COMPOSITIONS AND METHODS RELATING TO INCREASED CARBON DIOXIDE UPTAKE IN MIXING AND CURING OF CONCRETE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18184314 titled 'COMPOSITIONS AND METHODS RELATING TO INCREASED CARBON DIOXIDE UPTAKE IN MIXING AND CURING OF CONCRETE
Simplified Explanation: Cementitious compositions containing lime can increase carbon dioxide uptake and be used in various cementing methods.
- Lime-containing cementitious compositions
- Increase carbon dioxide uptake
- Used in pre-casting, cast-in-place, and wellbore cementing
- Carbon dioxide can be added during mixing, pre-conditioning, or curing
- Delivery of carbon dioxide as a gas or gas-entrained admixture
Key Features and Innovation: - Lime in cementitious compositions enhances carbon dioxide uptake - Versatile use in different cementing methods - Carbon dioxide can be added at various stages of the process - Gas or gas-entrained admixture delivery options
Potential Applications: - Construction industry - Oil and gas well cementing - Infrastructure projects
Problems Solved: - Increased carbon dioxide uptake in cementitious compositions - Enhanced performance in cementing operations - Potential environmental benefits

Commercial Applications: Title: Lime-Containing Cementitious Compositions for Enhanced Carbon Dioxide Uptake Potential commercial uses include: - Cement production - Construction companies - Oil and gas industry for wellbore cementing
Prior Art: Research on lime-based cementitious materials and carbon dioxide uptake in cementing operations.
Frequently Updated Research: Ongoing studies on the impact of lime in cementitious compositions on carbon dioxide sequestration and environmental sustainability.
Questions about Lime-Containing Cementitious Compositions: 1. How does the addition of lime enhance carbon dioxide uptake in cementitious compositions? 2. What are the potential long-term benefits of using lime in cementing operations?
Original Abstract Submitted
Cementitious compositions comprising lime, which may be foamed or non-foamed compositions, may increase carbon dioxide uptake of the cementitious compositions. Said cementitious compositions may be used in various cementing methods including pre-casting methods, cast-in-place methods, and primary or secondary cementing operations in a wellbore. The carbon dioxide may be added to the cementitious compositions during mixing, during pre-conditioning, during curing, or any combination thereof. Further, the carbon dioxide may be delivered as a gas (e.g., a gas that includes 1 vol % to 100 vol % carbon dioxide) or as a gas-entrained admixture that includes the gas, water, and a foaming agent.
