Use of pulp-ash as an admixture for concrete

研究人员发现，如果可以改善和易性，研磨后的纸浆灰分可以用作混凝土的外加剂，并且从试验结果中可以推断出与和易性和抗压强度相关的理想灰分细度为6000<正负>2000cm^2/g。在本研究中，研究了这种灰替代20%水泥的混凝土的和易性和抗压强度，并证明了上述细度的适宜性。

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.
