Pervious concrete prepared from foam concrete waste
The invention relates to the field of building materials, and particularly discloses pervious concrete prepared from foam concrete waste, and the pervious concrete is prepared from the following raw materials in parts by weight: 10-30 parts of cement, 0-50 parts of coarse aggregate, 10-50 parts of modified regenerated foam concrete particles, 10-30 parts of water, 13-27 parts of styrene-butadiene emulsion, 7-15 parts of silica fume and 0.5-1 part of an additive, the modified regenerated foam concrete particles are prepared by modifying foam concrete waste with a silane modifier. According to the pervious concrete, all the components cooperate with one another, the obtained pervious concrete is high in pervious rate and good in compressive strength, and the water absorption rate and the freeze-thaw loss rate of the pervious concrete can be reduced.
本申请涉及建筑材料领域，具体公开了一种泡沫混凝土废料制备的透水混凝土，透水混凝土由包含以下重量份的原料制成：水泥10‑30份、粗骨料0‑50份、改性再生泡沫混凝土颗粒10‑50份、水10‑30份、丁苯乳液13‑27份、硅灰7‑15份和外加剂0.5‑1份；所述改性再生泡沫混凝土颗粒由硅烷改性剂对泡沫混凝土废料改性制得。本申请中的各组分相互配合，得到的透水混凝土透水率高且抗压强度好，且可减少透水混凝土的吸水率和冻融损失率。
