Abstract

The invention relates to the technical field of solid waste recycling and fabricated buildings, and provides a solid waste large-mixing-amount concrete prefabricated laminated slab and a preparation method thereof. The solid waste large-mixing-amount concrete prefabricated laminated slab comprises a prefabricated layer and a laminated layer, transverse grooves and longitudinal grooves are formed in the surface of the prefabricated layer, during application, the grooves can be used for erecting pipelines, the contact area of the prefabricated layer and the laminated layer can also be increased, the combination effect of new concrete and old concrete is improved, the integrity of a floor slab is enhanced, and the effect of improving the overall stress capacity of the floor slab is achieved. The prefabricated laminated slab is prepared from the solid waste large-mixing-amount concrete, efficient utilization of solid waste resources is realized, a new absorption channel is provided for industrial solid wastes, the environmental protection pressure is relieved, and the double-industry fusion of two industries, namely the prefabricated buildings and solid waste recycling, in technology, management and industry chains is realized.

Description

technical field

[0001] The invention relates to the technical field of solid waste recycling and prefabricated buildings, in particular to a prefabricated laminated concrete slab with a large amount of solid waste and a preparation method thereof. Background technique

[0002] For many years, China's sand and gravel aggregates have been mostly collected naturally, and the phenomenon of random mining and indiscriminate excavation is relatively prominent, which has a great impact on the ecological environment. The existing prefabricated laminated panels are mainly prepared by using natural sandstone aggregate and cement as the main raw materials. With the development of the times, China's economy has shifted from a stage of high-speed growth to a stage of high-quality development, and more attention has been paid to the sustainable development of "green water and green mountains". Natural sand and gravel aggregate resources are becoming increasingly scarce, and the price cont...
