The invention relates to the field of environment-friendly concrete, in particular to environment-friendly concrete for road paving and a preparation method of the environment-friendly concrete. The invention discloses environment-friendly concrete for road paving. The environment-friendly concrete is prepared from the following raw materials: Portland cement, a mineral admixture, water, fine aggregate, recycled coarse aggregate, coal gangue, calcium-aluminum hydrotalcite, coconut oil and an additive, the preparation method comprises the following steps: uniformly mixing the recycled coarse aggregate and the fine aggregate to obtain mixed aggregate; adding Portland cement, a mineral admixture, coal gangue, calcium-aluminum hydrotalcite, coconut oil and water into the mixed aggregate, and uniformly mixing to obtain a mixture; and then adding the additive, and uniformly mixing to obtain the environment-friendly concrete. The method has the advantage that the strength of the concrete using the recycled coarse aggregate is improved.
本申请涉及环保混凝土领域，更具体地说，它涉及用于道路铺设的环保混凝土及其制备方法。一种用于道路铺设的环保混凝土，包括以下原料：硅酸盐水泥、矿物掺合料、水、细骨料、再生粗骨料、煤矸石、钙铝水滑石、椰子油、外加剂；其制备方法为：将再生粗骨料、细骨料混合均匀，得到混合骨料；往混合骨料中加入硅酸盐水泥、矿物掺合料、煤矸石、钙铝水滑石、椰子油、水，混合均匀得到拌合料；然后再加入外加剂，混合均匀后得到环保混凝土。本申请具有提高使用再生粗骨料的混凝土的强度的优点。
