Waste-utilizing X-shaped hollow or composite energy-saving building block
The invention discloses a waste-utilizing X-shaped hollow or composite energy-saving building block. A base body of the hollow energy-saving building block is formed by grading and mixing solid waste such as pulverized coal ash, furnace slag and building waste and cement according to a certain proportion and then pressing. Internal ribbed frames are in X-shaped diagonal arrangement and divide an internal cavity into four triangular cavities similar in size, and optimal hole ratio is 50-60%, so that heat insulativity of the building block and stressed performance of a block body are improved. Nonuniformity of a heat path of the building block is low, so that cold-heat bridge is reduced; when no heat-insulating material is composited, energy saving effect of the building block is higher than common building blocks by 20%; after the heat-insulating material is composited in two closed holes, the energy saving effect of the building block is higher than the common building blocks by 55%; if the heat-insulating material needs to be composited in all holes, the energy saving effect of the building block may be higher than the common building blocks by 80%, heating energy consumption can be saved by 50-80% in different areas, and energy-saving designing standard requirements can be met without taking other heat-insulating measures to a built wall.
