摘要
本文采用萘系减水剂、硅粉、粉煤灰及粘度调节剂通过一定比例复配成一种新型的透水混凝土胶结剂。研究发现,萘系减水剂:硅粉:粉煤灰:007建筑用速溶胶粉=20:32:47:1时,该透水混凝土胶结剂性能最好。并用该样品进行了相关的透水混凝土性能测试。实验表明,该复配样品具有成本低、减水率高、透水率好等优点。
A new type of permeable concrete cementing agent was developed by consisting of a mixture of napthalene superplasticizer powder,silica powder,fly ash and binding agent.The results showed that the performance of permeable concrete cementing agent was developed was best when napthalene superplasticizer powder：silica powder：fly ash ：binding agent =20：32：47：1. The developed samples were used to carry out related permeable concrete test experiments.Also,it has low cost,high water-reducing capability and fine water-permeability.
