Abstract

The present invention relates to a building wall material, and discloses a deep foundation pit soil-sintered porous brick and a preparation method thereof. The deep foundation pit soil-sintered porous brick of the present invention is composed by the following raw materials by mass percentage: 30-50% of deep foundation pit soil; 20-40% of deep foundation pit soil dry powder; 20-30% of cinder; and 1-10% of an adobe regulator. The deep foundation pit soil-sintered porous brick of the present invention is good in mechanical properties and thermal insulation properties with strength up to MU20, and can be used as an ordinary load-bearing or non-load-bearing wall material.

Description

technical field [0001] The invention relates to a building wall material, in particular to a porous brick produced by using the waste soil produced by foundation pit excavation in urban infrastructure construction and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of urbanization, the generation of urban construction dregs has been increasing day by day. In Shanghai, there were 84 major projects in 2010, and the declared amount of construction dregs exceeded 46 million tons. In accordance with the principle of "protecting national land resources, realizing standardized disposal, and promoting recycling", Shanghai's construction waste disposal mainly includes the following types: one is low-lying land and backfilling of abandoned riversides, accounting for about 60%; the other is reclamation of land from the sea , accounting for about 20%; the third is about 15% for the production of recycled aggregates, roadbed materia...
