Preparation method of hollow self-insulation building block
The invention discloses a preparation method of a hollow self-insulation building block, belonging to the fields of waste utilization and preparation of inorganic non-metallic materials. According tothe invention, cement is used as a main raw material, and straw fibers and fly ash are used as modification admixtures; the prepared hollow self-insulation building block is low in heat conductivity coefficient and good in insulation effect; low-carbon reutilization of straw is realized, and regional climate, environmental adaptability and energy efficiency of a building are improved; and the straw fibers are loose and low in heat conductivity coefficient, and the straw fibers are recycled to serve as a modification material and added into a fly ash building block, so the problems of environmental pollution and resource wasting caused by burning of straw outdoors can be solved, the use amount of cement can be reduced, the porosity of the building block is improved, and the density and theheat conductivity coefficient of the building block are reduced.
本发明公开了一种空心自保温砌块制备方法，涉及废弃物利用及无机非金属材料制备领域，本发明以水泥为主要原料，用秸秆纤维和粉煤灰作为改性掺合料，制备导热系数低、保温效果好的空心自保温砌块，实现秸秆的低碳再利用，提高建筑的区域气候、环境适应性和能效；秸秆纤维本身疏松且导热系数低，将其资源化作为改性材料加入粉煤灰砌块不仅可以解决秸秆露天焚烧污染环境、浪费资源的问题，而且可降低水泥的用量，提高砌块的孔隙率，降低砌块的密度和导热系数。
