【Abstract】 When bulky structure pours concrete , cracks puzzle it. The treatise links up with the example to raise a point of resolvent about the cause of prouducing cracks in construction. To utilize intumescent concrete prevents structure from making water and resist crazing. By analyzing construction jawboning and technic measures, we discussed optimization project for construction without cracks, in this paper.更多还原
