (OH) _2, a product of cement hydration. The product produced is a gel-like crystalline substance that is almost insoluble in water, ie, colloid. It is a suspension of Ying grains, filled in the concrete particles in the gap among, and enhance the compactness of concrete, to prevent Ca (OH) _2 precipitation with water, so as to prevent corrosion caused by concrete leakage. Plain concrete particle gap of 50 to 300 microns, while the water molecule diameter of 0.5 microns. According to the theory of fluid mechanics, as long as the water above the concrete has a certain pressure, the water will flow through the concrete
