REINFORCED CONCRETE INTERNAL CURING HIGH-WATER-ABSORPTION MICROSPHERE MATERIAL AND PREPARATION METHOD THEREFOR

摘要

Disclosed are a reinforced concrete internal curing high-water-absorption microsphere material and a preparation method therefor. The microsphere material is prepared from the following raw materials: nano silica, chitosan, glutaraldehyde, arabic gum, methacrylic acid, glacial acetic acid, isopropyl benzene hydroperoxide, ferrous chloride and sodium ethoxide. Same modifies the microstructure inside a cement-based material by improving a transition region between a cement paste and an aggregate, whereby the porosity is reduced and the mechanical properties are improved.
