粉煤灰对垃圾锚固材料性能的影响

研究了不同掺量的粉煤灰对垃圾锚固材料性能的影响,结果表明,锚固材料中掺入一定量的粉煤灰后,由于粉煤灰的火山灰反应,随着龄期的延长,抗渗能力和材料力学性能都有所提高;并且随着粉煤灰掺量的增加,锚固材料的抗渗能力也将提高.当粉煤灰掺量为24%时,所得的锚固材料的流动度最佳,因此可以容易地被喷射到垃圾堆表面以固结垃圾.

Influence of Fly Ash on Properties of Rubbish Anchoring Material

The influence of different amount of fly ash on properties of the rubbish anchoring material is investigated. The experimental results indicate that the pozzolanic reaction of fly ash takes place after a certain amount is added into the anchoring material. As the age is prolonged,the permeability and mechanical properties of the anchoring material are improved. Similarly,the more amount of fly ash is incorporated,the better the permeability of the anchoring material will be. While the fly ash is amounted 24 %, the fluidity of the rubbish anchoring material is optimal. So the anchoring material can be applied easily to the surface of the rubbish piles.
