Foamed concrete and preparation process thereof
The foamed concrete is prepared from the following components in parts by mass: 90 to 120 parts of cement, 120 to 160 parts of gravel, 0.5 to 0.7 part of a water reducing agent, 42 to 48 parts of water, 12 to 14 parts of a foaming agent, 0.5 to 0.7 part of a water reducing agent, 18 to 22 parts of modified basalt chopped fibers and 3 to 5 parts of bentonite microcapsules, the modified basalt chopped fibers are prepared by the following method: S1, heating basalt chopped fibers, soaking the basalt chopped fibers in tetrachloroethylene, cooling the basalt chopped fibers, and washing the basalt chopped fibers to obtain prefabricated basalt chopped fibers; and S2, adding a silane coupling agent solution into the prefabricated basalt chopped fibers in the step S1, soaking, and drying to obtain the modified basalt chopped fibers. The effect of improving the mechanical property of the concrete is achieved.
本申请涉及一种发泡混凝土，其包括如下质量分的组分：水泥90‑120份、砂石120‑160份、减水剂0.5‑0.7份、水42‑48份、发泡剂12‑14份、减水剂0.5‑0.7份、改性玄武岩短切纤维18‑22份、膨润土微胶囊3‑5份；所述改性玄武岩短切纤维采用如下方法制备而成：S1、将玄武岩短切纤维加热后，浸泡至四氯乙烯中，冷却后对玄武岩短切纤维洗涤，得到预制玄武岩短切纤维；S2、将硅烷偶联剂溶液溶液加入步骤S1中的预制玄武岩短切纤维，浸泡后干燥，即可得到改性玄武岩短切纤维。本申请具有提升混凝土力学性能的效果。
