ZB-3型外加剂是大连北方信息联合开发公司技术开发部组织专家精心研究的成果。它是由减水剂、早强剂、抗剂剂、催化剂等复合而成。经过多年工程实践,证明它具有减少用水量,增加拌合物的和易性,早强,降低混凝土中液相的冰点,使新拌混凝土具有抗冻害的综合能力。该外加剂有如下突出优点:①不含氯盐,对钢筋无锈蚀作用。②可用于零下 The ZB-3 admixture is the result of meticulous research conducted by experts from the Technology Development Department of Dalian Northern Information Development Corporation. It is made up of water-reducing agent, early strength agent, anti-agent agent and catalyst. After years of engineering practice, it has proved that it has the ability to reduce water consumption, increase the workability of the mix, early strength, reduce the freezing point of the liquid phase in the concrete, so that the fresh concrete has the comprehensive ability to resist freezing injury. The admixture has the following outstanding advantages: 1 does not contain chlorine salt, no rust on the steel. 2 can be used for zero
