Abstract

The invention discloses a green construction method of pre-mixed mortar for building construction. The method comprises the steps of preparing the pre-mixed mortar; carrying out material absorption; transporting the pre-mixed mortar; arranging a cooling circulation pipe network; carrying construction of the pre-mixed mortar: (1) carrying out primary construction of the pre-mixed mortar; (2) building a water storage thermal insulation curing pool; (3) monitoring the temperature in real time; (4) carrying out secondary construction of the pre-mixed mortar; (5) blocking a cooling circulation pipe network, recovering waste water in the water storage thermal insulation curing pool, and the like. The pre-mixed mortar is reasonable in component collocation; the prepared pre-mixed mortar is better in adhesion force and adaptability of temperature difference and good in color, does not easily crack, has very high hydrophobic property, heat insulation property, heat preservation property, and the like, and can be molded at a time during construction. The construction method provided by the invention realizes a construction scheme integrating mortar production, detection, transporting, pouring, remote optimization and real-time management, thus reducing constructors, lightening the labor intensity, improving the construction quality, increasing the construction efficiency, and lowering the engineering cost; therefore, the construction method has good popularization and application value.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a green construction method of ready-mixed mortar for building construction. Background technique [0002] In 2007, the Ministry of Commerce, the Ministry of Public Security, the Ministry of Construction, the General Administration of Quality Supervision, Inspection and Quarantine, and the State Environmental Protection Administration issued the "Notice on Prohibiting On-Site Mixing of Mortar in Some Cities within a Time Limit" (Shang Gaifa [2007] No. 205), and Guangzhou was the first batch Cities that banned on-site mixing of mortar within a limited period began to promote the use of ready-mixed mortar in 2008, but the effect was not satisfactory. The main reason is that there are defects in the two ready-mixed mortars currently used: the wet-mixed mortar is limited by the time limit of use, and the dry-mixed mortar has segregation and dust during the distribution ...
