喷射砼掺入不同钢纤维的性能对比研究［加拿大］戴维·Ｆ·伍德等我们在加拿大东部地区进行了两项钢纤维增强喷射征的试验研究。这两项研究分别采用了干式和湿式喷射工艺，在同等条件下用喷大板法取芯样和小梁，对其性能作出对比研究。本文介绍了这两项试验研究的结果，同...
Comparative Study on the Properties of Sprayed Concrete Mixed with Different Steel Fibers [Canada] David F. Wood et al. We conducted two pilot studies of steel fiber reinforced injection in the eastern part of Canada. The two studies, respectively, using a dry and wet jetting process, under the same conditions using the spray-plate method to take the core sample and trabecular, and its performance to make a comparative study. This article describes the results of these two pilot studies, with ...
