High-strength recycled concrete and preparation method thereof
The invention discloses high-strength recycled concrete which comprises recycled concrete coarse aggregate, recycled concrete fine aggregate, cement and a foaming agent, wherein the foaming agent comprises lauryl sodium sulfate, sodium dodecyl benzene sulfonate, a betaine type surfactant, stearic acid and polyvinyl alcohol. The invention further discloses a preparation method of the high-strength recycled concrete. The preparation method comprises the steps: step 1, firstly, treating waste concrete blocks; step 2, according to the weight ratio, taking the recycled concrete coarse aggregate, the recycled concrete fine aggregate and one part of water to prepare slurry, adding the foaming agent into the other part of water to form foaming liquid, and then mixing the slurry and the foaming liquid for reaction; and step 3, preparing to obtain the recycled concrete. The concrete with high compressive strength and water seepage resistance can be prepared.
本发明公开了高强度再生混凝土，包括：再生混凝土粗集料，再生混凝土细集料，水泥和发泡剂，发泡剂包括：十二烷基硫酸钠、十二烷基苯磺酸钠、甜菜碱型表面活性剂、硬脂酸和聚乙烯醇。本发明还公开了高强度再生混凝土的制备方法，包括：步骤一、首先将废弃混凝土块处理；步骤二、按照重量比，取所述再生混凝土粗集料、再生混凝土细集料和一部分水制成泥浆，同时将发泡剂加入另一部分水中形成发泡液，之后将二者混合反应；步骤三、制备得到再生混凝土。本发明能够制备得到抗压强度和抗渗水能力强的混凝土。
