作为混凝土技术人员,常常挂在嘴边最频繁的词语就是“强度”两字了,强度是混凝土材料技术人员日常工作最主要的目标。为了达成这个目标,首先要充分了解混凝土组成材料性能的优劣,比如说水泥的富余值大小以及正态稳定区间,水泥中的基本外掺料的品种以及掺量;骨料的级配、含泥量;掺合料的活性,吸附性;外加剂减水率等,以及各种原材料混合后的相容性,这是混凝土设计人员配合比设计的基础。配合比设计是影响强度不足原因之一,配合比设计完
As a concrete technician, the most frequently used term often refers to the word “strength”, which is the most important goal of daily work of concrete material technicians. In order to achieve this goal, we must first fully understand the pros and cons of the performance of concrete materials, such as the size of the surplus value of cement and the normal stability interval, the basic types of cement admixtures and dosage; Grades aggregate, containing Mud amount; admixture activity, adsorption; admixture water reduction, and a variety of raw materials after mixing compatibility, which is designed concrete mix design basis. Mix design is one of the reasons for the lack of strength, with the design finished
