Underwater non-dispersible concrete and preparation process thereof
The invention relates to the technical field of concrete materials, and particularly discloses underwater non-dispersible concrete and a preparation technology thereof.The underwater non-dispersible concrete is prepared from cement, a mineral admixture, coarse aggregate, fine aggregate, a water reducing agent, an early strength agent, a retarder, water, an anti-dispersing agent and composite fibers; the anti-dispersing agent mainly comprises polyacrylate, vinyl neodecanoate and pentasodium diethylene triamine pentaacetate; the preparation process comprises the following steps: mixing the cement, the early strength agent, the retarder and the anti-dispersing agent with the composite fiber to obtain a mixture A; mixing the coarse aggregate, the fine aggregate and the mineral admixture to obtain a mixture B; and mixing the mixture A with the mixture B, then mixing the water reducing agent with water, adding the mixture, and stirring to obtain the underwater non-dispersible concrete. The underwater non-dispersible concrete has the characteristic of improving the dispersion resistance and compressive strength of the underwater non-dispersible concrete.
本申请涉及混凝土材料技术领域，具体公开了一种水下不分散混凝土及其制备工艺，水下不分散混凝土包括以下原料：水泥、矿物掺合料、粗骨料、细骨料、减水剂、早强剂、缓凝剂、水、抗分散剂和复合纤维，所述抗分散剂主要包括聚丙烯酸酯、新癸酸乙烯酯和二亚乙基三胺五乙酸五钠；其制备工艺包括以下步骤：将水泥、早强剂、缓凝剂和抗分散剂与复合纤维混合，得到混合物A；将粗骨料和细骨料以及矿物掺合料混合，得到混合物B；将混合物A和混合物B混合，然后将减水剂与水混合后加入，拌合，得到水下不分散混凝土。本申请具有提高水下不分散混凝土的抗分散性以及抗压强度的特点。
