| 摘 要： | 再生微粉经过球磨机粉磨后,制备微粉水泥砂浆,再生微粉掺量在10%以内对其砂浆的抗压强度影响较小,掺量大于10%其抗压强度呈直线下降。为了进一步研究再生微粉的性能,通过试验,研究表明当粉煤灰掺量为15%、减水剂掺量为0.5%、石膏粉为0.6%、石灰粉为10%和碳酸钠掺量为0.6%时其微粉水泥砂浆的抗压强度值达到最大值。

| Abstract: | The recycled powder cement mortar is produced by the recycled powder,which is grinded by the ball mill.When the recycled powder content is lower than 10%,the compressive strength of the powder cement mortar has a small influence,and can be reduced when more than 10%.For the further study on the performance of the recycled powder,the results show that,when the fly ash content is 15%,water reducing agents content is 0.5%,CaSO4 content is 0.6%,CaO content is 10% and Na2CO3 content is 0.6%,the compression inten... |
