| Abstract: | Cracks in bulky concrete will reduce the strength and frost resistance of concrete, which has bad effect on the impermeability and durability of concrete. In the construction of bulky concrete cushion cap of separated interchange at Tangshan-Caofeidian expressway, the cracks in bulky concrete cushion cap are better controlled by optimizing raw materials, designing mix proportion reasonably, enhancing the maintenance of concrete, supervising the interior temperature and advancing the construction techniques,... |
