Abstract
A cementitious composition comprises cement and crystalline cellulose or nanocrystalline cellulose formed from a cellulosic material by a redox reaction.
Claims17
A cement composition comprising cement and crystalline cellulose formed by a redox reaction and which are substantially pure cellulose nanocrystals (CNCs) which are substantially free of all mono-, di- and oligosaccharides.
A cement composition comprising cement and crystalline cellulose which has been treated with an alkaline solution to remove mono-, di- and oligosaccharides.
A method of forming a cement composition, comprising the steps of:
- (a) producing crystalline cellulose nanocrystals (CNCs) by oxidizing a cellulosic material;
- (b) washing the CNCs with an alkaline solution to form substantially pure CNCs substantially free of mono-, di- and oligosaccharides;
- and
- (c) mixing the CNCs with cement.
