STC 型粉状喷射混凝土粘稠剂由多种有机高分子化合物聚合而成,无毒,对人体无腐蚀性,运输、保管、使用方便、安全,是一种新型的喷射混凝土外加剂。其掺量为水泥重量的2%。掺 STC 型粉状粘稠剂的喷射混凝土,其抗压强度、抗拉强度、与钢筋握裹力、与岩石面粘结力、抗渗能力、耐腐蚀性、干收缩性能等均优于单掺速凝剂的混凝土。该粘稠剂具有良好的技术、经济及社会效益。主要表现在:
STC powdered shotcrete viscous agent is made of a variety of organic polymer compounds, non-toxic, non-corrosive to the human body, transport, storage, use of convenient and safe, is a new type of sprayed concrete admixture. Its content is 2% of the weight of the cement. Shotcrete with STC-type powdered viscous agent is superior to single-strength concrete in its compressive strength, tensile strength, bond strength with steel bar, adhesion to rock face, impermeability, corrosion resistance, and dry shrinkage. Concrete with a quick-setting coagulant. The viscous agent has good technical, economic and social benefits. Mainly in:
