Construction technology of mass concrete The pouring amount of large volume is too large, and the overall requirements are high. During the pouring, tamping and curing process, a large amount of hydration heat is generated from cement hydration. However, due to its large volume, a large amount of hydration heat cannot be distributed. The internal temperature of the concrete is higher than the temperature of the outer concrete, resulting in a large temperature difference. Due to the different volume expansion between the surface and the inside, temperature cracks will be generated, so the hydration heat is reduced, Place the concrete inside and outside -

Construction technology of fair faced concrete formwork In the erection process of clear water formwork, ordinary scaffold tubes are used instead of square timber skids to reinforce the formwork, which can save a lot of timber, reduce the project cost, and have good economic benefits, energy conservation and environmental protection benefits. The key points of scaffold tube reinforcement formwork technology are the fixing method of steel pipe and the safety control during formwork removal. -
Discussion on construction technology of impermeable concrete [Abstract] We often come into contact with the waterproofing of buildings. In fact, waterproofing and impermeability have a lot of similarities, but different concrete is used because of the different impermeability of buildings required by the design or because buildings cannot use other additional waterproof materials. Impermeable concrete shall be used if there are specific requirements for anti permeability. And put forward prevention and treatment measures. -

Construction technology standard of fair faced concrete in a certain place Fair faced concrete is a concrete project that is formed at one time without any external decoration, and the natural color of cast-in-place concrete is directly used as the finish. It is different from ordinary concrete. Its surface is very smooth, with sharp edges and corners. There is no wall decoration at all. It is just coated with one or two layers of transparent protective agent on the surface, which can be directly used as the exterior decoration.
