additives and their effects on concrete

Carbon dioxide - Wikipedia

Carbon dioxide (chemical formula CO 2) is an acidic colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth''s atmosphere as a trace gas.The current concentration is about 0.04% (412 ppm) by volume, having risen from pre-industrial levels of 280 ppm.Read more

Self Healing Concrete - an overview | ScienceDirect Topics

The self-healing flakey additives developed by Jonkers and Mors (2012) were also tested in outdoor conditions, by adding them to a commercially available repair mortar. A 8 m 2 degraded concrete wall was pretreated by removing the degraded layer up to or until behind the reinforcement. The healing agent containing mortar was applied by spraying. Observations were made regarding practicality ...Read more
