Filling material

Abstract

The invention provides a filling material for walls and floors. Semi-hydrated gypsum is used as a rapid-hardening material. Dihydrate gypsum is used as a slow-hardening material. The filling material can be hardened fast, improves efficiency and guarantees construction operation time. Because of batch industrial production, filling material requirements are reduced, the raw materials have wide sources, a cost is reduced, and local materials and industrial, agricultural and building waste are fully used, and thus a material physical-distribution cost is greatly reduced and environmental protection, cyclic economy development and sustainable development are promoted. Through rapid-hardening filling material use, a construction tool can be timely dismounted and recycled. Through centralized configuration of a semi-finished product mixture and on-site re-addition of functional materials, core rapid-hardening is realized, pipe blocking is avoided, an equipment cleaning process is avoided, labor is saved, and efficiency is improved. Through whole mechanization from blending to pouring, labor is greatly saved, efficiency is improved and a cost is reduced.

Description

technical field [0001] The invention relates to a filling material for building filling walls or floors, in particular to the composition and ratio of the filling material. Background technique [0002] Building infill walls and floor slabs are the maintenance structures of buildings. They are large in quantity and wide in area. Their performances such as sound insulation, heat insulation, strength, fire prevention, moisture resistance, and water resistance directly affect the usability and safety performance of buildings. With the progress of the times and the requirements of environmental protection, the era of Qin bricks and Han tiles has come to an end, and new wall materials have been introduced continuously. broadly used. [0003] However, the above-mentioned filling walls also have the following problems: First, with the shortage of human resources in our country, labor costs have doubled, logistics costs have continued to increase, and the cost of filling walls has ...

Problems solved by technology

[0003] However, the above-mentioned filling walls also have the following problems: First, with the shortage of human resources in our country, labor costs have doubled, logistics costs have continued to increase, and the cost of filling walls has increased significantly; secondly, traditional floor slabs generally Reinforced concrete thin slabs of 80-100mm have poor sound insulation and energy-saving performance, and no partition wall can be placed on it, which limits the flexibility of use; in addition, the strength of the aerated concrete block filled wall is low It is not conducive to safety and painting, and its heavy weight will increase the cost of the main structure. The poor integrity is not conducive to the earthquake resistance of the structure, and the construction process of the hollow inner mold metal mesh cement inner partition wall is complicated, which makes the construction period correspondingly longer

However, hemihydrate gypsum has a relatively large defect as a filling material for filling walls. The main reason is that it solidifies quickly, usually within 3 to 5 minutes. Such a short period of time is impossible for large-scale and large-area construction. Because the material has solidified before pouring is complete.

Although a synthetic retarder can be added to delay the time, the price of the retarder itself is very high, and the configuration is also troublesome. If it is used in large quantities, the cost will inevitably increase significantly
