AI Technical Summary

Technical Problem

Existing construction materials, such as cement, contribute significantly to carbon emissions and do not achieve high strength without compromising durability when exposed to air or water.

Method used

A cured body is produced by mixing a powder component containing slaked lime, cement, and aggregate with a liquid component of glycerol carbonate and dimethyl carbonate, utilizing their reactions to form calcium carbonate, enhancing strength and reducing cement usage.

Benefits of technology

The method results in a high-strength cured body that minimizes carbon emissions and maintains strength in both air and water environments, addressing the limitations of conventional materials.

Abstract

To provide a cured body which contributes to low carbonization, can achieve high strength and can suppress reduction in strength especially in both cases when left in air and in water.SOLUTION: There is provided a cured body obtained by mixing and curing a powder and a liquid. The powder includes a slaked lime, cement and an aggregate. The liquid includes glycerol carbonate and dimethyl carbonate. The total content of the glycerol carbonate and dimethyl carbonate preferably is larger than 70 pts.mass based on 100 pts.mass of the slaked lime. The content of the glycerol carbonate preferably is 15 pts.mass or more and 60 pts.mass or less based on 100 pts.mass of the total of the glycerol carbonate and the dimethyl carbonate.SELECTED DRAWING: None
