近几年出现的混凝土干湿热养护是一种新型的混凝土生产工艺,为提高混凝土产量,降低成本,找到了新途径。我们在学习已有经验基础上,用兰州地区的原材料进行了小规模试验,初步选定了养护方案,现将做法和体会介绍如下。一、干湿结合养护方案的选择 1.原材料:永登500号普通散装水泥,兰州产 In recent years, the maintenance of dry, wet and heat concrete is a new type of concrete production process. It has found a new way to increase concrete production and reduce costs. On the basis of learning from existing experience, we conducted small-scale experiments using raw materials from Lanzhou and initially selected conservation plans. Now we introduce the practices and experiences as follows. I. Selection of dry and wet combination maintenance program 1. Raw materials: Yongdeng 500 ordinary bulk cement, produced in Lanzhou
