摘要
试验研究表明,掺加适量的减水剂、纤维素和引气剂均能从不同方面对砂浆性能起到一定的改善作用,但单独使用时作用有限,甚至会产生负作用。TJS砌筑砂浆外加剂是由合适粘度的纤维素、引气剂和适应性最佳的减水剂复合而成的,掺水泥重量0.2%的TJS外加剂所配制的砂浆其各项性能均优于掺石灰膏的砂浆,具有良好的应用前景。
The experimental study shows that adding of water-re-ducing agent,cellulose and air entraining agent can improve mortar performance from different aspects.If these agents are used separate-ly,their functions are limited even negative.TJS admixture is com-posed of cellulose with proper viscosity,air entraining agent and wa-ter-reducing agent with optimum adaptability.The performances of the mortar added with TJS admixture(with the dosage of0.2%cement in weight)are better than that of the mortar blended with lime paste.Admixture Tjs has a good application prospect.
