Concrete internal curing micro-ceramsite and preparation method thereof
The invention discloses a concrete internal curing micro-ceramsite and a preparation method thereof. The internal curing micro-ceramsite comprises the following components in parts by weight: 20-40 parts of glass powder, 40-70 parts of sinking beads, 10-20 parts of silica fume, 1-2 parts of a foaming agent and 1-2 parts of a reinforcing agent. The invention also discloses a preparation method of the concrete internal curing micro-ceramsite, which comprises the following steps: stirring the raw materials of glass powder, sinking beads and silica fume to prepare slurry, adding a foaming agent and a reinforcing agent, carrying out shear foaming, preparing a micro-ceramsite blank by a spray drying method, and sintering by a stacking sintering method to obtain the concrete internal curing micro-ceramsite. The internal curing micro-ceramsite is small in particle size, provided with holes in the surface and controllable in hole structure. The micro-ceramsite prepared by the method has the advantages of small particle size, controllable size, high water absorption, high strength and the like, and the method is suitable for various material systems.
本发明公开了一种混凝土内养护微陶粒及其制备方法。内养护微陶粒组成包括玻璃粉20~40重量份、沉珠40~70重量份、硅灰10~20重量份、发泡剂1~2重量份、增强剂1~2重量份。本发明同时公开了一种混凝土内养护微陶粒的制备方法，首先采用玻璃粉、沉珠、硅灰为原材料经搅拌制备成浆体，加入发泡剂和增强剂后进行剪切发泡，通过喷雾干燥法制备微陶粒坯体，随后采用堆烧法进行烧结，得到粒径小、表面开孔且孔结构可控的内养护微陶粒。本方法制备的微陶粒具有粒径小、尺寸可控、吸水率高、强度高等优点，且该方法适用于多种材料体系。
