Paving brick and preparation method thereof
The invention discloses a paving brick and a preparation method thereof, and relates to the technical field of building materials. The paving brick comprises 50-65 parts by weight of engineering spoil, 8-16 parts by weight of an alkali activator, 12-25 parts by weight of a mineral admixture, 1-2 parts by weight of a water reducer, and 10-20 parts by weight of water. The preparation method comprises the steps of: mixing the alkali activator and the mineral admixture, and stirring to a gelling state to obtain a gel mixture; adding the engineering spoil, the water reducer and the water into the gel mixture, and stirring to a semi-dry state to obtain a mixture; and pouring the mixture into a mold, pressing and vibrating for 5-10 seconds, and performing curing and demolding to obtain the paving brick. The problem that in the prior art, the engineering spoil is high in treatment cost and cannot be effectively recycled is solved. The paving brick is manufactured by using the engineering spoil as a main component, the manufactured paving brick has the effects of being high in compression resistance and breaking strength and good in quality, and meanwhile, the paving brick has the advantages of being simple in preparation method and low in cost.
本发明公开了一种铺路砖及其制备方法，涉及建材技术领域，铺路砖包括：50～65重量份的工程弃土、8～16重量份的碱激发剂、12～25重量份的矿物掺和料、1～2重量份的减水剂、10～20重量份的水；制备方法包括：将碱激发剂和矿物掺和料进行混合，并搅拌至胶凝状态，获得胶凝混合物；在胶凝混合物中加入工程弃土、减水剂和水，并搅拌至半干状态，获得拌合物；将拌合物倒入模具中，压振5～10秒，进行养护和脱模，制得铺路砖。本发明解决了现有技术中工程弃土处理成本高，不能有效再利用的问题，实现了利用工程弃土作为主要成分制作铺路砖，且制得的铺路砖的抗压和抗折强度较高、质量较好的效果，同时还具有制备方法简单，成本低的优点。
