摘要
Abstract
The application of different mixed magnesium oxide expansion agent in mass concrete building engineering is studied;To solve the problems of temperature gradient and self-restraint stress caused by exothermic process in the hydration of concrete,The mechanism of action of the magnesium oxide expansion agent is introduced,The volume deformation of concrete was tested with different amounts of magnesium ox-ide expansion agent.The results show that the concrete mixed with expansion agent can effectively improve the crack resistance of concrete.Fi-nally,taking a water conservancy project as an example,according to the above research conclusions,the appropriate expansion agent is select-ed for compensation.The practical results show that the 5.5%magnesium oxide expansion agent selected in the paper can meet the safety and durability of engineering.关键词
