Use of pulp-ash as an admixture for concrete

研究人员已经发现，如果能改善和易性，研磨后的纸浆灰可以用作混凝土的外加剂。根据试验结果，可以推断出灰在和易性和抗压强度方面的理想细度为6000 <plus-minus>~ 2000 cm ^2/g。本研究考察了掺量达20%的粉煤灰混凝土的工作性和抗压强度，证实了粉煤灰细度的适宜性。

Investigators have revealed that grinded pulp-ash may be useful as an admixture for concrete, if some improvement of the workability can be achieved, and that the desirable fineness of ash with respect to workability and compressive strength may be inferred as 6000<plus-minus>2000cm^2/g from the results of the test. In this study, the workability and compressive strength of concrete admixed with such ashes substituting up to twenty percent of cement was investigated and the appro-priateness of the fineness as stated above was testified.
