Lightweight aggregate concrete and preparation method thereof
The invention relates to the field of concrete materials, and discloses lightweight aggregate concrete which is prepared from cement, lightweight aggregate, an admixture, a dispersing agent, a thickening agent, a water reducing agent and water. The preparation method comprises the following steps: S1, adding water to soak the fly ash ceramsite and the clay ceramsite to obtain a pre-wetted aggregate, adding the cement and the desulfurized gypsum powder into the water, and mixing to obtain a cementing material; s2, putting the pre-wetted aggregate, machine-made sand and natural river sand into a jet mill for high-speed impact, and drying to obtain mixed aggregate; s3, adding a dispersing agent, a thickening agent, an admixture and an inactive admixture into the mixed aggregate prepared in the step S2, and stirring in a high-speed stirring section to obtain a uniformly mixed material; s4, adding a cementing material and a reducing agent into the homogenized material, and uniformly mixing to obtain a lightweight aggregate concrete finished product, the lightweight aggregate concrete can prevent the lightweight aggregate from floating upwards, improve the workability of a mixture, and improve the strength performance of the concrete.
本发明涉及混凝土材料领域，且公开了一种轻骨料混凝土，包括水泥、轻骨料、掺合料、分散剂、增稠剂、减水剂和水组成的原料；制备方法包括以下步骤：S1：加水对粉煤灰陶粒、黏土陶粒进行浸泡处理，得到预湿骨料，将水泥和脱硫石膏粉加入水中混合得到胶凝材料；S2：将预湿骨料和机制砂以及天然河砂置于气流粉碎机中高速撞击，干燥得到混合骨料；S3：之后向步骤S2制得的混合骨料加入分散剂、增稠剂以及掺和料和非活性掺合料，置于高速搅拌节中搅拌得到混匀质料；S4：之后向匀质料中加入胶凝材料和减少剂进行混合均匀，得到轻骨料混凝土成品，该发明的轻骨料混凝土能够防止轻骨料上浮，提高拌合物的和易性，以及提高混凝土的强度性能。
