High-strength anti-crack concrete and preparation process thereof
The invention relates to the field of concrete, and particularly discloses high-strength anti-crack concrete and a preparation process thereof. The high-strength anti-crack concrete is prepared from water, cement, recycled coarse aggregate, recycled fine aggregate, fly ash and an additive. The additive comprises 4.85-8 parts of a polycarboxylate superplasticizer, 0.8-1.6 parts of pentabromoethyl benzene, and 0.5-1.3 parts of DTPMP.Nax. The preparation method comprises the following steps: step 1, stirring the recycled fine aggregate, the cement, the fly ash and the additive together to obtaina first prepared material; step 2, adding water into the first prepared material, and performing stirring to obtain a second prepared material; and step 3, adding the recycled coarse aggregate into the second prepared material, and performing stirring to obtain the high-strength anti-crack concrete. The high-strength anti-crack concrete disclosed by the invention can be used in infrastructure construction and has the advantages of excellent anti-crack strength and compressive strength; and in addition, the preparation method disclosed by the invention has the advantage that the concrete has better crack resistance and compressive strength.
本申请涉及混凝土领域，具体公开了一种高强度抗裂混凝土及其制备工艺。高强度抗裂混凝土包括：水、水泥、再生粗骨料、再生细骨料、粉煤灰、外加剂；外加剂包括：聚羧酸高效减水剂4.85~8份；五溴乙基苯0.8~1.6份；二乙烯三胺五甲叉膦酸钠0.5~1.3份。其制备方法为：步骤1，将再生细骨料、水泥、粉煤灰和外加剂一起搅拌获得第一备料；步骤2，将水加入第一备料中搅拌，获得第二备料；步骤3，将再生粗骨料加入第二备料中搅拌，获得高强度抗裂混凝土。本申请的高强度抗裂混凝土可用于基建中，其具有优异的抗裂强度和抗压强度的优点；另外，本申请的制备方法具有使混凝土抗裂强度和抗压强度更好的优点。
