Concrete block and preparation method thereof
The invention relates to a concrete block and a preparation method thereof. The preparation method comprises the following steps: 1) crushing and screening corn straws to obtain first corncobs; 2) carrying out slurry wrapping treatment on the first corncob, and standing to obtain a second corncob; and 3) replacing part of the aggregate with the second corncob to prepare concrete, and preparing the concrete block. The technical problem to be solved by the invention is how to digest and utilize the corn straw, so that the corn straw can be turned into wealth and recycled, the heat insulation and heat preservation properties of the concrete block can be improved, the water absorption rate of the concrete block can be reduced, and the strength and other properties of the concrete block can be improved, so that the concrete block is more practical.
本发明是关于一种混凝土砌块及制备方法。所述制备方法包括以下步骤：1)玉米秸秆破碎筛分，得第一玉米芯；2)将所述第一玉米芯裹浆处理，静置，得第二玉米芯；3)以所述第二玉米芯替代部分骨料配制混凝土，制成混凝土砌块。本发明所要解决的技术问题是如何消化利用玉米秸秆，既能使玉米秸秆变废为宝，得到资源化利用，又能提高混凝土砌块的隔热、保温性能，同时还能降低混凝土砌块的吸水率和提高混凝土砌块的强度等性能，从而更加适于实用。
