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
外摻氧化鎂微膨脹混凝土築壩技術是指在生產大壩混凝土時，摻入適量的輕燒氧化鎂，利用其特有的延遲膨脹補償混凝土壩的溫度應力，以防止混凝土壩產生的裂縫，這不僅有利於簡化溫控措施，有效地解決混凝土壩的開裂問題；而且簡化了施工工藝，降低了工程造價，大大了加快施工進展。 -
