Graphene modified concrete retarder and preparation method thereof
The invention belongs to the technical field of concrete admixtures, and relates to graphene modified concrete retarder and a preparation method thereof. The retarder disclosed by the invention is prepared from the following components in parts by weight: 10 to 40 parts of graphene, 5 to 35 parts of ethylenediamine tetraacetic acid salt, 10 to 30 parts of formate, 10 to 35 parts of calcium bromideand 10 to 20 parts of urea. The retarder has the characteristics that the concrete setting time is delayed, the concrete strength increasing speed is increased, and the strength of concrete at all ages is improved.
本发明属于混凝土外加剂技术领域,涉及到一种石墨烯改性混凝土缓凝剂及其制备方法。本发明所述的缓凝剂组成包括:石墨烯10~40份、乙二胺四乙酸盐5~35份、甲酸盐10~30份、溴化钙10~35份、尿素10~20份。本发明具有在延缓混凝土凝结时间的同时,提升混凝土强度增长速度,提高混凝土各龄期强度的特点。
