Anti-crack recycled concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses anti-crack recycled concrete and a preparation method thereof. The anti-crack recycled concrete comprises the following components in parts by weight: 200-300 parts of cement; 200-300 parts of water; 200-300 parts of silica fume; 5-10 parts of a water reducing agent; 50-100 parts of an anti-crack composite fiber;600-700 parts of recycled coarse aggregate; 500-600 parts of recycled fine aggregate; 300-400 parts of sand; and 400-500 parts of fine stone. The preparation method comprises the following steps: mixing and uniformly stirring the recycled fine aggregate, the recycled coarse aggregate, the sand and the fine stone to obtain a mixture C; adding silica fume and anti-cracking composite fibers into themixture C, and continuously stirring the mixture to obtain a mixture D; and adding water, cement and a water reducing agent into the mixture D, and continuously stirring and mixing the mixture. The anti-crack recycled concrete and the preparation method thereof can be used for paving roadbeds and have the advantages of high crack resistance and the like.
本申请涉及混凝土技术领域，具体公开了一种抗裂再生混凝土及其制备方法。一种抗裂再生混凝土包括如下重量份数的组分：水泥200‑300份；水200‑300份；硅灰200‑300份；减水剂5‑10份；抗裂复合纤维50‑100份；再生粗骨料600‑700份；再生细骨料500‑600份；砂子300‑400份；细石400‑500份。其制备方法为：将再生细骨料、再生粗骨料、砂子、细石混合并搅拌均匀，得到混合物C；将硅灰、抗裂复合纤维加入混合物C中，继续搅拌，得到混合物D；向混合物D中加入水、水泥、减水剂，持续搅拌混合。本申请的抗裂再生混凝土及其制备方法可用于道路路基铺设，其具有抗裂性强等优点。
