粉煤灰系列干拌砂浆粉的试验研究

利用低品质粉煤灰研制出粉煤灰系列干拌砂浆粉。研究表明 :粉煤灰掺量65%～75%时 ,可以配制M2.5～M5.0或M7.5～M10.0砂浆粉 ;粉煤灰掺量55%～60%时 ,可以配制M10.0～M15.0或M15.0～M25.0砂浆粉 ;粉煤灰掺量45%～50%时 ,可以配制M25.0～M30.0砂浆粉。同时 ,对利用上述砂浆粉配制的建筑砂浆的性能进行了研究。

The fly ash series dry mixing mortar powder has been developed by using low quality of fly ash. The study shows when the addition of fly ash is 65%～75%, the mortar powders M2.5～M5.0 or M7.5～M10.0 can be prepared; when the addition of fly ash is 55%～60%, the mortar powder M10.0～M15.0 or M15.0～M25.0 can be prepared; when the addition of fly ash is 45%～50%, the mortar powder M25.0～M30.0 can be prepared. At the same time, the study on properties of building mortar by using above mortar powders has been carried out.
