Green high-strength and high-toughness concrete and preparation process thereof
The invention relates to the field of concrete, and particularly discloses green high-strength and high-toughness concrete and a preparation process thereof. The green high-strength and high-toughness concrete is prepared from the following raw materials in parts by weight: cement, fly ash, mineral powder, natural aggregate, modified regenerated aggregate, water, an additive and composite fibers, a preparation method of the modified regenerated aggregate comprises the following steps: weighing waste concrete blocks, pretreating to obtain regenerated aggregate, putting the regenerated aggregate into a sodium gluconate solution, stirring and soaking, then taking out the regenerated aggregate, and performing drying post-treatment to obtain the modified regenerated aggregate; the preparation method comprises the following steps: weighing the cement, the fly ash and the mineral powder, mixing and stirring to obtain a premix; weighing the natural aggregate, the modified regenerated aggregate and the composite fiber, stirring and mixing to obtain a mixture; weighing the water, the additive, the premix and the mixture, mixing and stirring to obtain a mixture, and pouring and curing to obtain the concrete, the concrete has the advantages of greenness, high strength and high toughness.
本申请涉及混凝土领域，具体公开了一种绿色高强韧性混凝土及其制备工艺；一种绿色高强韧性混凝土由包含以下重量份的原料制成：水泥、粉煤灰、矿粉、天然集料、改性再生集料、水、外加剂、复合纤维；改性再生集料制备方法如下：称取废旧混凝土块经预处理制得再生集料，再生集料置于葡萄糖酸钠溶液中搅拌浸泡，然后取出再生集料，经干燥后处理，制得改性再生集料；其制备方法为：称取水泥、粉煤灰、矿粉混合搅拌制得预混料；称取天然集料、改性再生集料、复合纤维搅拌混合制得混合料；称取水、外加剂与预混料和混合料混合搅拌，制得拌和料，经浇筑、养护，制得混凝土；使混凝土同时具有绿色、高强、高韧性的优点。
