Description

Aluminosilicate-containing composition

[0001] The present invention relates to an aluminosilicate-containing composition. More specifically, it relates to an aluminosilicate-containing composition useful for accelerating the hardening of a hydraulic material composition.

[0002] In the manufacturing process of ordinary Portland cement, a large amount of CO ２ is emitted. Therefore, a concrete composition in which cement is replaced with supplementary cementitious materials (Supplementary Cementitious Materials (SCM)) such as fly ash and slag has been proposed in order to reduce the emission of CO ２ Such SCM concrete has a longer setting time and has problems in early strength development compared to ordinary Portland cement (OPC).

[0003] Regarding the technology for improving the early strength of concrete, Patent Document 1 discloses an aluminosilicate-containing composition containing an aluminosilicate and a water-soluble polymer, wherein the aluminosilicate has an average particle diameter measured by a predetermined measurement method of 10 to 2500 nm. Patent Document 2 discloses a polycarboxylic acid-based copolymer obtained by polymerizing a monomer component containing an unsaturated polyalkylene glycol-based monomer represented by a predetermined formula and an unsaturated carboxylic acid-based monomer represented by a predetermined formula. Patent Document 3 discloses a cement hardening accelerator composition containing two or more alkanolamine-based compounds and a cement dispersant, wherein the two or more alkanolamine-based compounds include triethanolamine and triisopropanolamine, and the mass ratio of triethanolamine to triisopropanolamine is triethanolamine / triisopropanolamine = 10 to 90 / 90 to 10.
