Embodiment 1
[0012] Such as figure 1 figure 2 As shown, the large-volume fly ash composite self-insulating block of the present invention includes a rectangular block body 2 with eight through holes 1 formed by extrusion, and the through holes are arranged in three rows up and down, parallel and staggered. Wherein the first row and the third row are the same, all are three rectangular longitudinal through holes, the second row is two rectangular longitudinal through holes plus two longitudinal semi-open through holes, and each row of holes has a hole wall interval. The left and right sides of the rectangular block body 2 are symmetrically opened with semi-open through-holes 3 , and thermal insulation materials 4 are filled in the semi-open through-holes 3 and the plurality of through-holes 1 .
[0013] The preparation method of the large-volume fly ash composite self-insulating block of the present invention: firstly, fly ash, Portland cement, and fly ash ceramsite are crushed in a rolle...
Embodiment 2
[0015] Such as figure 1 figure 2 As shown, while extruding a rectangular block body with eight through holes, semi-open through holes are symmetrically extruded on its left and right sides. The cross section of the through holes is rectangular. The first row and the third row are the same, all are three rectangular longitudinal through holes, the second row is two rectangular longitudinal through holes plus two longitudinal semi-open through holes, and each row of holes has a hole wall interval. The semi-open through hole and multiple through holes are filled with insulation material mixed with rice husk, Portland cement and 901 glue according to the mass percentage, compacted, leveled, and prepared after natural curing.
[0016] Preparation method of large-volume fly ash composite self-insulating block: by mass percentage, the fly ash is 43.4%, Portland cement is 16.9%, fly ash ceramsite is 33.9%, and water is 5.8% . Filling material preparation method: In terms of mass p...
Embodiment 3
[0018] Such as figure 1 figure 2 As shown, while extruding a rectangular block body with eight through holes, semi-open through holes are symmetrically extruded on its left and right sides. The cross section of the through holes is rectangular. Wherein the first row and the third row are the same, all are three rectangular longitudinal through holes, the second row is two rectangular longitudinal through holes plus two longitudinal semi-open through holes, and each row of holes has a hole wall interval. The semi-open through hole and multiple through holes are filled with insulation material mixed with rice husk, Portland cement and 901 glue according to the mass percentage, compacted, leveled, and prepared after natural curing. The cycle of natural conservation is about 28 days. Care should be taken to keep the blocks moist during maintenance, especially in dry and hot climates, to prevent cracks on the surface of the blocks.
