Abstract

The invention relates to a green building ready-mixed mortar and a green construction method thereof. The ready-mixed mortar is prepared by stirring and mixing cement, thickened powder, colored slag, methyl cellulose ether, water reducing agent, gypsum, and a slow-release heat-absorbing agent. to make. The construction method of the ready-mixed mortar includes a batching and mixing process, a sampling and testing process, a suction and transportation process, and a water-adding and stirring construction process. The components of the ready-mixed mortar are designed reasonably, and the resulting concrete has good adhesion and strong adaptability to temperature differences. During the curing period of the concrete, the temperature difference between the interior and the surface is small, and the concrete is not easy to crack, thus ensuring the durability of the project. The construction method can realize the integration of pulping, detection, transportation, pouring and remote control, optimize the construction plan, and help improve the construction efficiency. Slag, turning waste into treasure, energy saving and environmental protection.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a green building ready-mixed mortar and a green construction method thereof. Background technique [0002] Green building refers to the maximum saving of resources in the whole life cycle of the building, including energy saving, land saving, water saving, material saving, etc., to protect the environment and reduce pollution, to provide people with healthy, comfortable and efficient use of space, and to be in harmony with nature. Buildings that live in harmony. Green building technology focuses on low consumption, high efficiency, economy, environmental protection, integration and optimization. It is a benefit sharing between man and nature, present and future, and a means of sustainable development. [0003] At present, considering energy saving and environmental protection, many cities are gradually prohibiting on-site mixing of mortar and promoting the use of read...
