Slurry-coated recycled aggregate and preparation method thereof
The invention belongs to the technical field of building materials, and provides slurry-coated recycled aggregate and a preparation method thereof, and the preparation method comprises the following preparation steps: step 1, weighing according to parts by weight, adding silicon dioxide and graphene oxide dispersion liquid into water which is half of the required water, and stirring for 5-15 minutes to prepare a uniform solution; 2, cement and fly ash are mixed and stirred for 60-120 s, and a uniform composite adhesive material is prepared; step 3, adding the solution prepared in the step 1 into the composite adhesive material prepared in the step 2, then adding the rest half of water, and stirring for 60-120 seconds to prepare a wrapping sizing agent; step 4, pouring the wrapping slurry prepared in the step 3 into the recycled aggregate, and uniformly stirring; and step 5, tiling and airing the recycled aggregate treated in the step 4 to obtain the slurry-coated recycled aggregate. The coating slurry provided by the invention can effectively enhance various properties of the recycled aggregate, and significantly improves the compressive strength of the recycled concrete.
本发明属于建筑材料技术领域，提供了一种裹浆再生骨料及其制备方法，包括以下制备步骤：步骤1、按重量份称取，将二氧化硅与氧化石墨烯分散液加入所需用水一半用量的水，搅拌5～15min，制成均匀的溶液；步骤2、将水泥与粉煤灰混合，搅拌60～120s制成均匀的复合胶材；步骤3、将步骤1中制成的溶液加入步骤2中制成的复合胶材中，再加入剩下的一半水，搅拌60～120s制成裹浆料；步骤4、将步骤3中制得的裹浆料倒入再生骨料中，搅拌均匀；步骤5、将步骤4中处理后的再生骨料平铺晾干，得到裹浆再生骨料。本发明提供的裹浆料可以有效地增强再生骨料各项性能，显著提升了再生混凝土的抗压强度。
