膨胀补偿 meaning in English
expansion compensation
Examples
- The research of this text is about stopping " alkali - aggregate reaction " , reducing concretes exothermic peak , controling the internal concrete adiabatic storage and using the microexpansivity of magnesia to make up the shrinkage production in the later harden
本文从防止“碱集料反应” 、降低水泥水化放热峰、控制混凝土内部绝热温升和利用mgo微膨胀补偿水泥石硬化后期产生的收缩等方面进行研究与探讨。 - The technique of dam construction by weakly expansive concrete added with magnesia ( wecam ) is a new technique developed in china , in which appropriate light - burnt magnesia is added to dam concrete when produced to generate a special delayed expansive stress to compensate shrinking stress due to decrease of temperature so as to prevent concrete cracks . it not only is in favor of simplifing the method of temperature control and an effective solution to the crack problem of concrete dam , but also simplify the technology of dam construction and bring down the project cost , further more , speed greatly up the construction of concrete dam
外掺氧化镁微膨胀混凝土筑坝技术是指在生产大坝混凝土时，掺入适量的轻烧氧化镁，利用其特有的延迟膨胀补偿混凝土坝的温度应力，以防止混凝土坝产生的裂缝，这不仅有利于简化温控措施，有效地解决混凝土坝的开裂问题；而且简化了施工工艺，降低了工程造价，大大了加快施工进展。 - The shrinkage characteristics of hsc and normal concrete at short term and long term are researched . based on the above research , high performance expansive c50 - c80 concrete , which posses good expansive properties , excellent flow ability , low slump loss and hydration heat . in order to improve the anti - cracking of some important projects , such as cutting wall , the workability and bulk stability of fiber - reinforced micro expensive concrete are researched
