Preparation method of concrete road brick
The invention discloses a preparation method of a concrete road brick, which comprises the following steps: firstly recycled straws are soaked in an acid solution, then steps of filtering, washing with water, then soaking in an alkaline solution are carried out, then the material is subjected to filtering, drying and crushing to be less than or equal to 2.5 cm to obtain a straw material, the construction waste recycled aggregate powder, the straw material, calcium chloride, sand, cement, a water reducing agent, waste rubber particles, a gelling agent and water are added into a stirring machine to be mixed and stirred to be uniform, and then the stirred mixed material is loaded into a concrete pavement brick mold to be subjected to vibration hot-pressing curing forming; the formed pavement brick blank is subjected to steam curing, in the first stage, the constant-temperature curing temperature is 40-50 DEG C, and the curing time is 3-5 h; the second-stage constant-temperature curing temperature is 55-65 DEG C, the curing time is 2-4 hours, the third-stage constant-temperature curing temperature is 40-45 DEG C, and the and then natural curing is carried out for 6-10 days, water is sprayed for 3 times every day, and then calcining is carried out at 160-200 DEG C for 3-6 hours to obtain the road brick.
本发明公开了一种混凝土路砖的制备方法，包括将回收来的秸秆首先浸泡在酸性溶液中，然后过滤用水进行洗涤，再浸泡在碱性溶液中，然后将其过滤，干燥，粉碎成小于或等于2.5cm，得到秸秆料，将建筑物垃圾再生骨料粉、秸秆料、氯化钙、沙子、水泥、减水剂、废旧橡胶颗粒、胶凝剂和水加入到搅拌机中进行混合搅拌均匀，然后将搅拌好的混合物料装入混凝土路面砖模具中振动热压固化成型；将成型后的路面砖坯体进行蒸汽养护，第一阶段恒温养护温度为40～50℃，养护时间为3～5h；第二阶段恒温养护时间为55～65℃，养护时间为2～4h，第三阶段恒温养护温度为40～45℃，养护时间为2～3h；然后进行自然养护6～10天，每天喷洒3次水，然后在160～200℃下煅烧3～6h，得到路砖。
