Embodiment Construction
[0023] The present invention will be further described in detail through specific embodiments below.
[0024] Difficulties in controlling the temperature of mass concrete include: 1. The characteristics of the structure are mostly pumped into the warehouse. How to meet the optimal match of concrete pumpability and slump on the basis of reducing the heat of hydration of cement; 2. Construction technology And the impact of process optimization on temperature control requires a large number of on-site test demonstrations.
[0025] The method of the invention conducts construction technology research from various processes such as raw materials, mix ratio research, horizontal transportation, vertical transportation, and maintenance, so as to control the concrete temperature and reduce defects such as cracks in the pumped concrete structure of water conservancy projects, and under the premise of ensuring the quality of the concrete. Big cost savings.
