Early-strength self-compacting concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses early-strength self-compacting concrete and a preparation method thereof. The early strength type self-compacting concrete is prepared from the following components in parts by weight: 360 to 400 parts of cement, 550 to 590 parts of coarse aggregate, 560 to 600 parts of sand, 110 to 150 parts of admixture, 24 to 32 parts of additive, 150 to 180 parts of water and 100 to 140 parts of adsorbent, and the adsorbent is prepared from carboxyl functional acrylate emulsion, beet pulp fiber and adsorption powder, the weight ratio of the carboxyl functional acrylate resin to the beet pulp fiber to the adsorption powder is (2-3): (2-3): 1. The early-strength self-compacting concrete can be used for pouring a mass concrete structure body, and has the advantages that the damage to the mass concrete structure body is reduced, so that the influence on the strength of the mass concrete is reduced.
本申请涉及混凝土领域，具体公开了一种早强型自密实混凝土及其制备方法。一种早强型自密实混凝土包括以下重量份的组分：水泥360～400份，粗骨料550～590份，砂560～600份，掺和料110～150份，外加剂24～32份，水150～180份，吸附剂100～140份，所述吸附剂包括羧基官能丙烯酸酯乳液、甜菜粕纤维和吸附粉料，所述羧基官能丙烯酸酯树脂、甜菜粕纤维和吸附粉料三者重量之比为2～3:2～3:1。本申请的早强型自密实混凝土可用于大体积混凝土结构体浇筑，其具有减少大体积混凝土结构体被破坏，从而降低对大体积混凝土强度的影响的优点。
