| Abstract: | The applying area of expansive agent for concrete becomes wider and wider in morden engineering. The paper proposes expansive agent for concrete prepared with fly ash and phosphogypsum by the technology of dehydrated hydrates phases. The experiment indicates the expansive agent can achieve the limited expansion ratio in water requested by the expansive agent criteria. |
