摘要
塑性混凝土作为柔性防渗墙材料被广泛的应用于防渗止水地下工程。对于低强度、弹性模量小的塑性混凝土能否经受冻融破坏?通过固定膨润土掺量,改变水泥用量;固定水泥用量,改变膨润土掺量;掺入黏土和外加剂的研究,在塑性混凝土里掺入引气减水剂,可以大幅度的提高混凝土的抗冻性。
Plastic concrete is adopted as a wall anti-penetrating flexible material extensively for underground engineering to stop water from penetrating into the interior.But in consideration of its low strength and elastic modulus at small value, is it able to resist freeze-thaw damages?It's proved that the frost resistance of the concrete might be enhanced dramatically by blending with air entraining and water reducing agents through studies on fixing the amount of mixed bentonite or cement dosage to change the cement dosage or the amount of mixed bentonite and on mixing of clay soil and additives.
