Application of carboxylated nanocellulose in pervious concrete, pervious concrete and preparation method of pervious concrete
The invention belongs to the technical field of concrete, and particularly relates to application of carboxylated nanocellulose in pervious concrete, the pervious concrete and a preparation method of the pervious concrete. The hydroxylated nanocellulose is used in the pervious concrete, and the carboxylated nanocellulose can play a role of a nanocrystal nucleus, is beneficial to hydration of cement, and can improve the compressive strength and breaking strength of the pervious concrete so as to improve the crack resistance of the pervious concrete. Therefore, the pervious concrete provided by the invention is prepared from the following components in parts by mass: 0.9 to 1.1 parts of cement, 0.1 to 0.5 part of blast furnace slag, 0 to 0.4 part of fly ash, 0 to 0.05 part of silica fume, 0.0002 to 0.0026 part of carboxylated nano cellulose, 3.6 to 5.2 parts of coarse aggregate, 0 to 0.0002 part of an air entraining agent and 0.35 to 0.56 part of water. The pervious concrete provided by the invention has relatively high compressive strength and flexural strength.
本发明属于混凝土技术领域，具体涉及羧基化纳米纤维素在透水混凝土中的应用、一种透水混凝土及其制备方法。本发明将羟基化纳米纤维素用于透水混凝土中，羧基化纳米纤维素能够起到纳米晶核的作用，利于水泥的水化，能够提高透水混凝土的抗压强度和抗折强度从而提高透水混凝土的抗裂性能。由此，本申请提供了一种透水混凝土，包括以下质量份数的组分：0.9～1.1份水泥，0.1～0.5份高炉矿渣，0～0.4份粉煤灰，0～0.05份硅灰，0.0002～0.0026份羧基化纳米纤维素，3.6～5.2份粗骨料，0～0.0002份引气剂，0.35～0.56份水。本发明提供的透水混凝土具有较高的抗压强度和抗折强度。
