| 摘 要： | 针对工业厂房大面积地面混凝土采用普通商品混凝土施工时容易产生裂缝的问题,通过采用掺高效减水剂、粉煤灰、膨胀剂等方法,配制出具有高抗渗、高抗裂、具有一定补偿收缩作用的混凝土;对于有耐磨要求的特殊地面,在普通补偿收缩混凝土中掺入一定量的钢纤维使混凝土的力学性能、抗渗抗裂性能、耐磨性能大大提高。

| Abstract: | The industrial factory floor using commodity concrete in mass area is easily apt to crack in construction.Against this problem,the concrete is prepared with high efficiency water reducer,fly ash and expansive admixture.For wear-resistant floor,some steel fiber is added into common expansive admixture concrete,consequently the mechanical properties,anti-penetration,anti-crack and abrasion resistanceetc are improved. |

| Keywords: | composite admixture expansive admixture concrete steel fibe abrasion resistance |
