引用本文摘 要：傳統再生細骨料需水量大、強度低，較難利用，將廢棄混凝土全部破碎成細骨料的全再生細骨料技術能有效提高再生細骨料性能。在前期研究基礎上，進行了全再生細骨料對砂漿性能影響的研究。結果表明，在同樣砂漿稠度的情況下，全再生細骨料砂漿的綜合性能優于傳統再生細骨料砂漿，與機制砂砂漿和河砂砂漿相近，可全取代機制砂或河砂用于制備砂漿；全再生細骨料具有較好的保水性能，用其配制砂漿時可較河砂和機制砂適當降低保水劑用量。 Abstract: The tranditional recycled fine aggregates has large water demand, low strength, and difficult to use, all recycled fine aggregate technology that is brocken waste concrete into fine aggregatecan, improve the performance of recycled fine aggregate. Based on the previous research, the influence of all recycled fine aggregate on mortar performance is studied. The results show that under the condition of the same mortar consistency, the comprehensive performance of the all recycled fine aggregate mortar is superior to the traditional recycled fine aggregate mortar, which is similar with manufactured-sand mortar and river sand mortar, all recycled fine aggregate mortar can fully replace the manufactured-sand mortar or river sand to prepare mortar. The all recycled fine aggregate has good water retention performance, the dosage of aquasorb can be appropriatly decreased for preparing mortar by using all recycled fine aggregate, compared with river sand and manufatured sand.
