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.

研究人员发现，如果可以实现和易性的一些改善，则磨碎的纸浆灰可用作混凝土的外加剂，并且从测试结果可以推断出就和易性和抗压强度而言所需的灰细度为 6000±2000cm^2/g。在这项研究中，研究了掺有这种灰烬的混凝土的和易性和抗压强度，该灰烬取代了百分之二十的水泥，并验证了上述细度的适当性。
